Abstract

[Problem] The present invention aims to provide a reciprocating movement device that can suppress the operating load with a simple configuration. [Solution] The reciprocating device 1 comprises a case, a reciprocating member 3, a biasing member 4, and a cam member 5. The reciprocating member 3 is provided with a first engaging portion E1. The cam member 5 is provided with a first cam surface 511, a first holding portion 521 that engages with the first engaging portion E1 so that the reciprocating member 3 is held in a forward holding position, and a second holding portion 522 that engages with the first engaging portion E1 so that the reciprocating member 3 is held in a retracted holding position. When the object to be connected moves from a first state to a second state, the reciprocating member 3 rotates from a first rotation position to a second rotation position in the circumferential direction D2 while its movement in the retraction direction D12 is restricted. At the second rotation position, the restriction on movement in the retraction direction D12 is released, and the reciprocating member 3 is guided within the case to move linearly in the retraction direction D12.

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). In the device described in Patent Document 1, the retractable member rotates circumferentially while being pushed in the retracted direction between its forward-held position and its retracted position. Therefore, in addition to the force in the retracted direction, a force in the rotational direction (circumferential direction) is required, resulting in a high operating load when pushing the retractable member. As a solution to the operating load described above, there is a technology described in Patent Document 2. The device in Patent Document 2 comprises a pusher that moves in the forward and backward directions, and a control ring and control sleeve provided to hold the pusher in the forward and backward holding positions. The pusher, which is the forward and backward member, rotates when it engages with the lid, which is closed from an open state. Then, as the pusher is pushed down by the lid, a projection on the control ring contacts the inclined surface of a projection on the control sleeve, causing the control ring to rotate relative to the control sleeve. After the control ring has rotated a predetermined amount, the pusher moves in the forward direction due to the biasing force of the spring, and the projection on the control ring and the projection on the control sleeve engage axially, holding the pusher in the backward holding position. In the above operation of the pusher, since the pusher only moves linearly in the backward direction after rotating when engaging with the lid, the downward pushing load on the pusher is small.
