Abstract
In a click structure of a rotary electric part according to the present invention, a click member and a biasing member are formed as separate members, so the resilience of the biasing member is not affected by the heat generated during molding; besides, the spring span of the biasing member can be made long, thus ensuring a satisfactory resilience over a long period. The rotary electric part. Long-term durability, good click feeling and reduced noise are also characteristic features of the rotary electric part of the invention.
Claims8
A rotary electric part comprising:
- a rotary member having a plurality of concaves and convexes;
- a click member for engagement with and disengagement from the concaves and convexes;
- a biasing member for urging the click member elastically in a direction in which the click member comes into pressure contact with the concaves and convexes;
- and
- a holding member for holding the biasing member,
- the click member coming into engagement with and disengagement from the concaves and convexes with rotation of the rotary member and creating a click feeling,
- wherein the click member and the biasing member are formed as separate members, the click member has a body for engagement with and disengagement from the concaves and convexes and also has a convex portion which is integral with the body in a direction perpendicular to a moving direction of the body, the body of the click member is guided by side walls of a concave portion formed in the holding member, and the convex portion is guided by a concave groove.
