Abstract

The present disclosure relates to an operation device that improves assemblability. In the knob unit (30), the number of teeth of the first gear (52) in the operation shaft (50) is the same as the number of projections (54A) of the rotating body (54). In addition, in the rotating shaft (70), the number of teeth of the second gear (73) is the same as the sum of the slit part (76A) and the light shielding part (76B) in the rotating plate (76). That is, the number of teeth of the second gear (73) is the same as the number of detection by the photointerrupter (102) per rotation of the rotary plate (76). Thus, the operation shaft (50) and the rotation shaft (70) can be mounted on the support member (40) without using a jig or the like for determining the mounting positions of the operation shaft (50) and the rotation shaft (70). Therefore, the assembling property of the operation device (10) can be improved.

Description

Operating device Technical Field The present invention relates to an operating device. Background The switch device (operation device) described in patent document 1 includes a rotation knob, a shaft portion integrally rotatably coupled to the rotation knob, a first gear integrally rotatably coupled to the shaft portion, a transmission gear engaged with the first gear, a second gear engaged with the transmission gear, and a magnet integrally rotatably coupled to the second gear. Thus, when the rotary knob is rotated, the magnet rotates in association with the rotation of the rotary knob. The magnetic sensor is disposed so as to face the outer peripheral portion of the magnet. In the magnet, four S-poles and N-poles are alternately arranged in the circumferential direction of the magnet. Thus, when the operator rotates the rotary knob, the magnetic sensor detects switching between the S pole and the N pole of the magnet facing the magnetic sensor, and thereby detects the rotational position of the magnet and the rotational position of the rotary knob. Further, a regulating plate constituting a regulating mechanism is integrally rotatably provided on the shaft portion, and a plurality of regulating grooves are formed in an outer peripheral portion of the regulating plate. The ball forced by the spring is embedded into the throttling groove, and the ball is clamped with the throttling plate. Thus, the rotation knob is held at a predetermined rotation position by the throttle mechanism, and a throttle feeling is given when the rotation knob is rotated. In summary, in the above-described switch device, the rotation knob can be held at a predetermined rotation position by the throttle mechanism, and the predetermined rotation position of the rotation knob can be detected by the magnetic sensor. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2020-87718 However, in the above-described switching device, there is room for improvement in the points shown below. That is, for example, when the second gear is engaged with the transmission gear so as to be offset from the normal mounting position by one tooth amount, the relative rotational position of the magnet with respect to the magnetic sensor is changed. In this case, the rotational position of the actually rotated rotary knob is shifted from the rotational position of the rotary knob detected by the magnetic sensor, compared with the case where the second gear is mounted at the normal position, and therefore the rotational position of the rotary knob cannot be accurately detected. Therefore, in assembling the first gear, the transmission gear, and the second gear, it is necessary to assemble the gears by determining the positions of the gears using a jig or the like. Therefore, in the above-described switching device, there is a possibility that the assemblability may be deteriorated.
