PROBLEM TO BE SOLVED: To avoid dispersing or reducing the power of pressing a supporting rod at the connection part of the supporting rod and a supporting plate onto the supporting plate, and to avoid unfastening the connection of the supporting rod and the supporting plate by surely holding it. SOLUTION: A passing line (14), which passes the core of revolution (9) of a stopper (8) and the contact point (12) of the stopper (8) and the supporting rod (4), is made to be at right angles to the supporting rod (4) and the engagement face (10) of the engagement hole (6a) in the direction of axis (9) of revolution.
