<p>The knob fitting structure has a fitting member (2) with a base including a flat portion, a stopper (4) protruding forward from the base, and a through hole provided in a flat portion. A knob (6) has projections (7) positioned on the same circle. In fitting the knob to the fitting member, when the knob is rotated while being pressed backward in a state in which the projections are kept in contact with the flat portion, the projections slice on and in friction with a flat face. When the projections hit against the stopper and the rotation of the knob is stopped, the projections and the through hole become opposite each other.</p> |
