The connection between the portion b1 and the lower end portion b2 with the laterally concave rib a becomes narrow, stress is concentrated there, and the buckling strength cannot be further increased. When the amount is reduced, the thickness of the trunk becomes thinner and the buckling strength decreases, so that the problem of restriction on the reduction has arisen.
