DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge mounting structure, and more particularly to the mounting structure that allows a door hinge mounted on a fixed frame to be easily moved and adjusted.

Generally, an automobile door is attached via a hinge to a pillar having a closed cross section that constitutes a vehicle body frame. For example, as shown in FIGS. 1 to 3, a brace 2 is welded to the back side of the outer pillar 1, and a tapping plate 3 is arranged on this brace 2, while
A hinge 4 attached to a door (not shown) is arranged on the front side of the outer pillar 1, and the hinge 4 is fastened to the tapping plate 3 with bolts 5, and the outer pillar 1 is clamped between them. Furthermore, openings 1a and 2a are formed in the outer pillar 1 and brace 2, and the bolt 5 is inserted through the openings 1a and 2a. After the door is installed, its position can be adjusted. When adjusting this door, the bolt 5 is slightly loosened so that the door can be moved together with the tapping plate 3 and the hinge 4.

However, in this conventional hinge mounting structure, when tightening the bolts 5 to the tapping plate 3, it is necessary to support the tapping plate 3 on the brace 2 in advance because the pillar 1 has a closed cross section as described above. be. Therefore, considering the amount of movement of the tapping plate 3, the brace 2 is provided with stoppers 6 at a plurality of locations with slight intervals from the periphery of the tapping plate 3. A hook-shaped stopper 6a is formed which is bent in the direction, and the tapping plate 3 is disposed within the stopper 6, 6a to prevent it from coming off from the brace 2.
However, as mentioned above, since there is a slight gap between the periphery of the tapping plate 3 and the stoppers 6, 6a, the tapping plate 3 does not fit properly before the bolt 5 is installed, especially as shown in the vertical cross-sectional view of FIG. It falls down to the lower stopper 6 and the hinge mounting hole 4
The center lines O and O' between a and the screw hole 3a of the tapping plate 3 are shifted from each other. In this state, when attaching the bolt 5 to the screw hole 3a of the tapping plate 3 from the hinge mounting hole 4a,
The bolt 5 is diagonally inserted into the screw hole 3a at its tip.
You have to screw it on while searching for it. This not only makes the assembly work difficult, but also makes it impossible to assemble the hinges mentioned above, although it is customary for automobiles in particular to be assembled by continuous machine work. There was a problem with this.
