Abstract: A vehicle front pillar structure includes a pair of front pillars disposed on both sides of a vehicle to oppose each other. An instrument panel reinforcement to which a steering portion is attached extends between the pair of front pillars (A-pillars). Each of the A-pillar includes an outer reinforcement disposed on a transversely outer side of the vehicle, an A-pillar inner portion disposed on a transversely inner side of the vehicle, and a reinforcing bracket attached to the outer reinforcement and the A-pillar inner portion. The reinforcing bracket is disposed at a position opposing an end portion of the instrument panel reinforcement.

Abstract: A body frame structure that constitutes a side and a top of a vehicle includes: a pillar inner that extends in a vehicle vertical direction on the side of the vehicle; and a rail inner that extends along a boundary line between the side and the top of the vehicle. In an overlapping portion with the pillar inner, the rail inner is formed with a rail bead that is projected to a vehicle outer side. In an overlapping portion with the rail bead, the pillar inner is formed with a pillar bead in such a shape that offsets the rail bead to the vehicle outer side so that the pillar bead is located in a recess of the rail bead.

Abstract: There is provided a composite structure, comprising a base member(s) made of metallic material, and a reinforcement member(s) made of fiber reinforced plastic including reinforcement fibers which are aligned in a uni-direction, wherein at least one slit is formed on the reinforcement member(s) so as to extend in an orientation direction of the reinforcement fibers.

Abstract: A first reinforcing reinforcement that is formed of a fiber reinforced resin material is continuously superposed with and adhered to an inner wall surface of a front wall portion, an inner wall surface of an outer wall portion, and an inner wall surface of a rear wall portion of an outer reinforcement. A pair of superposed portions of a second reinforcing reinforcement are superposed, via the first reinforcing reinforcement, with the inner wall surface of the front wall portion and the inner wall surface of the rear wall portion of the outer reinforcement. The second reinforcing reinforcement is directly joined to the front wall portion and the rear wall portion of the outer reinforcement, and the pair of superposed portions are connected by a connecting portion.

Abstract: A vehicle door structure includes a door outer panel that configures an outer plate of a side door; a door inner panel that is provided towards a vehicle width direction inside than the door outer panel, and that configures an inner plate of the side door; an impact beam disposed between the door outer panel and the door inner panel so as to run along the side door in the vehicle front-rear direction; and a bracket that is provided with an excess length portion between a first joint portion that is joined to a vehicle front-rear direction front portion of the door inner panel and a second joint portion that is joined to a vehicle front-rear direction front portion of the impact beam, with an apex portion of the excess length portion provided towards the vehicle width direction inside than the vehicle width direction position of the second joint portion.

Abstract: A vehicle body forward portion structure is provided that can ensure necessary strength and reduce the weight of a front pillar portion. In vehicle body forward portion structure, front pillar lower is formed in an overall open cross section shape that opens inward in a vehicle width direction as seen in plan sectional view as a result of front pillar outer portion being joined to pillar reinforcement lower formed from high-tensile steel plate.
