Abstract: A shock absorbing member is provided having a sequential destruction capability and protection against electrolytic corrosion on fastening-fixing portions thereof to be fastened to a bumper reinforcement or a vehicle body. Embodiments include a shock absorbing member between a bumper reinforcement and a vehicle body, including a distal end portion fastened to the bumper reinforcement; a base end flange portion fastened to the vehicle body; and an absorbing member body extending in a vehicle front-rear direction and connecting the distal end portion and the base end flange portion. The absorbing member body includes a carbon fiber-glass reinforced plastic layer. Fastening-fixing portions of the distal end portion and the base end flange portion are composed of glass fiber reinforced plastic layers.

Abstract: A front vehicle-body structure is provided that allows for lower deceleration for occupants by facilitating breakage of frame members in the event of an oblique collision. Embodiments include a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A first frame connects an upper portion of the suspension housing and an upper portion on a vehicle-width-direction inner side of a dash panel, a second frame connects the upper portion of the suspension housing and an upper portion of a hinge pillar, and a third frame connects a lower portion of the suspension housing and a lower portion on the vehicle-width-direction inner side of the dash panel. In the event of an oblique collision, the first frame and the second frame break inward in vehicle plan view, and the third frame breaks in a Z-shape in vehicle plan view.

Abstract: A front vehicle-body structure of a vehicle is provided that allows for lower deceleration (so-called G) for occupants in the event of an oblique collision, which involves the largest load input, while restraining a load in a shear direction from being input to connecting portions of frames. A front vehicle-body structure of a vehicle includes a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A plurality of frames connecting the suspension housing and a vehicle cabin structural member are provided, and at least one frame of the plurality of frames is configured to be facilitated to break in a Z-shape in vehicle plan view in the event of an oblique collision.
