For this reason, the buckling limit stress of the face plate and the rib can be further improved. For this reason, when a high compressive stress is applied to the corners, it is only necessary to increase the minimum thickness, and the weight can be reduced. Further, since the buckling preventive member 51 comes into contact with the face plate or the rib at the tip of the piece, the contact between the two can be facilitated.
