The cover member includes legs to be engaged with the notch portions of the actuating member. The first slot of the actuating member acts as a guide when it is attached to a mounting rod, and the second slot of the actuating member may support the mounting rod after the actuating member and cover member are connected, whereby the actuating member may be rotatably and removably attached to the mounting rod.

Abstract: Disclosed is a structure for fixing a knob to a part to be operated through the knob, e.g. a switch of an electric circuit and the like. The fixing relies upon snap-fitting or engagement projections (or recesses) formed on the inner wall of the cap-shaped knob with recesses (or projections) formed on the surface of the part. At least one of the knob and the part is provided with at least one elastic tab unitary therewith, which tab exerts, when the knob is fitted to the part, a resilient force to bias the inner wall of the knob away from the part, so as to eliminate the shakiness of the knob on the part, affording a stable and safe fixing without necessitating unextraordinarily high dimensional precision of the knob and the part.

Abstract: A construction for attaching a knob to a manipulation rod of a push-button type actuating mechanism. The knob has a cap-like shape with an outer wall and an inner cylinder having a bore. A snapping protrusion is formed at the lower end of the inner peripheral surface of the outer wall. The snapping protrusion has a tapered section protruding inwardly from the inner peripheral surface of the outer wall and a snapping step formed on the inner peripheral surface of the outer wall. The manipulating rod has a flange formed at its intermediate portion and resilient tongues formed on the upper end thereof. As the rod in inserted into the bore of the inner cylinder of the knob, the outer peripheral surface of the flange slides along the tapered section of the snapping protrusion spreading the outer wall outwardly and then comes into snapping engagement with the snapping step.
