In the above case, one end of the reinforcing plate reinforces the bent portion of the frame member, and the other end of the reinforcing plate reinforces the bottom of the inclined member around the support bracket. Since a plurality of places where the occurrence of the stiffness tends to occur are reinforced by a single reinforcing plate, the stiffening is achieved with a simple structure and without increasing the weight.
