の強度や剛性にも問題があつた。(Prior art) Conventionally, near both ends of the cowl, a closed cross section extending forward from the front pillar is formed by three components: the cowl side top, the wheel apron reinforcement, and the dash panel top. However, the connection between the closed cross-sectional structure and the front pillar is weak, and there have been problems in preventing collisions, such as preventing the windshield from falling off. There were also problems with the strength and rigidity of the front pillar and hinge pillar.

とを特徴とする。(Structure of the Invention) In order to achieve the above-mentioned object, the present invention provides a dash panel upper, a cowl side upper, and a cowl side upper part of the horizontal part of the darts panel upper extending in the vehicle width direction. The wheel apron reinforcement located on the outer side of the top forms an upper closed section connected to the front pillar and extending forward, and each of the inner panel and outer panel of the front pillar is connected to the bottom of the dash panel top. It is integrally branched into a hinge pillar portion extending downward at the dash panel top and an extension portion extending forward to near the front end of the dash panel top, and the upper end of the extension portion of the inner panel is connected to the cowl side top at the dash panel top. The upper ends of the extensions of the outer panel are joined to the joints with the wheel apron reinforcement at the dash panel top, and the extensions of the inner panel and the outer panel are connected to the dash panel top. The front portions of both extension portions are joined and closed, and extend in the front-rear direction along the upper closed cross section with the dash panel upper. It is characterized by a lower closed section structure separated from an upper closed section.

となくフロントピラーとの結合強度が向上する。(Effects of the Invention) According to the present invention having the above configuration, the upper closed section is joined to the front pillar, the lower closed section is joined to the upper closed section via the dash panel upper, and the outer panel and inner panel of the front pillar are connected to each other. Since the upper closed section extending toward the front of the vehicle body is connected directly to the front pillar through the lower closed section, the strength of the connection with the front pillar is improved without causing stress concentration. .

る。 In addition, the collision load that enters the upper closed section extending toward the front of the vehicle body can be distributed directly to the front pillar and via the lower closed section to the hinge pillar section, that is, it can be distributed above and below the dash panel top. Load can be absorbed efficiently.

とがなく、ピラーが変形するおそれが少ない。 Furthermore, since the upper and lower closed cross sections are partitioned by the darts panel top and the darts panel upper is made to act as a knot, the strength of the connection between the upper and lower closed cross sections and the dash panel top is high.
Since it is joined to the upper closed section pillar and the lower closed section is formed by the pillar, the cowl portion including the dash panel upper and the pillar are densely and firmly joined. That is, the torsional and bending loads that act on the pillar when the door is opened and closed can be distributed to the upper and lower closed sections and to the cowl portion via the upper and lower closed sections. As a result, stress is not concentrated on the pillar, and there is little risk of the pillar deforming.
また、カウルサイド部分には、サスペンシヨン
からの突き上げ荷重が作用するが、上下閉断面及

ができる。 In addition, although the thrusting load from the suspension acts on the cowl side portion, it can be dispersed to the pillar via the upper and lower closed cross sections and this closed cross section, and deformation of the cowl side portion can be effectively prevented. .
