ECCENTRIC PREVENTING STRUCTURE OF KNOB FOR ELECTRIC APPLIANCE

摘要

An eccentric preventing structure of a knob for an electronic device is provided to improve operation reliability by preventing eccentricity of the knob when operating the knob. An eccentric preventing structure of a knob for an electronic device comprises inclined projections(24a) and inclined grooves(12a). The inclined projections are positioned along the outer surface of the knob at certain intervals. The inclined grooves are formed at the inner surface of a knob hole(12) of a front panel(10) to correspond to the inclined projections. The inclined projections are inclined in the projecting direction of the knob(24), and the inclined grooves are inclined toward the rear of the front panel.
