PROBLEM TO BE SOLVED: To decrease the number of parts and reduce costs. SOLUTION: In an ignition switch, a cylindrical driver 1 is rotatably provided in relation to a housing 3, and the driver 1 is so arranged as to be automatically restored by the action of a return spring 2 in an annular groove 1a of the driver in the turning movement in a turning region. One end 2a of the return spring 2 is so arranged as to be engaged with the housing 3, the other end 2b of the return spring 2 is engaged with the driver 1, at least either end is engaged with a circumferential cutout 1b formed on the driver, and therefore, the axial movement of at least either end of the return spring is regulated by the cutout, and slipping of the return spring is prevented without using any conventional stopper. |
