<p>A lock device includes a receiver having an outer peripheral surface that is attached to a side surface of a gear (rotating body) and rotates together with the gear (rotating body) and a solenoid pin whose tip is able to be in pressure contact with the outer peripheral surface of the receiver upon reception of the solenoid pin on the outer peripheral surface. The outer peripheral surface of the receiver includes a groove (recess) wider than the tip of the solenoid pin and projections projecting from the groove (recess). The solenoid pin has a tapered face at the tip. The height of the tapered face is at least at a level at which the tapered face is in contact with a corner of the projection with the tip being in contact with the groove (recess).</p> |
