ている。1 to 4, the vehicle body frame is the vehicle body 2.
The main frame 3 is a pair of left and right main frames 3 extending in the front-rear direction, and a plurality of cross members 4 arranged in a ladder shape between the main frames 3. The front cross member 4 provided at the forefront is formed in a U-shape in cross section, and is connected to the lower surface of the floor with its opening side facing upward. Front cross member 4. The tip of the main frame 3 is abutted against and welded to the side surface of the main frame 3, and both ends of the main frame 3 are welded to the inner surface of the side panel 5. A plurality of reinforcing plates 6 are provided on the inner surface of the front cross member 4°, which are welded between the front and rear plates 4at and 4b and to the bottom plate 4c.

上を図っている。This reinforcing plate 6 has four sides bent to form a flange portion 6.
a is provided, and the front cross member 4.a is provided through this flange portion 6a. Front and back and bottom play of F4a
+ 4b, welded to ac. Reinforcement plate 6
Beads 7 are provided on the plate surface in the front-rear direction to improve its strength.
ビード７は第５図のように、上下方向に入れてもよく、
あるいは第６図のように上下方向に折り目８を入れても
よい。The bead 7 may be placed in the vertical direction as shown in Fig. 5.
Alternatively, creases 8 may be made in the vertical direction as shown in FIG.
