部は、プレス成型された縦部材９で連結されている。As shown in FIG. 2, the front bulkhead 3 includes a press-molded upper member 6, a pair of die-cast molded side members 7, and an extruded lower member 8. By substituting the left and right ends of the lower member 8 and the lower ends of both side members 7 by welding, and connecting the upper ends of both side members 7 and the upper member 6 with bolts (not shown), a subassembly is formed. Have been. Further, an intermediate portion in the left-right direction between the upper member 6 and the lower member 8 is connected by a press-formed vertical member 9.

設けられている。The front bulkhead 3 has a vertically intermediate portion of both side members 7 connected to the side frame 2 using bolts. Thereby, the front bulkhead 3 can be repeatedly attached to and detached from the side frame 2 as desired. In this case, a recess 7a corresponding to the hexagonal contour of both side frames 2 and a hole H1 for loosely inserting a bolt are provided at an intermediate portion in the vertical direction of both side members 7, and a female screw hole T1 is formed in both side frames 2. (See FIG. 3).

And a curved portion 2b coupled to the front dashboard 1
Are formed as separate members. These are formed by inserting the rear end of the straight portion 2a and the front end of the curved portion 2b into a plug-in manner by means of a stake-in fitting, and then moving the rear end of the straight portion 2a from the bolt insertion hole H2 provided at the rear end of the straight portion 2a to the front end of the curved portion 2b. Screw hole T2
Are connected by screwing a bolt (not shown) to the connector, so that only the straight portion 2a can be repeatedly attached and detached.
【００１３】なお、上記構成によれば、フロントバルク
ヘッド３のアッパ部材６のみを単独で取り外せるので、
エンジン着脱時の作業性を高める上にも有利である。According to the above configuration, only the upper member 6 of the front bulkhead 3 can be detached alone.
This is also advantageous in improving workability when attaching and detaching the engine.

交換することができるようになる。By the way, as described in the section of the prior art, it is substantially impossible to restore the aluminum material when it is plastically deformed. Even when only the tip of the side frame 2 is deformed due to the collision, the repair work becomes extremely large. According to the present invention, a plurality of members constituting a vehicle body frame are connected to each other using a connecting means that can be repeatedly attached and detached, such as bolts / nuts. It can be easily replaced.

ストを低減する上に大きな効果が得られる。As described above, according to the present invention, it is possible to ensure high shock absorption characteristics by using an aluminum material,
The ease of repair at the time of deformation can also be improved. Moreover, unlike the welding, there is no need to consider the residual stress due to thermal strain, and even if the tolerances in the manufacturing stage of each member are increased, the required accuracy is secured during assembly by loosening the bolt insertion holes. Therefore, a great effect can be obtained in reducing the total cost in manufacturing the frame.
