  In general, as shown in FIG. 1, the steering member 1 is configured to extend in the vehicle width direction and support the steering shaft 3, so that the side of the driver's seat such as a dash panel or a front pillar constituting the vehicle body 2 is provided. It is attached to the panel 2a and the passenger side side panel 2b, and is attached to the vehicle body 2 with respect to one end side (normal driver seat side) 1a of the steering member 1 on the other end side (normal passenger seat side) 1b. An attachment mechanism is used that allows the longitudinal dimension to be adjusted.

  In order to constitute this mounting mechanism, one end side 1a of the steering member 1 is fixed to the driver's seat side panel 2a via a bracket 4 with bolts 5 and the other end side 1b is provided by welding or the like. The mounting flange 6 is attached to the vehicle body side bracket 7 fixed to the passenger side side panel 2b using a nut 11. At the time of this attachment, the steering member 1 is attached to the vehicle body side bracket 7 via the attachment flange 6. The mounting position of the other end side 1b needs to be configured to be adjustable in the vehicle width direction.

  As a result, the steering member mounting structure is formed due to manufacturing errors and the like, with one end side 1a of the steering member 1 being a reference end in the vehicle width direction and the vehicle width direction dimension of the other end side 2a being adjustable. The steering member 1 can be appropriately disposed at a predetermined position of the vehicle body 2 by absorbing an error between the length of the vehicle 1 and the width of the passenger compartment.

  Therefore, the conventional steering member mounting structure uses, for example, a mounting mechanism 10 that can adjust the longitudinal dimension of the other end side 1b with reference to the one end side 1a of the steering member 1, as shown in FIGS. When mounting to the vehicle body 2, the mounting mechanism 10 includes a mounting flange 6 provided on the other end side 1 b of the steering member 1, and a vehicle body side bracket 7 mounted on the passenger side side panel 2 b in a state of facing the mounting flange 6. And a projection bolt 8 fixed to the vehicle body side bracket 7 in the mounting flange 6, and a nut 11 inserted through the mounting flange 6 and screwed into the projection bolt 8. 6a has a long hole shape in the vehicle width direction, and a mounting flange is inserted through a nut 11 in the bolt insertion hole 6a. By fixing together a di 6 to the position of the projection bolt 8 is adjustably configure the lengthwise dimension of the steering member 1.

  As another prior art, as shown in FIG. 9, a mounting flange 6 is provided on the other end 1 b of the steering member 1, and first special nuts (adjustment nuts) are provided at a plurality of positions so that the mounting flange 6 is inserted. 12 is provided, and a second special nut (adjustment nut) 13 is further screwed into the first special nut 12.

In such a configuration, the bolt 8 inserted from the passenger side side panel 2b side of the vehicle body 2 is screwed into the second special nut 13, and the second special nut 13 is moved to the passenger side side panel 2b side. The second special nut 13 is brought into contact with the passenger side side panel 2b. After the contact, the first special nut 12 is further screwed with respect to the second special nut 13, and the steering member 1 is moved. Can be adjusted (refer to Patent Document 1 as a similar technique).

  Among the conventional steering member mounting structures configured as described above, in the structure shown in FIGS. 7 and 8, an error caused by a manufacturing error between the length of the steering member and the cabin width of the vehicle body 2 is caused. In order to absorb, the mounting flange 6 of the steering member 1 is not directly mounted on the vehicle body 2, but the vehicle body side bracket 7 is used, so that the number of parts is large, and the problem of increased production and assembly costs remains. Further, since the bolt insertion hole 6a of the mounting flange 6 has a long hole shape in the vehicle width direction, the contact area of the head of the nut 11 with the mounting flange 6 is reduced, and the nut 11 can be tightened by long-term use. You must also take into account the possibility that the force will loosen.

  The conventional steering member mounting structure shown in FIG. 9 is improved in that the mounting flange 6 of the steering member 1 is directly mounted on the vehicle body 2, but because of the use of two special nuts 12 and 13, etc. In addition, the number of parts is large, and after the first special nut 12 is fixed to the steering member 1 by welding or the like, it is necessary to temporarily tighten the second special nut 13 to the first special nut 12 by hand. Thus, the work of attaching the steering member 1 to the vehicle body 2 could not be fully automated.

  Accordingly, in view of the above, the present invention provides a steering member that can secure a predetermined mounting force and achieve automation of the mounting operation of the steering member even if the number of mounting parts of the steering member is reduced as much as possible to reduce the cost. The purpose is to provide a mounting structure.

  To achieve the above object, the steering member mounting structure of the present invention is a steering member mounting structure for supporting a steering shaft so as to extend in the vehicle width direction, with one end side of the steering member as a reference. When attaching to the vehicle body using an attachment mechanism in which the longitudinal dimension on the other end side can be adjusted, the attachment mechanism is fixed to the other end side of the steering member, and the vehicle interior facing the attachment flange. A project nut fixed to the surface side, a bolt inserted through the vehicle body and the mounting flange and screwed into the project nut, and a dimension adjustment deformation portion provided on the mounting flange so as to surround the vicinity of the project nut. And by screwing the bolt onto the project nut Serial size adjustment deformable portion is deformed in the vehicle body side with respect to the general portion of the mounting flange, it is characterized in that it has adjustable constituting the vehicle width direction length of the steering member.

  In the present invention configured as described above, the conventional vehicle body side bracket 7 and the like are abolished and the mounting flange is directly mounted on the vehicle body, so that the cost can be reduced due to the reduction in the number of parts, and the bolt mounting on the vehicle body side can be expected. Since it is not necessary to make the hole into a long hole shape, the tightening force of the bolt can be maximized, and since the conventional special nut etc. are not used, the temporary tightening work between the special nuts can be eliminated, and the steering It can be expected to fully automate the member installation work.

  In the first and second embodiments, the dimension adjustment deforming portion 20 is constituted by the long hole 20a provided in the mounting flange portion 6, but instead of the long hole 20a, the vicinity of the projection bolt 8 in the mounting flange portion 6 is delegated. The bead-shaped portion may be formed as described above to configure the dimension adjustment deformation portion 20.

  As described above, the present invention eliminates the conventional vehicle body side bracket 7 and the like and attaches the mounting flange directly to the vehicle body. Therefore, it can be expected to reduce the cost by reducing the number of parts, and the bolt mounting on the vehicle body side can be expected. Since it is not necessary to make the hole into a long hole shape, the tightening force of the bolt can be maximized, and since the conventional special nut etc. are not used, the temporary tightening work between the special nuts can be eliminated, and the steering Since it can be expected that the member mounting operation is fully automated, it is suitable for a steering member mounting structure for supporting a steering shaft for a vehicle such as an automobile.
