Claims

[Scope of utility model registration request]

Cutting an outward annular groove at the end of the shaft of the volume switch, and cutting a vertical groove parallel to the axis between the outward annular groove and the tip of the shaft,
An inward annular groove and a protrusion are provided on the inner surface of the mounting tube, which is connected to the center of the inner surface of the synthetic resin knob and has an inner diameter equal to that of the shaft, at locations corresponding to the outer annular groove and vertical groove of the shaft. The mounting cylinder is divided into semi-cylindrical parts by grooves cut parallel to the axis, giving flexibility in the diametrical direction, and the protrusions and longitudinal grooves are aligned so that they face each other when the knob is fitted onto the shaft. A volume switch knob mounting device in which elastic rings are fitted into both annular grooves.
