Since the rotation knob is provided with an excessive turning force, the protrusion and the groove regulate the rotation angle of the rotation knob to a predetermined rotation angle, and the protrusion and the groove receive the turning force. Further, as described in claim 7, since the groove on the inner peripheral surface of the case is made up of a plurality of grooves for restricting the projections of the rotary cylinder at different rotation angles, the case and the rotary cylinder are separated from each other. Multiple rotation angles of the rotary knob can be supported simply by changing the mounting angle.
