4, 14a will be required.

Furthermore, the pair of outer tubes 10, 10a
As shown in FIG. 2, a fitting hole 15 is formed in the bent portion 14 of the upper bracket 8, and the bracket 8 is fitted and supported in the fitting hole 15 via a collar 16.
A locking ring 17 is fixed to one end of the outer tube 10 and is locked to the collar 16.
As another example, as shown in FIG. 3, a U-shaped notch 15a with one end open is formed in the bent part 14a of the lower bracket 8a, and the outer tube 10a is inserted into this notch 15a. A fixing metal fitting 18 is fixed to the bracket 8a so that one end thereof is fitted with a locking ring 17a fixed thereto, and the locking ring 17a is not removed from the open side of the notch 15a. This covers the upper side of the locking ring 17a. In this way, the outer tube 10,1
In order to support one end of 0a to the brackets 8, 8a, a collar 16, locking rings 17, 17a, and fixing metal fittings 18 are required, which increases the number of parts and requires separate parts. There was a problem that the workability for assembly deteriorated.

6 is located within the guide rail 21, and a portion thereof is connected to the glass bracket 23. Then, both ends of the wire 26 that has passed around the pulleys 24, 24a are appropriately separated from the guide rail 21 and guided toward a drum 27 as an actuator that is bonded to a door panel or a vehicle body panel. It is wound around and connected to the drum 27. And the drum 27
By manually or automatically rotating the wire 26, the window glass 22 is moved up and down together with the glass bracket 23. 28, 28a are the pulleys 24, 24a
An outer tube is fitted to the outer periphery of the wire 26 disposed between the drum 27 and the drum 27 so as to be relatively movable, and the wire 26 is tensioned by the outer tubes 28 and 28a. By the way, in this embodiment, the guide brackets 29, 29a provided separately from the pulleys 24, 24a are attached to the guide rails 21 of the pulleys 24, 24a used as the guide members. It is rotatably pivotally mounted to the mounting shafts 25, 25a adjacent to the sides. The guide bracket 2
As shown in FIGS. 6 to 8, 9 and 29a are integrally connected to the outer tube 2 from a base 31 having a mounting hole 30 through which the mounting shafts 25 and 25a are inserted.
A fitting portion 32 is formed to fit one end portion (guide rail 21 side) of the pulleys 24, 28a, and the center axis of the fitting portion 32 is formed in a tangential direction to the circumferential groove 33 of the pulleys 24, 24a. has been done. Further, a notch 34 is formed in the side wall of the fitting 32, and the wire 26 is inserted into the fitting 32 through this notch 34. On the other hand, the drum 27 is attached to a base plate 35 shown in FIG. 9 which is attached to a door panel or a vehicle body panel.
It is rotatably supported by the outer tube 2.
Beat portions 36, 36a having an inverted U-shaped cross section as shown in FIG. 10 for attaching 8, 28a are formed on the base plate 35, and tube holders 37, 37a as shown in FIGS. 11, 12 are provided. It is being The bead portions 36 and 36a are formed in advance in the direction in which the outer tubes 28 and 28a are disposed, and are provided in the tangential direction of the drum 27. Further, the tube holders 37, 37a include a mounting portion 38 inserted into the bead portions 36, 36a, and an outer tube 28, 2 integrally formed from the mounting portion 38.
A fitting part 39 into which the other end (drum 27 side) of 8a is fitted is provided, and a notch 40 for inserting the wire 26 is formed in the side wall of this fitting part 39.

With the above configuration, the outer tubes 28, 28
When installing a, first connect the wire 26 to the guide brackets 29, 29a and the tube holder 3.
The outer tubes 28, 28a are inserted through the notches 34, 40 into the fitting parts 32, 39 formed on the guide brackets 29, 37a, respectively, and one end of the outer tubes 28, 28a is inserted into the fitting part 32 of the guide brackets 29, 29a. At the same time, the outer tubes 28, 28a
After inserting the coil springs 41 and 41a in advance, the other end is inserted into the fitting part 39 of the tube holder 37 and 37a, and then the tube holder 3
The mounting portion 38 of 7, 37a is attached to the base plate 3.
This is done by inserting it into the beat parts 36, 36a of No. 5. In addition, the outer tube 28, 2

being pushed in the direction. Therefore, in the wind regulator 20 of this embodiment, when attaching the outer tubes 28, 28a to the guide rail 21 side, one end of the outer tubes 28, 28a is simply inserted into the guide brackets 29, 29a. The outer tubes 28, 28a are locked by simply being inserted into the joint portion 32, and the workability for assembling the outer tubes 28, 28a is significantly simplified. Further, the necessary members for attaching one end of the outer tubes 28, 28a to the guide rail 21 side are the guide brackets 29, 29a.
This greatly reduces the number of parts.

13 to 15 show another embodiment, in which a protrusion 50 is formed on the guide rail 21 side end surface of the guide brackets 29, 29a, and a recess 51 into which the protrusion 50 fits is formed in the guide rail 21. However, by fitting the protrusion 50 into the recess 51, the guide brackets 29, 29a are positioned. That is, the wire 26 is connected to the pulley 2 depending on the mounting position of the drum 27.
The direction to be guided from 4, 24a is determined. Therefore, the direction in which the outer tubes 28, 28a fitted to the wire 26 are arranged is also necessarily determined. In this embodiment, the formation position of the recess 51 is set in advance so that the outer tubes 28, 28a are arranged in a determined direction, and when the guide brackets 29, 29a are assembled, the protrusion 50 is The fitting portions 32 of the guide brackets 29, 29a are fixed in a predetermined direction simply by fitting the guide brackets 29, 29a into the recesses 51. In this embodiment, the protrusion 50 is attached to the guide bracket 2.
9 and 29a, and the recess 51 is formed at the same time when the guide rail 21 is pressed, so that no special processing work is required.

Effects of the Invention As explained above, in the wind regulator of the present invention, the guide members provided at both ends of the guide rail are connected to a pulley and a guide guide provided coaxially and rotatably relative to the pulley. Since the outer tube is locked by fitting one end of the outer tube to the fitting portion of the guide, the work of assembling the outer tube to the guide rail side is significantly simplified, and At this time, the outer tube is mounted only using the guide bracket, which has the excellent effect of making it possible to significantly reduce the number of parts, simplifying the assembly work, and reducing costs. play.
