[0002]

2. Description of the Related Art As a conventional vehicle body structure of this type, for example, one shown in FIG. 5 or FIG. 6 is known.

In such a vehicle, the front part 2 of the cabin of the vehicle 1 is
A steering wheel 3 is attached to the tip of the vehicle, and a steering shaft body 4 that transmits the rotation of the steering wheel 3 to the front wheels to perform steering is provided.

The front part 2 of the passenger compartment mainly includes a dash lower panel 5 and a pair of dash side panels 6, 6 formed integrally with both sides of the dash lower panel and extending substantially in the front-rear direction of the vehicle. It is composed of

The dash side panel 6 is mainly constructed by connecting a dash side inner panel 6a and a dash side outer panel 6b at respective rear ends 6c and 6d.

The steering shaft body 4
Is rotatably inserted into the column main body, and is fixedly supported by a steering member 7 extending along the vehicle width direction via an upper bracket.

The steering member 7 is formed such that a pair of mounting flange portions 8 having a flat plate shape are welded and integrated with both ends 7b, 7b of an elongated steering member body 7a. Have been.

The mounting flanges 8, 8
Are fixed to the inner side surfaces of the dash side inner panels 6a, 6a by welding or using bolts 9,..., Nuts 10,..., Washers 11, etc. so that the steering member body 7a is fixed to the vehicle body. It is configured.

The dash side inner panel 6
Reinforcing reinforcement members 12 are lined on the rear surfaces of the a and 6a in correspondence with the mounting flange portions 8 and 8, and are fastened together by the bolts 9 and nuts 10 and the like. ing.

The rear end portions 6c and 6d of the dash side inner panel 6a and the dash side outer panel 6b form a portion below the front edge of the door opening, and the door opening has As shown in FIG. 5, the door 13 is provided so as to be openable and closable.

A door guard bar 14 is provided between the inner panel 13a and the outer panel 13b of the door 13 to reduce the impact due to a side collision. The door guard bar main body 14a of the door guard bar 14 has an elongated shape, extends along the vehicle front-rear direction, and has a front end 1.
A mounting flange portion 14c formed integrally with the door 4b is connected to the front end surface 13c of the door 13.

Next, the operation of the conventional vehicle body structure will be described.

In the conventional vehicle body structure constructed as described above, when the dash lower panel 5 enters the vehicle compartment front part 2 due to a primary collision input due to a front collision, as shown by a white arrow in FIG. The steering member 7 enters the vehicle interior together with the dash lower panel 5.

A dash side inner panel 6a for supporting both ends of the steering member 7 is shown in FIG.
