は極めて困難となる。2. Description of the Related Art Conventionally, an example of an automobile bumper reinforcement formed of an extruded aluminum material has been known for the purpose of reducing the weight. In order to ensure rigidity, the bumper reinforcement force for automobiles has a cross-sectional shape such as a day shape or a cross shape having a plurality of closed cross-section portions extending in the vehicle width direction. T is around 2 mm. However, if the extrudability of an automobile bumper reinforcement with a closed cross section is extruded using A6063S 200N class aluminum material, the extrudability is 100% higher than that of A6063S 200N class aluminum material. When an automobile bumper reinforcement with a closed cross section is extruded using an A7003S 300N class aluminum material, the aluminum material of the aluminum material is restricted by the shape of the extrusion jig for forming the closed cross section. Extrudability drops to 60%. Therefore, a higher strength aluminum material such as Y
It is extremely difficult to extrude an automobile bumper force with a closed cross section using an aluminum material of S400N grade or higher.

Assembling is not good because it needs to be fixed with an adhesive. Further, due to the fixing by the adhesive, when the flatness of the inner surface of the closed cross section is not good, the hollow member 78 made of steel plate is likely to be peeled off from the inner peripheral surface of the closed cross section 72.

る。In the automotive bumper reinforcement of the present invention,
When a compressive force is applied to the opposing surfaces of the closed cross-section structure of the bumper reinforcement body, the opposing surfaces move toward each other. At this time, the reinforcing plate member provided in the closed cross-section structure along the vehicle width direction and having both ends in contact with the facing surfaces of the closed cross-section structure bends to control the compressive deformation of the bumper reinforcement body. Therefore, the bumper reinforcement for an automobile can be made to have a predetermined strength depending on the arrangement position of the reinforcing plate material, the strength, and the like. Further, since both ends of the reinforcing plate member are fitted to the holding portions provided on the inner peripheral portion of the closed cross-section structure, the both ends are prevented from being displaced in the direction orthogonal to the vehicle width direction. Due to the compressive deformation of the force body, both end portions of the reinforcing plate material are not easily separated from the inner peripheral portion of the closed cross-section structure, and the compressive deformation of the bumper lining force body can be reliably controlled by the reinforcing plate material.
