る。[Prior Art] In an open body as shown in FIG. 6, when a lateral shake occurs due to a torsional primary vibration, about 10 cm in the vehicle front-rear direction at three locations indicated by double arrows A, B, C in the figure. It has been found that the strain energy density in the range is high, and the reinforcing material E is added in the body locker D as shown in FIG.
A bulk head is provided at a location to reinforce the bulk head.

As shown in JP-A-56-53966, cut and raised pieces are provided on the upper wall F and the lower wall G of the channel-shaped reinforcing member E shown in FIG. 7, and the cut and raised pieces are joined together. Means have also been proposed.

減少してしまう欠点がある。[Problems to be Solved by the Invention] In the means disclosed in Japanese Patent Laid-Open No. 56-53966, the cut-and-raised pieces are formed on the reinforcing member E at a plurality of positions close to each other in the vehicle front-rear direction, and each plate is a plate. If a bulkhead is formed, the cut-and-raised area will increase, and the effect of improving the rigidity of the entire body locker will decrease despite the addition of the reinforcing material E.

It cannot be denied that the strength is insufficient for a bulkhead that reinforces each range having a high strain energy density of about 10 cm.

The first cut-and-raised piece of the quadrangle having a folding curve is cut and raised inward at a position close to the open edge of the channel at the same phase position of the portion and the lower wall portion, and from the side wall portion of the reinforcing member, A rectangular second cut-and-raised piece having a bending curve at positions substantially corresponding to both side edges of the first cut-and-raised piece in the longitudinal direction of the reinforcing member is cut and raised toward the channel-shaped opening edge. The first and second cut-and-raised pieces are integrally joined at the overlapping portion.

Despite the opening area of the body locker, the bending and torsional rigidity of the body locker can be improved, and since a separate bulkhead is unnecessary, the number of parts is reduced and the weight is reduced accordingly.

保できる効果がある。[Effects] The present invention has the above-described configuration and operation, and cut-and-raised pieces formed on the upper wall portion, the lower wall portion, and the side wall portion of the channel-shaped reinforcing member are integrated at the overlapping portion. Since the reinforcing structure portion having a closed cross section and a substantially closed cross section is formed in both the horizontal cross section and the vertical cross section by coupling, the body blocker can be formed only by the channel type reinforcement without providing a separate bulkhead. This has the effect of ensuring the required bending rigidity and torsional rigidity.
更に、別体のバルクヘッドを使用する必要が無いので、
部品点数を削減でき、その分重量を軽減できる効果を有
している。Furthermore, since it is not necessary to use a separate bulkhead,
The number of parts can be reduced and the weight can be reduced accordingly.

強度低下を僅かなものに留めうるものである。In addition, due to the formation of the cut-and-raised pieces, the openings formed in the upper wall portion and the lower wall portion are inconsistent with the positions formed in the side wall portions, so that the openings of the channel-shaped reinforcing material are formed. The decrease in strength can be kept to a slight extent.
