Abstract:
1. An operating device for a state-changing element whose state changes by being mechanically displaced, comprising: a detent mechanism for displacing and positioning a displacement member included in the state-changing element, an actuator for driving the detent mechanism, an output angle detection means detecting a rotation angle of an output shaft of the actuator, and a control unit that controls the actuator, the detent mechanism including a detent member that displaces the displacement member by being tilted by the actuator, and a positioning member that maintains a resting position of the detent member, the actuator including an electric motor that generates rotational power, the output shaft that is coupled coaxially with a spindle of the detent member and so as to be capable of integral rotation, and a deceleration mechanism that decelerates the rotational power generated by the electric motor, and outputs the decelerated rotational power from the output shaft, the control unit including an initial motion means that, in a case of receiving a request to change the state of the state-changing element and changing the position of the detent member, reduces play in the rotation direction that exists in a coupling portion between the spindle and the output shaft from after driving of the electric motor until the output shaft rotates, and a management means that, when it has been determined that the play has been reduced at a time of detecting the start of rotation of the output shaft by the output angle detection means, sets a value obtained by tacking on play in the rotation direction that exists in a coupling portion between the spindle and the output shaft to a spindle rotation angle necessary for a position change of the detent member corresponding to the request, as a target rotation angle of the electric motor after it has been determined that the play has been reduced.
