Provided to restrict the cross section . Here, constraining the cross-section of the pillar-in hose means preventing the pillar-in hose from being deformed and firmly supporting and reinforcing.

As the bracket, for example, a steel plate processed into a rectangular shape having a substantially L-shaped cross section is used. The bracket is fixed to the inside of the pillar rein hose by spot welding, for example, above or below the check rein hose (see FIG. 2). The relationship between the check-in hose and the bracket may be reversed up and down , as long as one end having a substantially T-shaped cross section can be formed at the end (the positions of 1 and 2 in FIG. 2 are reversed). ).

[0010] The door check, for example, have a door check arm and the locking device. Then, the locking member has one end portion facing the surface of the check reinforcements and the bracket, i.e. it is preferred that the mounting fixed to the door mounting side. Thereby, when the door mounting pillar is excessively opened, the torsional rigidity is further improved (see FIG. 3).

[0011]

In the pillar for door mounting according to the present invention, a check-rein hose having a substantially U-shaped cross section is disposed in the pillar-rein hose as described above. Therefore, the check rein hose restrains the pillar rein hose in a state where both end faces (both side plates) are in contact with the pillar rein hose.

On the other hand, a bracket having a substantially L-shaped cross section is fixed to the door mounting side of the pillar rein hose for mounting the door check, and also to the check rein hose. For this reason, the bracket has a substantially T-shaped cross section at one end of the check-rein hose in a state of being back-to-back with the check-rein hose (see FIG. 2). Therefore, the rigidity of the pillar rein hose and the pillar outer is improved, and the mechanical strength and durability such as torsional rigidity when the door is excessively opened are improved.

In particular, when the door check portion is attached via a locking member having a substantially T-shaped cross section, mechanical strength such as torsional rigidity and durability are further improved. Also, in the present invention, the check-rein hose has a role of a bulkhead, that is, a reinforcing material. As described above, according to the present invention, it is possible to provide a door mounting pillar having a sufficient torsional rigidity even when the door is excessively opened.
