In the present invention, an operation knob (14) is provided with a knob outer section (22) that forms an outer shell, and a knob inner section (24) into which one edge of a lever section (12) is inserted. The knob inner section (24) has a claw section (32) that allows insertion when the lever section (12) is inserted, and once the lever section (12) has been inserted, hooks the lever section (12) towards the inner side of the knob inner section (24). A groove section (30) is formed in the lever section and extends in a direction perpendicular to the axis direction of the lever section (12). The knob outer section (22) is made up of two parts, which are an outer casing (22a) and a knob cover (22b). The knob cover (22b) is provided with protruding sections (28), which protrude towards the outer casing (22a) and fit into the groove section (30) when the lever section (12) is attached to the knob inner section (24). |
