PROBLEM TO BE SOLVED: To enhance operation feeling in operating an operation body in simple constitution. SOLUTION: A switching device 1 has an outer frame 2 and a rotor 13, and a spring 14 whose edge parts are fixed to the outer frame 2 and the rotor 13 is arranged between the bottom surface 7 of the outer frame 2 and the rotor 13. The rotor 13 is operated through an operation knob 3. Circular arc-shaped first and second main body side projections 9, 10 having an inclined part and a step difference part are installed in the bottom surface, and circular arc-shaped first and second operation body side projections 19, 20 having an inclined part and step difference part are installed so as to correspond to the main body side projections 9, 10 in the rotor 13. The rotor 13 has a rod body 18, and the rod body 18 projects from a through hole 8 according to the operation of the rotor 13 to conduct switching operation. The operation feeling of the operation knob 3 in the operation of the switching device 1 is enhanced by the twisting force of the spring 14 in addition to the friction force caused by the sliding of the inclined parts of the projections 9, 10 and the inclined parts of the projections 19, 20. |
