A switch device (10) which is capable of preventing eccentricity of a push knob (15) mounted to a central hole (14) of a rotary knob (13). A ring-shaped rib (22) provided on an inner peripheral surface of the central hole (14) of the rotary knob (13) supports a front portion of the push knob (15), and a rib (24) provided on an outer peripheral surface of a rear portion of a push knob body (23) integral with the push knob (15) is supported by a knob holder (25), so that the push knob (15) and the push knob body (23) integral therewith can be supported at two front and rear locations. Accordingly, it is possible to prevent eccentricity of the push knob (15) in the central hole (14).
