Abstract: An impact absorbing member structure of a vehicle includes: a pair of left and right rear side frames; a pair of left and right crash cans containing a plurality of first carbon fibers arranged so as to continuously extend in a forward/rearward direction; and a bumper reinforcement attached to tip end portions of the pair of rear side frames through the pair of crash cans. Each of the crash cans is formed as an open-section member including: a side wall portion extending in the forward/rearward direction; and a tip end wall portion continuous with the side wall portion and including an attaching portion to which the bumper reinforcement is attached.

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 bonnet inner panel includes a central protrusion portion protruding upward in a vehicle elevational view and a rear protrusion portion located in back of the central protrusion portion, which are arranged side by side in a vehicle longitudinal direction, a deep-drawn groove is provided between the both protrusion portions to extend in a vehicle width direction, and a hinge reinforcement is provided to extend from a position beside the rear protrusion portion to a position at a rear end of the central protrusion portion, passing through beside the deep-drawn groove. Thereby, the hinge support rigidity of the rear portion of the bonnet having the central protrusion portion can be increased, so that occurrence of any improper deflection or vibration caused to the bonnet by the traveling vibration, the traveling-air pressure or the like can be prevented.

Abstract: An impact absorbing structure includes an impact absorbing member made of CFRP, and the impact absorbing member includes a pair of left and right side wall portions and upper and lower coupling wall portions each coupling the side wall portions. Each of the pair of side wall portions includes a plurality of curved portions. Each of the curved portions is formed such that a leftward/rightward direction depth thereof decreases toward a front side. Each of the pair of side wall portions includes: a plurality of first carbon fibers arranged to extend in a forward/rearward direction and constituting most of reinforced fibers contained in the side wall portion; and a plurality of second carbon fibers arranged to extend in a direction intersecting with the first carbon fibers. The plurality of second carbon fibers are arranged at both thickness direction end vicinity parts of each of the side wall portions.

Abstract: An impact absorbing structure for a vehicle according to the present invention includes: a resin frame member extending in a vehicle front-rear direction and having an opening portion in a surface thereof on one side in a vehicle width direction; and a strut member disposed in the opening portion of the frame member. The frame member includes a frame body having the opening portion, and a rib protruding at least either upward or downward from the frame body and extending in the vehicle front-rear direction. The strut member is disposed between a pair of opening edges for defining an upper edge and a lower edge of the opening portion and at a position abuttable against the paired opening edges, when the frame member is deformed by input of a load at a time of oblique collision from upward or oblique collision from downward.
