And a regulating recess 30e for regulating upward movement.

When the pair of positioning projections 30d are inserted into the pair of positioning holes 23b, the wire hooking jig 3
0 is rotatably coupled to the first pulley member 23 together with the first pulley member 23. In this state, the boundary 30f between the wire support surface 30a and the guide inclined surface 30b is connected to the pair of wire hooks on the guide pulley 18 side. The position is determined so as to correspond to the notch 23a as shown in FIG.
Therefore, when the wire hooking jig 30 rotates in the direction of arrow A in FIG. 4 together with the guide pulley 18 in a state where the wire 12 before being wound around the guide pulley 18 is wound,
After the wire 12 is moved downward along the guide inclined surface 30b, and the wire 12 is engaged with one of the pair of wire-cut notches 23a that are rotated, the wire groove 23 is gradually moved.
wrap around d.

A jig-side ratchet tooth 30c is formed at the upper center of the wire hanging jig 30. The jig-side ratchet teeth 30c are meshed with the rotating shaft-side ratchet teeth 33a formed at the distal end of the swaging rotary shaft 33 that constitutes the riveting device 31, and receive the rotational force of the swaging rotary shaft 33 so as to receive the jig. Rotate the entire 30. The riveting device 31 also has a caulking bar 32 for caulking the distal end portion 26c of the caulking rotary shaft 26 protruding downward from the guide bracket 14. The tip of the caulking rod 32 is formed in a substantially hemispherical shape, and the rotating tip 26
c and crimp it into a hemispherical shape as shown in FIG. 5 (round caulking).

Therefore, the above-mentioned window glass raising / lowering mechanism 9 can be assembled as follows. First, in the guide bracket 14 fixed to the upper part of the guide rail 10, as shown in FIG. 1, the first pulley member 23 is superimposed on the second pulley member 25 with the guide projection 25a facing upward, and the guide pulley 18 Further, the caulking rotary shaft 26 is passed through the rotation support hole 23c and the rotation support hole 25b, and then is inserted into the rotation support hole 14a.
8 is rotatably supported on the guide bracket 14.

Then, the wire hooking jig 30 having the wire 12 before being wound around the guide pulley 18 with an appropriate tension is applied to the pair of positioning projections 30 d by the pair of first pulley members 23. Positioning hole 23b
At the same time, caulking the regulating recess 30e and rotating the shaft 26
By being fitted to the head 26 a of the first pulley member 23. Thereby, the wire hanging jig 30
Is connected to the guide pulley 18 in a state where a pair of boundary portions 30f as shown in FIG. 4 correspond to the pair of wire hooking notches 23a.

Furthermore, the wire hooking jig 3 in this connected state
0 and the upper and lower sides of the guide pulley 18, the ratchet teeth 33a of the rotating shaft 33 of the riveting device 31 are meshed with the ratchet teeth 30c of the jig side, and the riveting device 31 is The tip of the caulking rod 32 is brought into contact.

In this state, the riveting device 3
When 1 is driven, the rotation of the caulking rotation shaft 33 causes the wire hooking jig 30 to start rotating in the direction of the arrow A in FIGS. Then, as shown in FIG. 4, the wire 12 wound around the wire supporting surface 30a of the wire hanging jig 30 before being wound around the guide pulley 18 gradually winds around the guiding inclined surface 30b, and the guiding inclined surface 30b Is moved down by As a result, a part of the wire 12 corresponding to the one wire hooking notch 23a is
It wraps around a. Then, the wire 12 is gradually wound around the wire groove 23d by the further rotation of the guide pulley 18, and is in the state shown in FIGS. Wire 1
2 further rotates the guide pulley 18 in the same direction, thereby maintaining the predetermined tension force.
It is wound around the wire groove 23d of the pulley member 23.

At the time of the rotation of the wire hooking jig 30 and the guide pulley 18 by the riveting device 31, the swaging rotary shaft 26, which is pressed down through the restricting recess 30 e of the wire hooking jig 30, has its head 26 a swaged by the swaging rod 32. Is rotated in a state in which it is pressed against the tip of the lens (see FIG. 5). Thereby, the caulking rotation shaft 26 is supported so as to be retained, and the guide pulley 18 can be supported rotatably with respect to the guide bracket 14. And this assembling process is performed by the guide bracket 15
The same operation is performed when the guide pulley 19 is mounted on the side.

As described above, according to the present embodiment, by using the wire hooking jig 30 and the riveting device 31, the step of winding the wire 12 around the guide pulley 18, which has been conventionally performed separately, and the swaging rotary shaft The step of caulking the tip 26c of the 26 can be performed at the same time, so that the number of work steps can be reduced. Furthermore, unlike the related art, the wire itself does not exert a load due to the tension force of the wire 12, so that the strength of the assembled wire 12 is not deteriorated and the quality is not deteriorated.

[0023]

As described above, according to the present invention, the step of winding the wire around the guide pulley and the step of swaging the rotating shaft, which have been conventionally performed separately, are simultaneously performed.
Work man-hours can be reduced. Further, the wire itself does not exert a load due to the tension force of the wire, so that the strength of the wire after assembly is not impaired, and the inconvenience of quality deterioration can be surely eliminated.
