2. Description of the Related Art Next, a conventional example will be described with reference to the drawings.
FIG. 5 is an overall configuration diagram of a conventional window regulator, FIG.
5 is an exploded perspective view of a main part of the stopper mechanism in FIG. 5, FIG. 7 is an enlarged view of the wire end case in FIG. 6, and FIG.
(A) is a front view of the stopper rubber in FIG.
7B is a left side view of FIG. 7A, and FIG. 9 is a sectional view taken along the line AA in FIG.

First, the overall construction of the window regulator will be described with reference to FIGS. 5 and 6. In these figures,
Reference numeral 1 is a door glass, 2 is an upper bracket attached to the upper portion inside the door panel, and 3 is a lower bracket attached to the lower portion inside the door panel.

A turn guide 4 is attached to the upper bracket 2.
However, turn guides 5 are rotatably attached to the lower brackets 3, respectively. Reference numeral 6 denotes a guide having an upper end portion attached to the upper bracket 2 and a lower end portion attached to the lower bracket 3 and provided along the vertical direction of the door glass 1.

A slider base 7 is arranged below the door glass 1, and is fixed by three sets of bolts and nuts 8 and 9. Further, the slider base 7 is provided with sliders 10 and 11 slidably fitted to the guide 6.

Further, a wire end case 12 is provided on the slider base 7. Reference numeral 13 is a drum around which an intermediate portion of the wire 14 is wound. This drum 13
Is driven to rotate by a drive motor or the like (not shown).

One end of the wire 14 is engaged with the turn guide 4 and with the wire engaging portion 12a of the wire end case 12 on the slider base 7. The other end of the wire 14 engages with the turn guide 5 and engages with the wire engaging portion 12 a of the wire end case 12.

The stopper mechanism of the conventional window regulator will be described below. A stopper member 15 is fixed to the lower bracket 3. And FIG.
9, the wire end case 12 and the slider base 7 are provided with through holes 12b and 7b (see FIG. 9) formed in a direction substantially orthogonal to the plane of the door glass 1. Then, the through hole 12b is inserted from one opening side and protrudes from the other opening side to form the protruding portion 20.
A stopper rubber 20 is provided so that the side surface of a can contact the stopper member 15.

Further, the wire end case 12 is provided with a stopper support portion 12c which is provided so as to cover the side surface of the protruding portion 20a of the stopper rubber 20 other than the contact portion with the stopper member 15. There is.

The stopper rubber 20 has a retaining portion 20b which is formed at one end portion thereof and abuts against the peripheral edge portion of one opening of the through hole 12b of the wire end case 12, and a protruding portion 2b.
Two retaining projections 20d, 20e extending from the side surface of 0a toward the stopper member 15 and the stopper supporting portion 12c and contacting the peripheral edge of the other opening of the through hole 12b after insertion.
And a fitting portion 20f that fits into the through hole 12b.

Next, the operation of the above configuration will be described. When the drum 13 is rotated, one side of the wire 14 is wound around the drum 8 and the other side of the wire 14 is paid out from the drum 8. By this movement of the wire 14, the slider base 7 on which the wire 14 is locked moves along the guide 6, and the door glass 1 moves up and down.

Further, since the door glass 1 descends and the stopper rubber 20 contacts the stopper member 15, further descending of the door glass 1 is prohibited.

[0013]

However, when the stopper rubber 20 is inserted into the through hole 12b of the wire end case 12 in the stopper mechanism of the window regulator having the above structure, the two stopper portions of the stopper rubber 20 are prevented from coming off. 20d and 20e incline toward the fitting portion 20f, and are further compressed and deformed in the radial direction. After insertion, one of the retaining protrusions 2
0d comes into contact with the peripheral edge of the opening, but the other retaining protrusion 2
Since 0e has the stopper supporting portion 12c, it remains in the through hole 12b as shown in FIG.

On the other hand, the diameter of the through hole 12b must be such a diameter (e) that these two retaining projections 20d and 20e can be inserted, but after insertion, one retaining projection 20e is inserted.
Since it only remains, the fitting portion 20f is loosely fitted in the through hole 12b. Therefore, the stopper support portion 12c has a protrusion amount capable of contacting the protrusion portion 20a of the stopper rubber 20.
The protrusion 12d of (c) is provided, and the stopper rubber 20 is inserted through the through hole
It is designed to be pressed against 2b.

Therefore, the diameter (d = ec) of the protruding portion 20a that abuts on the stopper member 15 is reduced by the amount of the protruding portion 12d, and the impact sound is increased when the stopper member 15 is abutted. There is.

Further, the protrusion 12d must be formed on the stopper support portion 12c of the wire end case 12, which causes a problem that the shape becomes complicated. The present invention has been made in view of the above problems, and an object thereof is to provide a stopper mechanism for a window regulator in which the shape of the stopper support portion is simple and impact noise is reduced.
