Bumper device for vehicle

摘要

An impact absorbing device (13, 41, 46) for a vehicle includes an impact-absorbing portion (21, 47) including an inner wall surface (21a) extending smoothly in an axial direction and configured to compressively deform in the axial direction for absorbing an impact energy, a first attaching portion (22) closing an opening end of the impact-absorbing portion closer to a bumper reinforcement (16) and configured to be attached to the bumper reinforcement, a second attaching portion (23) extending from an opening end of the impact-absorbing portion closer to a side member (11) and configured to be attached to the side member, a readily deformable portion (31) provided at the impact-absorbing portion and formed by forming a plate thickness to be thinner in a partial range of the impact-absorbing portion in the axial direction, and an initial peak load restraining portion (34, 41) provided at the first attaching portion and set to be away from the bumper reinforcement in the axial direction, which are integrally formed.
