CROSS MEMBER WITH DUCT FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a light-weight cross member with a duct by integrally and parallel forming a cross member body part composed of a hard resin cylindrical body and a duct part composed of a hard resin cylindrical part and foaming and filling hard foaming body in the cross member body part. SOLUTION: A cross member 10 with a duct is arranged in the back side of an instrument panel along the car width direction and constituted of a body part 11 and fitting parts 13 in its both sides. The body part 11 connects the cross member body part 12 to a duct part 20 in its side face so as to be parallel integrally formed. The cross member body part 12 is constituted of a hard resin cylindrical body matched with the length in the car width direction. Polypropylene and fiber reinforced resin are used as the hard resin. Hard foaming body is expanded and filled in the cross member body part 12 from a material filling port (h) to enhance the rigidity. The hard foaming body to be filled is preferably to be a normal temperature hardening type hard polyurethane foaming body from the viewpoint of the formability and rigidity.
