That is, the head 27 is pushed against the spring force of the coil spring 34 so that the inner peripheral surface of the head 27 corresponds to the outer peripheral surface of the large-diameter tubular portion 22 of the second tubular member 14. In this state, when the head 27 is rotated while being further pushed in, the female screw portion 35a of the head 27 is screwed into the male screw portion 35b of the large diameter tubular portion 22 of the second tubular member 14. As a result, the head 27 of the operating member 15 is locked to the large-diameter tubular portion 22 of the second tubular member 14.

When the clock module 7 is switched by such a switch device 10, first, the lock mechanism 35 unlocks the head 27.
