A pivot pin P and a positioning boss portion 11 for the pivot pin P are formed at a position close to the door panel D of the door opening operation case 1.

Reference numeral 100 shown in FIG. 2 is a protrusion provided on the door opening operation case 1 to prevent the operating finger from slipping.

In detail, the fixture 10 shown in FIG. 4 is formed by fixing a threaded rod 102 to a hole in a boss portion 101 of the door opening operation case 1, and protrudes from the inside of the door of the door panel D. A nut 103 is screwed into the threaded rod 102.

Also, as can be seen from Figure 4, door panel D
The first bracket 2 provided inside the door of
Through the door panel D, the door opening operation case 1 and the door opening operation case 1 are fastened together to the door panel D by the above-mentioned fixture 10. Therefore, the first
The first bracket 2 is provided with a hole 200 through which the threaded rod of the fixture 10 is inserted, and the first bracket 2 also has a rectangular hole 20 and a Following 20, a notch 21 is provided.

By fitting into this notch 21 the convex portion 111 formed on the positioning boss portion 11 of the pivot pin P of the door opening operation case 1 shown in FIG. 1, the position of the pivot pin P with respect to the mounting surface 22 of the bracket 2 is determined,
Therefore, the position of the pivot pin P is determined by fitting the positioning boss portion 11 of the door opening operation case 1 into the notch 21 of the first bracket 2.

The unlocking handle 3 is shown in Figs. 2 and 4.
As can be seen from the figure, a lock release operation portion 32 (see FIG. 2) is formed at one end 31 of the door panel D that is rotatably supported by the pivot pin P and protrudes from the pivot pin P toward the outside of the vehicle. The other end 33 of the lock release handle 3 via the pin P is attached to the door panel D.
It is located on the inside of the door and is bent into a U-shape, and each piece of the U-shape is provided with a hole 331, as can be seen in FIG.

On the other hand, as shown in FIG.
is rotatably supported by a shaft pin 51 on a second bracket 5 which is installed inside the door panel D separately from the first bracket 2, and is locked via the shaft pin 51. One end (not shown) of the release lever 4 is connected to a lock release device (not shown) for a door lock provided inside the door panel D, and the other end of the release lever 4 is connected to a door lock release device (not shown) provided inside the door panel D. is a drive rotation end 41 for lock release. Further, in the cable device 6, both ends 601 and 602 of the outer casing 60 are respectively attached to the first and second brackets 2 and 5 attached to the inside of the door panel D by known means.

Both ends 601 of the outer casing 60
and an inner cable 61 pulled out from 602
The respective retaining shafts 611 at both ends are inserted into the holes 33 of each U-shaped bent piece of the other end 33 of the lock release handle 3.
1 and a locking piece 411 of the drive rotation end 41 for lock release of the lock release lever 4.

Next, the positioning and operation of the door panel lock release device of the present invention will be explained.
A pivot pin P attached to the positioning boss portion 11 of the door opening operation case 1 shown in FIG. 33 into the rectangular hole 20 of the first bracket 2, and then insert the positioning boss part 11 of the door opening operation case 1.
The convex portion 111 is inserted into the notch 2 of the first bracket 2.
1 as shown in FIGS. 3 to 5. Next, as can be seen from FIG. 4, the threaded rod 1 fixed to the boss portion 101 of the door opening operation case 1
02 into the hole 200 of the first bracket 2 from the inside of the door panel D, and then screw the nut 103 onto the threaded rod 102, as shown in FIG. The center of the hole 331 of the rotating end 33 of the lock release handle 3 which is provided so as to fit into the mounting surface 22 of the first bracket 2 to which the end 601 of the outer casing 60 of the cable device 6 is attached. By maintaining the interval C with high precision, the installation is completed with reliable positioning.

Then, the lock release handle 3 shown in FIG.
When both the lock release operation part 32 of the door opening operation case 1 and the anti-slip protrusion 100 of the door opening operation case 1 are picked up with fingers and pushed like castanets, the lock release handle 3 moves around the pivot pin P in the direction of arrow A. Rotate. As a result, the other end 33 of the unlocking handle 3 is rotated clockwise around the pivot pin P, and the hole 331 in each U-shaped bent piece of the other end 33 is
Since one stop shaft 611 at the end of the inner cable 61 is locked, the inner cable 61 is pulled as shown by arrow B in FIG.

Therefore, the drive rotation end 41 for lock release of the lock release lever 4, which is locked to the other stop shaft 611 at the end of the inner cable 61 via the lock piece 411, rotates counterclockwise around the shaft pin 51. The lock release device (not shown) of the door lock connected to one end of the lock release lever 4 is operated to release the lock.

[Effect of idea]

As described above, this invention involves fitting the positioning boss portion of the pivot pin of the door opening operation case, which is formed so that the lock release handle is pivotally supported by the pivot pin, into the notch of the first bracket. Particularly, the first bracket is formed to position the mounting position of the pivot pin with respect to the mounting surface of the first bracket, and the first bracket is fastened to the door panel together with the door opening operation case, Positioning and mounting the door opening operation case on the door panel so as to accurately maintain the distance between the center of the hole at the other end of the lock release handle and the first bracket mounting surface to which the outer casing of the cable device is mounted; The stop shaft of one end of the inner cable of the cable device is engaged with the hole at the pivot end of the lock release handle, and the other end of the inner cable of the cable device is engaged with the drive pivot end of the lock release lever for lock release. This eliminates the need for adjustment man-hours when assembling the door panel lock release device to the door panel, reduces the assembling man-hours and costs, and significantly improves productivity.
