仁疋，若對支柱套殼接合一閉斷面構造之上部框架 時，因支柱套殼部份之剛性會變得非常高，使得其在車輛 衝擊吸收特性方面變得不利。又，在以往之車體構造，也 有構造過於複雜之問題，若使用閉斷面構造之上部框架 寺因八疋在形成上部框架内側面板之内表面上接合支柱 套成將外側面板後端接合到前柱，所以支柱套殼及前柱 各自接。在各別之板面，因而有車體構造組立精度下降之 虞0 因此本發㈣為解決±述課題❿提供— 構造就能保持良好之衝擊能量吸收特性，同時，伴=In the case of joining the upper frame of the closed-section structure to the pillar casing, the rigidity of the pillar casing portion becomes very high, which makes it disadvantageous in terms of shock absorption characteristics of the vehicle. Moreover, in the conventional vehicle body structure, there is also a problem that the structure is too complicated. If the upper frame is used, the upper frame is joined to the inner surface of the inner panel of the upper frame by the gossip. The front pillar, so the pillar sleeve and the front pillar are connected to each other. In the case of each board, there is a decrease in the accuracy of the body structure. Therefore, in this (4), in order to solve the problem, the structure can maintain good impact energy absorption characteristics.

In a preferred mode of the invention to solve the above problems, the pillar casing is connected to the instrument panel, and the front end wall portion of the vehicle compartment is connected to the instrument panel in the vehicle width direction inner side. When the above-described best mode is used, the support case and the reinforcing member are connected to the front end (four) of the vehicle compartment through the instrument panel and the reinforcing member, so that (4) more effectively complements the other preferred form of the present invention for solving the above problems. The reinforcing member is provided with a rib extending in the front-rear direction of the vehicle body. When the best mode is used, the rigidity of the reinforcing material is increased, and the movement of the pillar shell and the front panel to the rear of the front panel is further reduced or the other preferred embodiment of the present invention for solving the above problems is The ribs (18) are disposed opposite the upper ends (4c) of the strut casings (4). When the best mode is used, the pillar sleeve can be more efficiently reinforced. 0 7042-7503-PF 6 1286108. In another preferred embodiment of the invention to solve the above problems, the upper edge of the reinforcing material and The lower edge portion has a flange portion that protrudes outward in the vehicle width direction. When this optimum form is used, the rigidity of the reinforcing material is increased, and the movement or deformation of the pillar casing and the instrument panel toward the rear of the vehicle body can be further reduced. In another preferred mode of the invention to solve the above problems, an attachment portion that is joined to the instrument component is provided at the tip end of the reinforcing member. When using this best form, the assembly accuracy of the instrumented parts can be increased. In another preferred aspect of the present invention, the front end side wall portion of the vehicle compartment to which the reinforcing member is joined is an extension portion extending from the inner panel in front of the vehicle body of the front pillar, and the reinforcing member After that, the end system is opposite to the front pillar. When this optimum mode is used, it can efficiently absorb the impact energy to the front pillar. In another preferred mode of the invention to solve the above problems, the reinforcing member is wider than a joint portion with the pillar end portion (11). When this optimum form is used, the strut casing can be efficiently reinforced with a lighter weight construction. [Embodiment] Hereinafter, embodiments of the invention will be described in detail based on the drawings. The figure is a perspective view of a vehicle body structure according to an embodiment of the present invention; and the second figure is a 7042-7503-PF 7 1286108 of the present invention because "the upper end of the rigid pillar shell 4 and the pillar shell 4 and the instrument panel 5 are joined. The portion 19 extends inwardly from the reinforcing member 14 so that the pillar casing 4 can be retracted, and the intrusion of the instrument panel 5 into the vehicle compartment 13 can be prevented, and the reinforcing member can be made in the same manner as the front body structure. The column forms a closed-section structure & or, instead of forming the reinforcing material itself into a closed-section structure, the reinforcing member 14 is formed into a plate shape, and at the same time, the flange portion 16, 17 and the rib 18 are provided to form a bellows. In this way, a simple shape can be formed, and at the same time, the rigidity of the reinforcing member 14 can be efficiently increased to absorb impact energy. That is, by providing the reinforcing member 14 from the vicinity of the upper end of the strut casing 4 to the inner front pillar 8, the frontal collision energy can be absorbed with only minimal reinforcement. Thereby, the intrusion of the instrument panel 5 into the passenger compartment 13 is prevented, and the passenger's foot P can be protected. Next, the method of assembling the vehicle body will be described using the fifth to seventh figures. As shown in Fig. 5, the assembly of the vehicle body 1 firstly sets up a frame assembly 2 consisting of the side sill 2, the struts 4 and the reinforcing members 14, and the like, and the instrument panel 5 and the front pillar 6 and the like. The column assembly 21 is composed, and then the frame assembly 20 and the column assembly 21 are assembled. The frame assembly 20 and the column assembly 21 are assembled by arranging the column assembly between the reinforcing members 14 at a predetermined position, but the reinforcing member 14 joined to the frame assembly 20 becomes The guides when the cylinder assembly 21 is inserted allow the assembly to be easily performed. Thereby, since the difference generated by the frame assembly 20 and the column assembly 21 can be reduced, the assembly accuracy of the vehicle body 1 can be improved. 7042-7503-PF 10 1286108 Further, as shown in FIGS. 6 and 7, when the assembly of the vehicle body 1 is completed, in the front of the vehicle body 1, even when the protective panel 22 is joined to the mounting portion 15, the joint is engaged. In the side of the vehicle body 1 in which the accuracy is improved, the accuracy of the assembly around the protective panel 22 is also improved. If the problem such as the αα quality of the parts such as the protective panel 22 occurs, it can be easily modified, and since the composition reproducibility or the recovery property is excellent, there is no need to worry about whether the operator has experience. In other words, by forming the reinforcing member 14 into a plate shape, it is possible to have the flat inner surface 14a and the outer surface 14b to join the members to the members, so that the vehicle body 1 can be made simple in structure, and not only can Efficiently absorbs impact energy' while also improving the accuracy of the car body. Therefore, when the vehicle body structure of the present invention is used, the reinforcing member 14 is provided in a plate shape extending in the front-rear direction of the vehicle body, and at the same time, the rear end thereof is joined to both ends of the front portion of the vehicle compartment 13; It is disposed on the inner side of the reinforcing material "in the vehicle width direction; and the instrument panel 5 is disposed behind the front and rear direction of the pillar body of the pillar shell 4; and is disposed on the outer side of the pillar sleeve 4 and the instrument panel 5 in the vehicle width direction, because the crucible is provided with high rigidity The upper end 4c of the strut casing 4 and the joint portion 19 of the strut casing 4 and the instrument panel 5 straddle the reinforcing member 14 inwardly of the front pillar 8, so that the vehicle body 1 can be made simple in structure and the reinforcing material can be efficiently lifted. 14 rigidity ' At the same time, maintaining good impact energy absorption characteristics, can also strengthen the car body strength. Moreover, because the assembly of the car body 1 can be easily carried out, it can also improve the accuracy of the car body assembly. The rib 18 and the flange portion 16 extending in the front-rear direction of the vehicle body are formed on the w-base, and the upper end 4c and the joint 7042-7503- are supported by the Guardian PF 11
