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.

First claim

1 . A vehicle body reinforcing structure comprising:
a vehicle body structural member that is made of metal, the vehicle body structural member having a first wall portion, and a pair of second wall portions that are bent from both end portions of the first wall portion and extend-out toward sides facing one another; a first reinforcing member that is bent-plate-shaped, the first reinforcing member being disposed at an inner side of the vehicle body structural member, the first reinforcing member being formed integrally of a fiber reinforced resin material, and the first reinforcing member being continuously superposed with and adhered to at least two inner wall surfaces that are continuous at the vehicle body structural member; and a second reinforcing member that has a pair of superposed portions, a pair of mounting portions, and a connecting portion, the pair of superposed portions being disposed at the inner side of the vehicle body structural member and superposed, via the first reinforcing member, with end wall surfaces that structure both end sides of the at least two inner wall surfaces that are continuous, the pair of mounting portions being connected in forms of steps to the superposed portions and directly joined to wall portions that structure the end wall surfaces, and the connecting portion connecting end portions, at sides opposite the mounting portion sides, of the pair of superposed portions.

2 . The vehicle body reinforcing structure of claim 1 , wherein the second reinforcing member is bent in shapes of cranks along step portions, the step portions being formed between regions where the first reinforcing member is superposed with the end wall surfaces and regions where the first reinforcing member is not superposed with the end wall surfaces.

3 . The vehicle body reinforcing structure of claim 1 , wherein
the first reinforcing member is continuously superposed with and adhered to three inner wall surfaces that are continuous at the vehicle body structural member, and the connecting portion spans in a rectilinear form between the end portions, at the sides opposite the mounting portion sides, of the pair of superposed portions, and forms a closed cross-section together with the first reinforcing member.

4 . The vehicle body reinforcing structure of claim 1 , wherein
the first reinforcing member is continuously superposed with and adhered to three inner wall surfaces that are continuous at the vehicle body structural member, and the connecting portion has a mating portion that is superposed, via the first reinforcing member, with the inner wall surface of the first wall portion.
