A first turning member is formed in a bottomed cylindrical shape. A pivot is convexly formed on the bottom of the first turning member, and a packing is wound around the first turning member. A boss is convexly formed on one surface of a second turning member, and a packing is wound around the boss. A pivot opening is formed in the other surface of the second turning member. The boss is inserted into the first turning member. The pivot is inserted into a ring-shaped waterproof member and a plain washer. The waterproof member surrounds the pivot opening. The waterproof member is sandwiched between the bottom of the first turning member and the end surface of the boss.
