Further, the reinforcing structure 1 includes a vertical reinforcing rod 3, a front supporting reinforcing rod 4, a left and right bridging rod 5, and a rear supporting reinforcing rod 6.

The vertical reinforcing rod 3 and the front supporting reinforcing rod 4
The left and right bridging rod 5 and the rear support reinforcing rod 6 can be disassembled and assembled by using appropriate locking means 7 such as bolts and nuts, mounting brackets, and the like, for locking the members between the members. It is preferable to form it as follows. If the mounting angle at that time is made freely adjustable, fine adjustment at the time of assembly becomes possible.

An automobile 2 for setting a reinforcing structure 1
Bolts 9a, 9b, 9c for attaching the seat belt 8 are set in advance in the body of the first embodiment.

Further, if there is a small mounting hole 11 used for mounting a retrofitting member at a position on the inner surface of the body just below the lower edge 10a of the front door 10 of the front door 10 of the vehicle 2, this is left as it is. However, if the mounting holes 11 do not exist, the mounting holes 1 may be used.
Only 1 needs to be formed separately.

An upper flange 12 is provided on an upper portion of the vertical reinforcing rod 3 of the present invention, and a lower flange 1 is provided on a lower portion.
3 are provided. These two flanges 12 and 13 have
Small holes 12a and 13a are formed.

Next, a front flange 14 is provided at the front end of the front support reinforcing rod 4, and a rear flange 15 is provided at the rear end of the rear support reinforcing rod 6. These flanges 1
Small holes 14a and 15a are also formed in the holes 4 and 15 as described above.
