BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure of an automobile, and particularly to a vehicle body structure around a dash panel constituting the front portion of a vehicle interior.

0002

2. Description of the Related Art The structure of the front part of an automobile cabin is disclosed in, for example, Japanese Utility Model Application No. 63-133473.
The dash panel that makes up the front part of the vehicle interior, the side members such as the front pillar, cowl side panels, and side sills provided at both ends of the dash panel in the vehicle width direction, and the side members such as the cowl side panels and side sills that are connected to the side members at both ends, The steering wheel is equipped with a steering support member that extends from the front. Furthermore, as shown in the above publication, a stay that supports the steering support member at its intermediate portion may be provided so as to connect the bulge formed on the dash panel and the floor panel to the steering support member. Common.

[0003]Although not shown in the above publication, the dash panel is usually provided with a pedal bracket that supports pedals such as an accelerator pedal and a brake pedal. Conventionally, the steering support member and the pedal bracket have been provided independently.

[Problem to be solved by the invention] A dash panel is a panel that separates the vehicle interior from the space at the front of the vehicle interior (for example, the engine compartment), and prevents deformation of the front of the vehicle body, such as in the event of a collision, from reaching the interior of the vehicle. Therefore, it is desirable that the dash panel has high rigidity. Therefore, for example,
As shown in the above publication, a vehicle body is also known in which a cross member is connected to the lower part of the dash panel so as to form a closed cross section together with the dash panel to increase the rigidity of the dash panel.

[0005] In addition to an integral structure in which the body and main frame are integrally formed, the vehicle body also has a chassis frame separate from the body, to which the body is attached via a rubber mount. There is a car body. In a vehicle body in which a body and a chassis frame are separately provided, the main frame is not provided on the floor panel on the body side, so the rigidity of the vehicle body around the dash panel is also usually low. In particular, for such a car body, it is desirable to increase the car body rigidity around the dash panel in addition to providing a cross member as described above, but providing a new reinforcing member causes problems such as increasing the car weight. was there.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide an automobile body structure that can effectively utilize a pedal bracket to improve the rigidity of the vehicle body around the dash panel without increasing the vehicle weight. That is.

[0007]

[Means for Solving the Problems] In order to solve the above problems, an automobile body structure according to the present invention has a vehicle interior in which a bulge portion that bulges inward of the vehicle interior is formed at the lower part of the intermediate portion in the vehicle width direction. a dash panel that constitutes a front part; side members that constitute both side parts of the vehicle body provided at both end edges in the vehicle width direction of the dash panel; a steering support member that supports a steering shaft, the part being supported by the side member, and a part extending in the vehicle width direction between the bulge part and the side member at the lower part of the dash panel, and closing together with the dash panel. a cross member coupled to the dash panel to form a cross section; a pedal bracket for supporting pedals coupled to the dash panel between the bulge and the side member of the dash panel; An automobile body structure comprising: an upper end of the pedal bracket is connected to the steering support member, and a lower end of the pedal bracket is connected to the cross member.

Further, in order to solve the above-mentioned problems, the vehicle body structure of the present invention includes, in addition to the above-described structure, an outer edge portion of the cross member in the vehicle width direction being sandwiched between the dash panel and the side member. can.

[0009]

[Operations and Effects] As described above, in the automobile body structure according to the present invention, the upper end of the pedal bracket is connected to the steering support member, and the lower end is connected to the cross member.

The pedal bracket functions as a stay for the steering support member, and since the steering support member and the cross member are connected via the pedal bracket, the rigidity of the vehicle body around the dash panel is improved. Further, since no new reinforcing member for reinforcing the dash panel is particularly provided, there is no problem of increased vehicle weight.

As described above, the automobile body structure according to the present invention can effectively utilize the pedal bracket to improve the rigidity of the vehicle body around the dash panel without increasing the weight of the vehicle. This provides effects such as allowing the bracket to function as a stay for the steering support member.

[0012] Furthermore, the automobile body structure according to the present invention has the following features:
The outer end of the cross member in the vehicle width direction can also be held between the dash panel and the side member. In this case, it is possible to prevent the outer end of the cross member in the vehicle width direction from protruding into the interior of the vehicle due to an impact such as a collision, and it is also possible to further improve the rigidity of the area around the dash panel. .
