して得られた中空形材で形成した。Therefore, the inventor of the present invention has made a bumper device using a stay formed of a steel plate and a bumper device using a stay formed of a hollow shape obtained by extruding aluminum or its alloy. Were mounted on the vehicle bodies of automobiles, and a test was performed in which an impact force was applied from the front.
The bumper skin of each bumper device was made of synthetic resin, and the reinforcing member was made of a hollow material obtained by extruding aluminum or its alloy.

ことが可能であることがわかった。Further, when the hollow shape member is arranged so that its axial direction, that is, the extrusion direction, and the direction in which the hollow shape member is compressed and deformed, that is, the front-back direction of the car body, the hollow shape member is subjected to buckling load. It turns out that it can withstand enough. This structure does not need to provide a reinforcing portion inside the hollow profile, which makes it easier to manufacture the hollow profile. For these reasons, regarding collision in the bumper device, it is made of aluminum or its alloy. It has been found that it is possible to improve the impact resistance by using an extruded hollow profile.
