Claims

[Scope of utility model registration request]

A rotary electric component comprising a click plate having a protrusion and a cam in which recesses and protrusions are continuously formed at a predetermined pitch on the outer periphery, and the protrusion is brought into elastic contact with the cam of the click plate. In the click mechanism, the contact angle formed by the contact between the protrusion and the recess of the cam is changed in the thickness direction of the click plate, and at least one of the protrusion and the click plate is movable. Click mechanism for rotating electrical parts.
