Description

  The present invention relates to a steering support member structure.

  In a vehicle such as an automobile, a strength member such as a steering support member that extends substantially in the vehicle width direction and connects the left and right of the vehicle body is disposed at the front of the passenger compartment. A conventional steering support member is composed of an iron pipe.

  However, an iron pipe steering support member has an essential problem that its weight is heavy. Therefore, it is considered to reduce the weight by changing the material. Among them, the most prominent one is that the steering support member is made of a light alloy. Currently, research and development for that purpose is being promoted in various fields (for example, see Patent Document 1).

On the other hand, various components such as a steering column, an air-conditioning unit, an airbag module, and an audio are attached to a steering support member that is disposed in the vehicle width direction in the front part of the vehicle compartment. When the steering support member is made of an iron pipe, a mounting bracket that is a separate member is welded to the iron pipe, and these in-vehicle parts are indirectly attached via the welded mounting bracket. .
