の車輌用バンパー。[Scope of Claim for Utility Model Registration] (1) Reinforce is applied to the inner surface of the elongated substantially rod-shaped core material made of a foamed synthetic resin body located on the vehicle side, and facia is applied to at least one of the surfaces other than the inner surface. An air flow gap is provided in the length direction between the core material and the reinforcement and/or the facia, and air is supplied to the air flow gap located between the core material and the reinforcing and/or fascia. A vehicle bumper that is characterized by: (2) The inner surface of the core material, which is a long rod-like material made of foamed synthetic resin and has grooves in the longitudinal direction of the surface, is provided with reinforcement on the inner surface located on the vehicle side. The surface to be removed is coated with fascia, with at least the concave groove portion serving as an air flow gap, and air is supplied toward the air flow gap located between the core material and reinforcement and/or fascia. A vehicle bumper characterized by: (3) A vehicle bumper according to claim 1 or 2, wherein the core material is made of foamed polypropylene.
