Abstract

[Problem] The present invention aims to provide a reciprocating device that can be made compact in the axial direction. [Solution] The reciprocating device 1 comprises a case, a reciprocating member 3, and a switch operating member 9. The reciprocating member 3 is configured to be held in a forward holding position and a backward holding position. The reciprocating member 3 has an operating part 314 that protrudes in a direction intersecting the axis X of the reciprocating member 3 and moves the switch operating member 9 between an operating position and a non-operating position. The switch operating member 9 is provided on the side of the reciprocating member 3, and the rotation of the operating part 314 in at least the circumferential direction D2, accompanying the rotation of the reciprocating member 3 in the circumferential direction D2, causes the switch operating member 9 to move between an operating position and a non-operating position, thereby turning the switch SW on or off.

The switch operating member is provided on the side of the reciprocating member, The rotation of the reciprocating member in the circumferential direction, along with the rotation of the operating part in at least the circumferential direction, causes the switch operating member to move between the operating position and the non-operating position, thereby turning the switch on or off.

  3. The forward/backward movement device according to claim 2, wherein the shaft portion is arranged substantially parallel to the axis of the forward/backward member.
  4. The aforementioned reciprocating device further includes a cam member that engages with the reciprocating member at the end of the reciprocating member on the retraction side, The reciprocating device according to claim 3, wherein the operating portion of the reciprocating member is configured to contact the operated portion of the switch operating member with the outlet of the reciprocating member and the forward-facing end of the cam member in the axial direction.
  5. The reciprocating movement device according to claim 2, wherein the operated portion has an operated surface that is inclined to rotate around a predetermined axis as the reciprocating member moves in the axial direction while in contact with the operating portion.
  6. When the connected object changes from the first state to the second state, the retractable member moves from the forward holding position in the retraction direction, moves in the forward direction via the return position, and is then held in the retraction holding position. When the connected object changes from the second state to the first state, the retractable member moves from the retracted holding position in the retracted direction, moves via the folding position in the forward direction, and is then held in the forward holding position. (1) When the connected object changes from the first state to the second state, While the reciprocating member moves a predetermined amount from the forward holding position to the backward direction, the operated portion is pressed against the other by the operating portion against the biasing force of the shaft biasing member and rotates around the predetermined axis, and the switch operating member moves from the operating position to the non-operating position. From the moment the forward-retracting member moves a predetermined amount in the retraction direction from the forward-holding position until it is held in the retraction-holding position via the return position, the operated portion is pressed against the other by the operating portion around the predetermined axis against the biasing force of the shaft biasing member, and the switch operating member is held in the non-operating position. (2) When the connection target changes from the second state to the first state, Until the reciprocating member moves from the retracted holding position in the retracted direction and moves a predetermined amount in the forward direction via the folding position, the operated portion is pressed by the operating portion against the biasing force of the shaft biasing member, and the switch operating member is held in the non-operating position. After the reciprocating member has moved a predetermined amount in the forward direction via the folding position, the rotation of the reciprocating member in the circumferential direction releases the pressure applied by the operating part to the operated part around the predetermined axis, and the biasing force of the shaft biasing member causes the shaft to rotate in one direction around the predetermined axis, moving the switch operating member from the non-operating position to the operating position. The reciprocating device according to claim 2.
  7. The forward and backward movement device further comprises a cam portion provided within the case, configured to rotate the forward and backward member in the circumferential direction as the forward and backward member moves in the axial direction, The reciprocating member is provided with an engaging projection that protrudes in a direction intersecting the axis of the reciprocating member so as to rotate the reciprocating member in the circumferential direction as the reciprocating member moves in the axial direction, and interacts with the cam portion. The reciprocating member is held in a forward-holding position, where it has moved in the forward direction, and in a backward-holding position, where it has moved in the backward direction, with the engaging projection guided by the cam portion. The forward and backward movement device according to claim 1, wherein the operating part is provided on the engaging projection.

Description

This invention relates to a device for moving forward and backward. Devices in which a member moves forward and backward relative to a case, such as a device for opening and closing a lid covering a vehicle's fuel filler cap, are configured to reciprocate between a position where the member protrudes from the case and a position where it is retracted to be housed within the case (see, for example, Patent Document 1). The apparatus described in Patent Document 1 comprises a housing, a pusher that moves forward and backward relative to the housing, and a control ring and control sleeve provided to hold the pusher in a forward and backward holding position. In the apparatus of Patent Document 1, the pusher, which is the forward and backward moving member, moves forward and backward together with the control sleeve, and is held in the forward and backward holding positions by axial engagement between a projection provided on the control ring and a projection provided on the control sleeve. In Patent Document 1, the control sleeve is provided so as not to rotate relative to the housing, and moves in conjunction with the pusher in the forward and backward directions (axial direction of the pusher). Furthermore, the device described in Patent Document 1 includes a switch for detecting whether the lid is open, depending on the axial position of the pusher. This switch is operated by a switch actuation part that protrudes downward (in the retraction direction) from the lower end of the control sleeve. While the pusher is configured to move axially and rotate circumferentially, the control sleeve and switch actuation part move only axially, without rotating circumferentially, to perform the on/off operation of the switch.
