Claims

[Scope of utility model registration request]

In the bumper installed at the end of the vehicle, there is a back-up beam that is attached to the vehicle body via a pair of stays that are spaced apart from each other in an almost symmetrical manner, and a collision energy absorbing member that is attached to the outer surface of the back-up beam. Equipped with a face member,
The collision energy absorbing member includes a pair of high-density collision energy absorbing members disposed substantially symmetrically so that the mutual spacing between the pair of stays is slightly narrower than the mutual spacing between the same stays, and the remainder thereof. A collision energy absorbing bumper for a vehicle, comprising a low density collision energy absorbing member.
