Patent ID: 8084703

Claim:
An electronic component comprising: a rotation shaft including a rod-shaped intermediate section, a rotatable cylindrical operation section covering an upper part of the intermediate section and capable of being mounted with an operation knob, and a coupling section coupling an upper end of the intermediate section with the operation section; a signal generating section configured to generate an electric signal in response to rotation of the operation section; and a bushing having a cylindrical section supporting the intermediate section; wherein the coupling section has strength at which the coupling section breaks when a load of a predetermined level or higher is applied to the operation section from an axial direction of the rotation shaft; wherein the upper end of the intermediate section projects from the bushing; wherein an inner diameter of a part of the operation section that is coupled to the intermediate section via the coupling section is larger than an outer diameter of the cylindrical section; and wherein vertical thickness of the coupling section is smallest at a position outside an outer periphery of the cylindrical section.
