<p>There is provided an operation knob supporting structure having a main body portion mounted to an instrument panel having a slanted surface, in which when a predetermined force is applied to an operation knob a fragile portion thereof fractures, allowing the operation knob to retract into the main body portion until a projection thereof from the main body portion is less than a predetermined value. AV equipment 1 includes a case 2 and a support structure 12 having the operation knob 15, a support portion 21 supporting the operation knob 15 and the fragile portion 22 which fractures when a force pushing the operation knob 15 towards a front face 2a of the case 2 exceeds the predetermined force. The operation knob 15 includes a tilt regulating portion 26 having an end face 26a arranged to closely contact with a surface 36a of a printed wiring board 36 of the support portion 21 when the fragile portion 22 fractures, preventing the operation knob 15 from tilting.</p> |
