  • Patent number: 10059290
    Abstract: An impact absorbing portion and a bumper reinforcement are formed in one piece, so an intermediate member for connecting the impact absorbing portion to the bumper reinforcement is no longer necessary. Therefore, the generation of stress concentration is able to be inhibited. As a result, load transmission efficiency with which a load is transmitted from the bumper reinforcement to the impact absorbing portion is able to be improved.
