Is the jig body. The jig body 21 is formed by connecting a first member 22 made of a metal rod-shaped body having a semicircular cross section and a second member 23 made of a metal strip-shaped body by welding or the like. A bent portion 24 bent in an L shape is provided at an end of the first member 22, and a taper pin 25 protruding in parallel with the first member 22 is provided inside the bent portion 24. ing. Further, a receiving plate 25a is fixed to the side surface of the first member 22 near the taper pin 25, and a hooking portion 26 is formed at one end of the jig body 21. Also, the second member 23
A hooking pin 27 protruding in the direction opposite to the bending direction of the bent portion 24 is provided on the locking pin 27, and a hooking step portion 27 is formed at the base of the hooking pin 27.
a is formed.

On the other hand, as shown in FIG. 3, a first engaging hole 28 into which a taper pin 25 is detachably inserted is formed in the middle of a hinge arm 7 of a hinge mechanism 4 that pivotally supports a trunk lid 10, and a bracket is provided. A hook pin 27 is removably inserted between the hinge shaft 6 of 5 and the fixed portion of the torsion bar 9.
Is provided with a hooking hole 29. Then, the taper pin 25 of the assembly jig 20 is hooked in the first hooking hole 28 of the hinge arm 7, and the hooking pin 27 is hooked in the second hooking hole 29 of the bracket 5, whereby the torsion bar 9 The hinge arm 7 can be rotated in the direction of arrow b against the urging force (direction of arrow a), and the rotation of the hinge arm 7 in the direction of arrow a can be blocked and restrained.

Next, an assembling procedure for assembling the trunk lid 10 to the vehicle body 1 using the assembling jig 20 configured as described above will be described.

First, in the first step, the hinge arm 7 is pivotally supported on the bracket 5 via the hinge shaft 6 and the link 8 is pivotally supported on the hinge arm 7. Next, the torsion bar 9 is hooked between the bracket 5 and the link 6, and the hinge arm 7 is biased in the arrow a direction. Further, the trunk lid 10 is fastened and fixed to the other end of the hinge arm 7 with bolts 11, 11.

After assembling the hinge mechanism 4 to the trunk lid 10 in this manner, the taper pin 25 of the jig body 21 is hooked in the first hooking hole 28 of the hinge arm 7, and the hooking pin 27 of the bracket 5 is locked. By engaging with the retaining hole 29 of No. 2, the hinge arm 7 is resisted against the biasing force of the torsion bar 9 (direction of arrow a).
Is rotated in the direction of arrow b to prevent the hinge arm 7 from rotating in the direction of arrow a. In this case, although the taper pin 25 has the small diameter portion facing upward, the hooking step portion 27a of the hooking pin 27 is hooked on the opening edge of the second hooking hole 29, and the torsion bar 9
Since the urging force (direction of arrow a) is applied, the assembly jig
The 20 does not easily come off the hinge mechanism 4.

The trunk lid 10 to which the hinge mechanism 4 is assembled is clamped by an assembling robot, the hinge mechanism 4 is inserted into the trunk room 2 through the opening of the trunk room 2 of the vehicle body 1, and the bracket 5 of the hinge mechanism 4 is attached to the vehicle body 1. Position on the mounting part 3. The mounting portion 3 is provided with stud bolts 30 and 30 projecting therefrom, and the mounting holes formed in the bracket 5 are fitted into the stud bolts 30 and 30. In this state, the stud bolts 30, 30 are screwed into the nuts 31, 31, and the nuts 31, 31 are tightened by a nut runner or the like, so that the trunk lid 10 is fixed to the mounting portion 3 via the hinge mechanism 4.

After the trunk lid 10 is assembled to the vehicle body 1, when the trunk lid 10 is closed, the hinge arm 7 rotates about the hinge shaft 6 and the first hook hole 28 rotates while drawing an arcuate path c. To do. In addition, the jig main body 21 has a taper pin 25 centered on the latch pin 27 as the hinge arm 7 rotates.
Rotates while drawing an arc locus d. Therefore, when the first hooking hole 28 provided in the hinge arm 7 reaches the point e of the arc locus c as the trunk lid 10 is closed,
The taper pin 25 draws a circular arc path d larger than that of the first hooking hole 28, so that the taper pin 25 comes out of the first hooking hole 28. When the taper pin 25 comes out of the first hook hole 28, the assembly jig 20 moves to the hook pin 27.
The hooking pin 27 comes out of the second hooking hole 29, and the assembling jig 20 moves from the hinge mechanism 4 together with the vibration caused by the shock when the trunk lid 10 is closed. It falls off and falls inside the luggage compartment 2. In other words, after assembling the trunk lid 10 to the vehicle body 1,
The assembly jig 20 can be removed from the hinge mechanism 4 simply by closing the trunk lid 10.

As described above, according to the present invention, one end of the hinge arm is fixed to the trunk lid, and the link and the trunk lid are biased in the opening direction between the hinge arm and the bracket. While a hinge mechanism is constructed by providing a torsion bar, one end of the jig body has a latch pin that is detachably latched to the bracket, and the other end has a latch portion that is detachably latched to the hinge arm. Provided with an assembling jig, the engaging pin of the assembling jig is hooked to the bracket, and the hooking portion is hooked to the hinge arm to restrain the torsion bar against the biasing force of the torsion bar. The hinge mechanism assembled to the trunk lid is inserted into the interior of the trunk room, and the bracket of the link mechanism is attached to the mounting part of the vehicle body to attach the trunk lid.
