Abstract
To reduce generation of noise at the time of clicking by integrally providing an engaging member made of synthetic resin with a spring plate, integrally providing both ends of the spring plate with a support member made of synthetic resin, and press contacting the support member to a retaining member against the press contact of the engaging member to an uneven surface part. A semi-cylindrical part 6a of an engaging member 6 slides on the outer circumference of a rotary plate 5 while rotating together with the plate 5 according to rotary operation. Since the member 6 is elastically energized to press contact with the outer circumferential part of the plate 5 by a spring plate 7, operation force required for rotating a rotary shaft 2 varies when the part 6a engages with each uneveness part 5a sequentially so that a clicking feeling is sensed by an operator through the shaft 2. Then the member 6 moves following the part 5a, the plate 7 repeats bending and support members 8 provided on both ends of the plate 7 slide and vibrate on a support part 3b of a retaining member 3. However, generation of noise is extremely small since the support member 8 is made of resin.
