  • Patent number: 10988179
    Abstract: A suspension member is mounted on the side members of an underbody. On the rear portion of the suspension member, spacers are provided between the suspension member and the underbody. Each spacer includes a bracket. The front end surface of the bracket is opposed to the rear wall surface of a main suspension body. During a frontal collision, the rear wall surface of the suspension member abuts against the bracket, whereby retreat of the suspension member is reduced.

  • Patent number: 9764774
    Abstract: A vehicle body front portion structure includes a front pillar, a dash portion and a load transmission portion. The dash portion includes a dash panel. The load transmission portion includes a dash side structure portion that is fixed to a surface facing he vehicle rear side of a vehicle width direction outer side region of the dash portion, a pillar side structure portion that is fixed to a surface facing the vehicle width direction outer side of the pillar inner panel, and an intermediate structure portion that is connected to at least one of the dash side structure portion or the pillar side structure portion. The intermediate structure portion penetrates a hole portion and is set at a location at which a load that acts on the dash side structure portion when there is a frontal collision is transmitted to the pillar side structure portion.
