A small diameter portion is formed at the free end of the mounting tube by connecting the tubes, and an annular groove is cut near the tip of the shaft into which the small diameter portion can be elastically engaged. The side surface is a conical surface whose diameter gradually increases toward the tip, and when the knob is fitted onto the shaft, the inner surface of the knob is in close contact with the tip surface of the shaft, and the tip of the small diameter portion is in contact with the conical surface. The relative position of the small diameter part and the annular groove is determined so that
Volume switch knob mounting device.

Claims

[Scope of utility model registration request]

A knob mounting structure for a volume switch, characterized in that a plurality of circumferential protrusions are provided on the inside of an inner cylinder of a resin knob, and the same number of grooves corresponding to the protrusions are provided on the outer periphery of the shaft.
