STOPPER STRUCTURE OF ROTARY ELECTRONIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a stopper structure of a rotary electronic component capable of preventing deformation of a stopper-use protrusion fitted to a rotating body and smoothly maintaining rotation of the rotating body at all times. SOLUTION: The stopper structure is provided with a rotating body 50, a case 10 having a container part 11 containing the rotating body 50, and rotating body rest member 90 set on the container part 11 for axially supporting the rotating body 50. A stopper-use protrusion part 55 is provided at an outer periphery side face of the rotating body 50. A stopper-use locking part 103 for stopping the rotating body 50 at a given rotating position by making the stopper-use protrusion part 55 of the rotating body 50 is provided at the rotating body rest member 90. A protrusion part deformation preventing part 107 protruded toward a rotating direction of the rotating body 50 is provided outside in a radius direction of a contact face 109 of the stopper-use locking part 103 on which the stopper-use protrusion part 55 abuts.
