[PROBLEMS] To provide a resin bumper for a vehicle, which has excellent energy absorption at the time of collision and is easily recycled, and a method for efficiently manufacturing the resin bumper for a vehicle. A vehicular resin bumper comprising a resin skin material (2) made of a hollow molded product and a resin foam (3) foamed in a hollow portion (2 ') of the skin material (2) and filling the hollow portion (2'), At least a part of the skin material 2 and the resin foam 3 is made of a polymer having the same repeating unit. Further, the vehicle resin bumper of the present invention, when blow molding the resin skin material, fills the hollow portion of the hollow molded product formed in the blow molding die with the raw material for the resin foam, and then in the hollow portion. It is efficiently manufactured by supplying a heating medium to the above to foam the resin foam raw material, and then taking out the hollow molded article from the blow molding die. |
