Abstract

PROBLEM TO BE SOLVED: To join an intermediate connecting member holding a cross member with a side frame inexpensively, with good productivity and without using an assembling jig. SOLUTION: An intermediate connecting member 3 is made up of an aluminum, extruded member whose cross sectional form is of a letter-U, and on both side wall parts 6, 6 of the member 3, claw parts for fitting 5, 5 projecting inward are formed through integrated, extrusion molding. A side frame 1 possesses fitting holes 4, 4, on its both side wall parts. By forcibly fitting the claw parts 55 into the fitting holes 4, 4, of the side frame 1, the intermediate connecting member 3 can be tack-welded to the side frame 1, and then they can be welded into an integrated body through welding (w).

As described above, in the frame structure of the present invention, the intermediate connecting member is formed of a member having a U-shaped cross section so that the side frame can be sandwiched from both sides thereof, and the inner connecting member has an inward direction on both side wall portions. On the other hand, the side frame has a fitting hole or a fitting recess into which the fitting claw of the intermediate connecting member is fitted, and the intermediate connecting member. Since both of the fitting claws are forcibly fitted into the fitting holes or the fitting recesses of the side frame, the intermediate connecting member is held in the side frame in the positioning temporary fixing state. Can be properly assembled to the side frame by itself without using a jig. Therefore, the assembling jig can be eliminated, the manufacturing cost can be reduced, and the productivity can be improved.

Moreover, since the intermediate connecting member is a member having a U-shaped cross section and has a structure in which both side walls are joined and integrated with the side frame, the intermediate connecting member can be made lighter while
It can have sufficient rigidity.

In this case, the intermediate connecting member is made of an extruded aluminum material having a predetermined length and having a U-shaped cross section, in which both fitting claws are integrally extruded, thereby having the fitting claws. It is possible to mass-produce the intermediate connecting member having a structure extremely easily and cost-effectively, and further reduce the cost and improve the productivity. In particular, since it is made of aluminum, it can greatly contribute to weight reduction.

Further, the intermediate connecting member is plastically deformed inwardly on both side wall portions of the extruded mold material extruded in a state where both side wall portions are inclined outward, and both fitting claw portions of the side frame are formed. By using a structure in which each fitting hole or fitting recess is forcibly fitted, it becomes possible to extremely easily assemble the intermediate connecting member to the side frame, and further improve workability. Therefore, the productivity can be further improved.
