Abstract
Abutment projections ( ) of a resin-made driver member (not shown) are inserted in the opposite end portions of a key groove ( ) of a metal-made turnable member ( ) in the circumferential direction. A key portion (B ) of a receiving cylindrical portion is inserted between the abutment projections ( ). The interval between the abutment projections ( ) in the circumferential direction is set to be slightly larger than the width of the key portion (B ). By doing so, when a transmission section is turned into an open position or a closed position, the abutment projections ( ) and the key portion (B ) are collided with each other, thereby generating a click sound. Moreover, since both the abutment projections ( ) and the key portion (B ) are formed of resin, they can be prevented from getting worn out soon.
