Abstract: A rotating operation type electronic component has a rotation shaft and a signal generating section. The rotation shaft has a rod-shaped intermediate section, a cylindrical operation section, and a coupling section coupling the upper end of the intermediate section with the operation section. The rotatable operation section covers the upper part of the intermediate section, and has an operation knob mounted thereon. The signal generating section generates an electric signal in response to the rotation of the operation section. The coupling section has strength at which it breaks when a load of a predetermined level or higher is applied to the operation section from an axial direction of the rotation shaft.
