  At this time, as shown in FIG. 3, the position restricting portion 22 of the operation shaft portion 20 comes into contact with the inner end portion of the cylindrical member 13, and the pulling position of the operation shaft portion 20 is restricted. In this state, of the first and second waterproof rings 24 and 25, the first waterproof ring 24 is in elastic contact with the inner surface of the small-diameter hole portion 13 a of the tubular member 13, and the second waterproof ring 25. Is disposed in the large-diameter hole 13 b of the cylindrical member 13.
