The portion is joined to the inner surface (the side surface on the vehicle interior side) of the extension member 16 which is also separated downward from the joint portion 23.
More specifically, the joining base portions 24 that are in close contact with the inner surface of the extension member 16 are provided at a plurality of locations along the width direction, for example, at a panel portion that forms an intermediate portion of the reinforcement member 22.
Are formed. The tip of each joining base 24 is overlapped on the inner surface of the lower extension member 16 from the joining portion 23 and joined to the inner surface by welding. The lower end of the reinforcement member 22 is inclined toward the inside of the vehicle and extends to a joint portion between the quarter inner panel member 2 and the side outer panel member 10. The flange portion 22a at the lower end of the reinforcement member 22 has a flange portion 16a formed at the lower end portion of the extension member 16 and a flange portion formed at the lower end portion of the panel portion 2b as shown in FIG. 2c and are joined together by welding.

On the side adjacent to the joint 7a), the reinforcement member 2
2, a beam-shaped portion having a closed cross section formed by a joining portion 22b in the middle of the second member and a joining portion 22c at the lower end of the reinforcement member 22, that is, a cross section extending along the wall surface of the wall portion T has a substantially triangular closed section. A beam H is formed.
【００２３】つまり、梁状部Ｈの剛性強度が、フロアパ

有効である。Therefore, the rigidity around the lower part of the gate pillar portion 20 is effectively reinforced by utilizing the reinforcement member 22. In particular, the reinforcement is effective for reinforcing the rigidity in the direction S in which the vehicle body 1 falls in the vehicle width direction as shown in FIG.

Rather than securing the rigidity from the plate thickness of 2, the rigidity is secured at the beam-like structural portion obtained by the joining method of the reinforcement member 22, so that a panel member having a large plate thickness is used for the vehicle body 1. In addition, it is not necessary to process a panel member having a large plate thickness, and material costs and processing costs are small. In addition, the reinforcement can be dealt with only by the joining method of joining the intermediate portion of the reinforcement member 22 to the inner surface of the extension member 16 and joining the lower end portion to the inner / outer panel members 2, 10. It is inexpensive.

が行える。In particular, when a separate extension member 16 is used, the structure in which the lower portion of the reinforcement member 22 is joined to the inner surface of the extension member 16 is such that the trace of the junction covers the outer surface of the extension member 16. Since it is hidden by the bumper cover 17 to be attached, the appearance may be improved. In addition, with this bonding, the gap between the joining portion U (shown only in FIGS. 1 and 4) formed by the outer panel portion and the edge portion of the bumper cover 17 attached to the extension member 16 is not damaged. That is, usually, as the reinforcement member 22 to be assembled to the vehicle body 1, a panel member having a thickness greater than the thickness of the panel members forming the skeleton such as the inner panel member 2 and the outer panel member 10 is used. Therefore, the portion closest to the joining portion U, that is, the joining portion 2 that joins both the side outer panel member 10 and the extension member 16
When the intermediate portion of the reinforcement member 22 is joined at 3, the thermal effect (distortion) greatly appears at the joining portion U, and the gap of the joining portion U changes greatly, and the appearance may be impaired. Extension member 16 away from 23
When it is joined to the inner surface, the occurrence of distortion can be suppressed to a small level, so that good reinforcement can be performed without impairing the appearance at the joint portion U.

車体が倒れる方向の剛性強度を有効に補強できる。As described above, according to the first aspect of the present invention, the existing reinforcement member can be used to lower the floor panel member depending on the manner of joining the lower portion of the reinforcement member. Since the beam-shaped part is formed on the side, the rigidity around the lower part where the floor panel member is attached, especially the rigidity in the direction in which the car body falls down is effective without increasing the thickness of the members that make up each part of the car body Can be reinforced.

スト的にも安価ですむ。In addition, since reinforcement can be dealt with only by the way of joining the reinforcement members, it is structurally simple and inexpensive.

This has the effect that the fitting portion between the outfitting member and the outer panel portion that fits with the edge can be reinforced without being damaged.
