摘要

PURPOSE: To provide a bent rectangular tube excellent in strength by forming the recessed part at compression side bent face to be excellent in strength and to provide a bent rectangular tube excellent in appearance by bending the corner part of compression side bent face toward recessed part side. ;CONSTITUTION: In a bent rectangular tube P, a recessed part 20 is formed so that at a compression side bent face Pa, a curvature in the longitudinal direction is larger at a center part 21 than both at corner parts 22. Also, a recessed part 24 is formed so that a curvature in the longitudinal direction is smaller at a center part 25 than at both corner parts 26. In this case, the sides 23, 27 formed at recessed parts 20, 24 oppose against the bending force applied to the bending direction of the bent rectangular tube with working together with both horizontal side faces Pc, Further, both corner parts 22 of the compression side bent face Pa is bent toward the recessed part 20, it is excellent in appearance.;COPYRIGHT: (C)1995,JPO
