Abstract: PURPOSE: To enhance shearing strength and bending strength without increasing mass by reinforcing the flange of a main body within a area turned downwardly while receiving the load to buckling or bending by a plate or a shell and connecting a structure member comprising plastic to the flange by a spacer member. CONSTITUTION: An elongate main body 1 comprising plastic has an opened cross-sectional area contour and the edge part reinforcing part 2 on an open side part is singly or doubly bent and a flange 3 is reinforced by a thin-walled plate or shell 4 within an area turned downwardly while receiving the load to buckling or bending. The plate or shell 4 is connected to a web 6 or connected to the flange 3 of the main body 1 by a spacer member 7. The spacer member 7 is formed by the rib laterally extending with respect to the longitudinal expansion of the main body 1 or a semi-hard foamed layer or a hard foamed layer or a honeycomb-shaped material composite.
