られる。As shown in FIG. 9, when the chassis frame collides with the collision surface 12, the side member 2 'of the chassis frame is deformed, for example, in a lateral bending mode. During this deformation, the inflection portion 11, which is one of the weak points of the side member body 2 ', is largely buckled. Due to this buckling, the chassis frame is greatly deformed in the front-rear direction, and there is a problem that a living space of a cab (not shown) is reduced. For this reason, as shown in FIG. 10, various reinforcing means for further reinforcing the side member body 2 'to increase the rigidity can be considered.

It is fixed and arranged. The reinforce 1 does not have the same cross-sectional shape at all positions in the longitudinal direction, but has a shape that swells at the tip end side of the second cross member 4 as shown in FIGS. . That is, the reinforce 1 is formed of the corrugated body 10 on the distal end side, and is formed of the substantially U-shaped body 100 other than the distal end side. In addition, as for the detailed structure, the substantially U-shaped body 100 of the other portion also has a shape slightly changed depending on the place. That is, the closing plate 3 follows the shape of the closing plate 3. The reinforce 1 has a slightly bent shape in the longitudinal direction. Although the corrugated body 10 and the substantially U-shaped body 100 are integrally connected, they may be separate bodies.

い。Next, the detailed structures of the corrugated body 10 and the substantially U-shaped body 100 of the reinforcement 1 will be described with reference to FIGS. As shown in FIG. 4, the corrugated body 10 includes an upper flange plate 10a and a lower flange plate 10b, a substantially U-shaped portion 10d protruding therebetween, the substantially U-shaped portion 10d, the upper flange plate 10a and the lower surface. A flat plate portion 10c connecting the flange plate 10b,
10c and the like are formed by bending into an integral structure. The upper flange plate 10a contacts the upper inner surface of the closing plate 3, and the lower flange plate 10b contacts the lower inner surface of the closing plate 3. Further, the flat plate portions 10c, 10c are in contact with the inner side surface of the closing plate 3. As described above, the corrugated body 10 abuts and is fixed to almost the entire inner surface of the closing plate 3 except for the substantially U-shaped portion 10d. In the present embodiment, the substantially U-shaped portion 10d is formed as a single unit and formed into a U-shape, but may be a wavy curve or a plurality of waveforms.

The substantially U-shaped portion 100d has its opening side fixed to the inner surface of the closing plate 3. Accordingly, the substantially U-shaped body 100 is made of a material having lower rigidity than the corrugated body 10 described above. As shown in FIG. 3, the cross-sectional shape of the substantially U-shaped member 100 slightly changes in the longitudinal direction according to the shape of the side member member 2 '.

It is kept uniform. As described above, at the time of an external force acting at the time of a collision or the like, buckling deformation of the inflection portion 11 is suppressed to a minimum, and the amount of lateral bending of the chassis frame is suppressed to a minimum, and the chassis frame is dispersed vertically. This reduces the amount of deformation of the chassis frame in the front-rear direction. Therefore, the living space of the cab is maintained, and the safety of the vehicle can be improved.

実な溶着が行われる。FIG. 6 shows a method of fixing the reinforcement 1 having the above structure. As shown, the reinforce 1 is fixed to the inner surface of the closing plate 3 before closing the opening side of the side member 2. That is, in the case of the present invention, the closing plate 3 is formed from a material in which the reinforcement 1 is welded in advance. Since the reinforcement 1 is welded to the inner surface of the closing plate 3 in a single piece state by using the welding tool 9, the welding operation is much easier and more reliable than the operation of welding a reinforcing member or the like to the side member 2 side. Welding can be easily performed and welding distortion can be easily corrected. The closing plate 3 to which the reinforcement 1 is welded is inserted into the side member 2 as shown by the arrow in FIG. 6, and the corner of the joint is welded. As described above, the welding operation in the present invention is easily performed, and secure welding is performed.

る。According to the present invention, the inflection portion of the chassis frame is reinforced and the rigidity of each portion can be made uniform, so that local buckling deformation when an external force acts is eliminated. For this reason, the amount of lateral bending of the chassis frame is suppressed to a minimum, and the chassis frame is dispersed vertically. As a result, the amount of deformation in the front-rear direction is reduced, living space is secured, and vehicle safety is improved. Further, in the present invention, the welding operation of the reinforcing member is easily and reliably performed, so that the efficiency of the welding operation and the reliability can be improved.
