Along the lines 31 and 31, the side glass G is moved up and down.

The lower portion of the side glass G is supported by a carrier plate 2, and on the back surface of the carrier plate 2, first, second and second guides for movably guiding the carrier plate 2 along rails 11, 21 and 31. The third guide mechanisms 10, 20 and 30 are configured, and a wire 6 stretched between the upper and lower guide pulleys 3 and 4 and the drive pulley 5 on the base 1 is connected by a connecting member 7. . The driving pulley 5 is connected to the motor 8
As a result, the carrier plate 2 moves up and down together with the side glass G via the wire 6. Hereinafter, the first, second, and third guide mechanisms 10, 20, and 30 will be described separately. The first and second guide mechanisms 30 are the guide mechanisms of the present invention.

[First Guide Mechanism 10] As shown in FIG. 2, a rail 11 of the guide mechanism 10 is folded in a substantially inverted V-shaped cross section toward the rear side (left side in FIG. 2) of the vehicle body on the base 1. It is curved. In FIG. 2, the lower part in the figure is the vehicle interior, and the upper part is the vehicle exterior. As shown in FIGS. 3 to 5, a joint shaft 12 having a spherical head 12A is provided on a side 2A of the carrier plate 2 on the rear side of the vehicle body (hereinafter, simply referred to as "rear side").
A spherical seat 13A of a slider 13 made of synthetic resin is fitted to the head 12A so as to be rotatable in all directions. The upper and lower surfaces of the head 12A of the shaft 12 in FIG. 5 are flat, and a metal bracket 14 for reinforcement is attached to the back surface of the slider 13. The spherical seat 13A of the slider 13 has slits 13B, 13B.
A roller 15 made of a synthetic resin is rotatably fitted in a groove 13C formed in the outer peripheral portion thereof. The outer peripheral surface of the roller 15 is formed in a substantially arc-shaped cross section as shown in FIG. Further, the slider 13 is formed with two claw portions 13D, 13D facing the outer peripheral surface of the roller 15 at a predetermined interval and in contact with the bent portion 14 of the bracket 14. As shown in FIG. 3, a substantially reverse V
Sliding contact surfaces 13E and 13F in the shape of a letter are formed.

Then, as shown in FIG.
Of the rail 11 between the claw portions 13D, 13D of the
, The slider 13 is movably guided along the rail 11. That is, the roller 1
5 is pressed against the left and right inner surfaces (lower left and right surfaces in FIG. 3) of the rail 11 whose outer peripheral surface forms a substantially inverted V-shape.
The third sliding contact surfaces 13E and 13F are pressed against the left and right outer surfaces (upper surfaces on the left and right in FIG. 3) of the rail 11 having a substantially inverted V-shape. Then, the relative displacement between the rail 11 and the slider 13 in the left-right direction (the front-rear direction of the vehicle body) in FIG. 3 and the up-down direction (the left-right direction of the vehicle body) in FIG. The slider 13 is movably guided along the direction in which the slider 11 extends (the direction of the front and back of the paper in FIG. 3). When the slider 13 moves, the roller 15 rolls. Further, the carrier plate 2 is rotatably connected to the slider 13 along the peripheral surface of the head 12A of the shaft 12 in all directions.

"Second Guide Mechanism 20" As shown in FIG. 2, the rail 21 of the guide mechanism 20 is folded in a substantially inverted V-shaped cross section on the front side (the right side in FIG. 2) of the vehicle body on the base 1. It is curved. And
As shown in FIGS. 6 and 7, the carrier plate 2 is formed by the shaft 12, the slider 13, the bracket 14, and the roller 15 similar to the first guide mechanism 20 described above.
Front side of the vehicle body (hereinafter simply referred to as "front side")
) Is guided movably along the rail 21.

However, in this second guide mechanism 20, the shaft 12 and its head 12A are formed separately, and the head 12A is It is fitted so as to be displaceable in the direction (the front-rear direction of the vehicle body). The tip of the shaft 12 has a non-circular cross section, and the head 12A is prevented from rotating with respect to the tip. Therefore, the carrier plate 2 is connected to the slider 13 so as to be rotatable in all directions along the peripheral surface of the head 12A and to be displaceable in the front-rear direction of the vehicle body.

"Third Guide Mechanism 30" The rail 31 of the guide mechanism 30 is mounted on the base 1 so as to extend vertically between the rails 11 and 21. As shown in the figure, a central guide portion 31A having a substantially inverted V-shaped cross section is formed at the center thereof, and both side portions 31B, 3 are formed.
1C is bent outward. As shown in FIG. 8, a joint shaft 32 having a substantially spherical head 32A is implanted in the center of the carrier plate 2.
, A spherical seat portion 33A of a slider 33 made of a synthetic resin is rotatably fitted in all directions. The front end of the head 12A of the shaft 12 is flat, a metal bracket 34 for reinforcement is attached to the back surface of the slider 33, and an annular ring between the bracket 34 and the carrier plate 2 as shown in FIG. A cushion rubber 35 is interposed. On both sides of the slider 33, both sides 3 of the rail 31
A sliding contact surface portion 33 slidingly contacting the lower surfaces of 1B and 31C in FIG.
A and 33B are formed in a substantially C-shaped cross section.

The slider 33 accommodates two substantially gourd-shaped rollers 36 as shown in FIG. As shown in FIG. 10, the central recess 36A of the roller 36 is sandwiched between the central guide 31A of the rail 31 and the protrusion 33C of the slider 33, and the recess 36A
Are pressed against the left and right outer surfaces (upper surfaces on the left and right in FIG. 10) of the central guide portion 31A having a substantially inverted V shape. The tip of the projection 33C has a substantially semicircular cross section as shown in FIGS. Both ends 36B and 36C of the roller 36 have a spherical shape centered on the center point P (see FIG. 10), and both end portions 36B and 36C have a spherical shape centered on the point P similarly. Spherical seat 33 of slider 33
D and 33E are rotatably held in all directions.
Therefore, the roller 36 is rotatable about its rotation axis O (see FIG. 10) and its both ends 36B, 36B.
It is swingable in all directions around the point P so as to follow the spherical shapes of C and the spherical seats 33D and 33E.

The slider 33 is movably guided along the rail 31 with the rolling and sliding of the roller 36. The slider 33 is moved in accordance with the relative displacement between the carrier plate 2 and the rail 31. , Cushion rubber 3
5 is accompanied by the elastic deformation of the
Swings along the peripheral surface of the head 32A of the
The rotation axis 0 of 6 is oscillated about the point P.

The carrier plate 2 is guided by the first, second and third guide mechanisms 10, 20 and 30 so as to be able to move up and down with respect to the rails 11, 21 and 31.

The rails 11, 21, and 31
All have an open cross-sectional shape in which the left and right sides open outward. That is, each of the rails 11 and 21 has a substantially inverted V-shaped cross-section in which both sides open outwardly.
Numeral 1 has a substantially W-shaped cross section as a whole, a substantially inverted V-shaped cross section in which a central guide portion 31A is opened outward, and both side portions 31B and 31C are bent outward. The rails 11, 21, and 31 having such an open cross section have
Compared to conventional rails with a substantially C-shaped pseudo-closed cross section,
By means of a press or the like, molding can be performed easily and with high precision. As a result, the lifting and lowering of the window glass G becomes smooth.

Further, the locus of movement of the carrier plate 2 can be freely set three-dimensionally in accordance with the shapes of the rails 11, 21 and 31.
In the fully closed state, the window glass G is displaced so as to sufficiently fall down on the vehicle body side, thereby making it possible to securely close the window glass.

[0020]

As described above, the guide mechanism of the present invention rotatably supports a roller on one side of a pair of opposing portions formed integrally with a slider, and on the other side of the pair of opposing portions. Since the sliding contact surface is formed and each of the rollers and the sliding contact surface is pressed against the guide surface on the front surface side and the back surface side of the guide rail, the configuration can be simplified with a small number of parts.
