  • Vehicle front portion structure
    Patent number: 9902350
    Abstract: An upper and lower pair of first beads that extend in a longitudinal direction are formed at an inner side wall of a front side spacer. The first beads project to the vehicle width direction outer side. Therefore, when a collision load diagonally to the rear-left side is inputted to a front end portion of the inner side wall, the first beads act to support the inner side wall adjacent above and below the first beads from the vehicle width direction outer side. Accordingly, tilting deformation of the inner side wall toward the vehicle width direction outer side at the beginning of a micro-wrap collision of a vehicle is suppressed. An overall dimension in the vertical direction of the general portions of the inner side wall is specified to be greater than an overall dimension in the vertical direction of the first beads.
