2. Description of the Related Art In a window regulator device, a sash frame having a glass run channel and a guide rail are individually fixed to an inner panel, and a carrier plate slidably supported by the fixed guide rail. A wire type that supports the center of the lower end of the glass and slides the carrier plate with a wire driven by a driving means such as a drive motor or lever, and raises and lowers the glass while guiding both ends of the glass with a sash frame is there. Japanese Patent Application Laid-Open No. Sho 64-71986 discloses a slider plate slidably supported by a pair of guide rails and driven by a wire disposed in the guide rail.
There has been proposed a wire type window regulator device in which holders provided at glass ends are connected and integrated.

[0003]

In the above-mentioned wire type window regulator device, the carrier plate supports the center of the lower end of the glass, so that the glass easily swings around this supporting portion in the direction intersecting the vertical direction. It is difficult to keep the distance between the glass and the sash constant. If the distance between the two cannot be maintained, the glass sash comes into contact with the sash due to the swinging of the glass caused by the ascending and descending operation, and the sliding resistance and the sliding contact noise increase. Since a glass run channel is usually inserted in the sash, the swing of the glass is
The glass run channel is brought into contact with the glass end to cause abrasion of the run channel and a change in sliding resistance. As a result, there is a high possibility that poor elevation of the glass occurs. In addition, with this configuration, generation of rattling noise and rubbing noise between the carrier plate and the guide rail that slidably supports the carrier plate may be considered.

In the window regulator device proposed in Japanese Patent Application Laid-Open No. Sho 64-71986, since the wire for driving the slider plate is arranged in the guide rail, the wire bites into the glass or the holder during the elevating operation of the glass and moves up and down. There is a possibility that it may be defective or hinder smooth glass lifting / lowering operation. SUMMARY OF THE INVENTION It is an object of the present invention to provide a window regulator device that is quiet, has good durability, and can perform a stable raising and lowering operation of glass.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a glass member guided at both ends into a pair of sash portions arranged in parallel to face each other is attached to a wire stretched in connection with driving means. The wire is stretched in parallel with the sash portion by two pulleys and pressed against the sash portion on the line connecting the pulley with the mounting member, and the mounting member is attached to the sash. It is characterized by being biased toward.

With such a configuration, the mounting member is
Since the wire which is stretched in parallel with the sash portion by the notch pulley and pressed on the opposite side of the sash portion with respect to the line connecting the pulley with the mounting member is urged toward the sash portion at the time of raising and lowering the glass, The swing of the glass centering on the glass support part due to the elevating operation can be suppressed. Further, since the wire is stretched in parallel with the sash portion, the risk of biting between the sash portion and the glass at the time of raising and lowering the glass is reduced.

A and 2B are urged by the outer surfaces 2Aa and 2Ba,
The swing in the direction of arrow C during the elevating operation is restricted. Therefore, since the glass 3 moves up and down while maintaining the parallelism, the distance a between the outer peripheral edges 3A1 and 3B1 of the glass 3 and the bottoms 70a and 70b of the glass run channel 70 is kept constant. Therefore, contact between the two is eliminated, and sliding resistance, sliding contact noise, and abrasion of the glass run channel 70 can be prevented.

Glass holders 62 and 63 and wire holder 6
0 and 61 are detachable, the regulator mechanism 4
The glass 3 can be attached to the door sash frame 2 individually, so that the glass 3 can be attached easily.

Also, if the drive motor 45B over-rotates,
If any overload is applied to the wire 44, the wire 44 may temporarily extend and become loose. In such a state, as shown in FIG. 9, the bracket 46 supporting the pulley 43 is pulled downward from the solid line position by a two-dot chain line by the tension spring 50.
Therefore, the position of the pulley 43 is displaced, and the slack of the wire 44 is efficiently absorbed, so that it is possible to prevent biting due to the slack of the wire 44b and lifting failure due to detachment from the pulley.

The other ends 60b, 61b of the wire holders 60, 61 in this embodiment are formed in an L-shaped cross section so as to abut the outer surfaces 2Aa, 2Ab and the outer surfaces 2Ba, 2Bb of the side sashes 2A, 2B, respectively.
