One end of the wire 9 engages with the turn guide 4 and is locked to a wire end case 7f provided on the slider base 7. The other end of the wire 9 engages with the turn guide 5 and is locked to a wire end case portion 7f described later.

Next, the surroundings of the slider base 7 will be described in detail with reference to FIGS. 7 and 8. In the figure, 7a,
Reference numeral 7b denotes a resin slider portion formed on the slider base 7 made of metal by the outsert molding method and slidably engaged with the guide 6. The slider portions 7a, 7
The sliding contact surface of b with the guide 6 is a substantially curved surface in order to reduce the contact area and obtain a smooth sliding contact.

Further, the slider base 7 is provided with holes 7c, 7d and 7e for attaching the door glass 1. Further, the slider base 7 has a wire end case portion 7f.
Are formed. This wire end case portion 7f is
It is a box with an open top surface, and on the side surface is a substantially U-shaped groove 7g,
7h is formed.

Then, both ends of the wire 9 have grooves 7g,
The slide bush 1 is inserted into the wire 7h and has a diameter larger than the widths of the grooves 7g and 7h at both ends of the wire 9 and is capable of contacting the inner wall surface of the wire end case portion 7f.
Nos. 1 and 12 are fixed to prevent them from coming off.

Further, at both ends of the wire 9 of this conventional example,

[0013]

In the window regulator having the above structure, when a force in the vehicle front-rear direction (for example, a force in the arrow F direction) acts on the door glass 1 in FIG. It is transmitted to the guide 6 via the portions 7a and 7b. Then, a compressive force acts on the slider portions 7a, 7b, and a bending moment is generated in the guide 6, which causes a problem that the slider portions 7a, 7b and the guide 6 are deformed.

In order to prevent such deformation of the slider portions 7a, 7b and the guide 6, the slider portions 7a, 7b and the guide 6 are prevented.
Although there is a method of increasing the rigidity of itself, there is a problem that the cost is increased and the weight of the regulator is also increased.

In the window regulator having the above structure, the upper and lower parts of the guide 6 are fixed to the door inner panel, and the slider base 7 is fixed to the door glass 1. The engagement between the guide 6 and the slider base 7 is
This is performed via two slider portions 7a and 7b provided on the slider base 7 and slidably engaged with the guide 6. On the other hand, due to the precision of the parts of the guide 6 and the slider portions 7a, 7b, there is a gap, and a rotating force (swinging force) acts on the side of the door glass 1 that moves up and down, and the wire end case portion 7f
And the guide 6 may interfere with each other.

In the above conventional example, the wire end case portion 7
Since f is made of a soft resin, the sound generated is small even if it interferes with the guide 6, which is not a big problem, but when the wire end case portion 7f is made of a hard metal,
Interference sounds between hard members, that is, between metals, cause a problem of abnormal noise.

Therefore, when the wire end case portion 7f is made of a hard metal, a soft resin is provided between the wire end case portion 7f and the guide 6 in order to avoid generation of an interference sound due to interference with the guide 6. It is necessary to provide a larger gap (for example, about 2 mm to 3 mm) as compared with the case of the wire end case made of metal.

On the other hand, in the window regulator having such a structure, by making the wire 9 and the center of the guide 6 coincide with each other, a rotational force is not generated in the door glass 1 when the door glass 1 is moved up and down, and a smooth glass 1 is obtained. You can get up and down.

However, the wire end case portion 7f
When the door is made of metal, a large gap must be formed between the guide 6 and the guide 6 for the reason described above, so that it is difficult to smoothly raise and lower the door glass 1.

The present invention has been made in view of the above problems, and an object thereof is to provide a window regulator which is low in cost and has improved rigidity. Further, another object of the present invention is to provide a window regulator that can obtain a smooth door glass up and down movement.

[0021]

A window regulator of the present invention which solves the above-mentioned problems is a window regulator which raises and lowers a door glass by using a wire drawn from a drum, and is provided along the ascending and descending direction of the door glass. A guide, a slider base to which the door glass is attached, a slider provided on the slider base and slidably engaged with the guide, an upper guide member provided on an upper portion of the guide, A lower guide member provided in the lower part of the guide, a drum around which the intermediate portion of the wire is wound, and mounted on the slider base, and one end side of the wire engaged with the upper guide is locked. A hard wire end case in which the other end side of the wire engaging with the lower guide is locked. The opposing surfaces of the guide Ya end case, is provided with a contacting supporter in the guide.

When the drum is rotated, one side of the wire is wound on the drum and the other side of the wire is unwound from the drum. By this movement of the wire, the slider base on which the wire is locked moves along the guide, and the door glass moves up and down.

By providing the supporter that abuts the guide on the surface of the wire end case facing the guide, when a force in the front-rear direction acts on the door glass, this force is dispersed between the slider and the wire end case (supporter). And transmitted to the guide.

Therefore, the force applied to the slider and the force applied to the guide are dispersed more than those of the conventional window regulator type, the amount of deformation of the slider and the guide is smaller than the conventional type, and the rigidity of the window regulator is improved at low cost. be able to.

Further, since the supporter is simply provided on the wire end case, the cost is low. Here, the supporter is preferably made of a soft resin from the viewpoint of preventing abnormal noise when the door glass is moved up and down and obtaining a smooth door glass lift.

That is, since the supporter is made of resin, even if the door glass side rotates during up-and-down movement and the wire end case interferes with the guide, the resin supporter hits the guide and the interference noise is small. Further, since the problem of abnormal noise is eliminated, it is possible to bring the wire end end case as close to the guide side as possible, so that the door glass can be smoothly moved up and down.

Further, from the viewpoint that the door glass can be smoothly moved up and down, the resin supporter preferably contains a lubricant. Furthermore, it is desirable that the guide and the contact surface of the supporter are in line contact with each other in order to smoothly raise and lower the door glass.
