Reference numeral 30 denotes a roller guide plate. The roller guide plate 30 is connected to one side of the base wall 27 of the upper rail 23 and the flange 2 of the lower rail 22.
6 and at least two holes 31, 32
(In this embodiment, two places) are provided between the first roller guide part 33 having a perforation, the other side of the base wall of the upper rail 23, and the flange part 26 'of the lower rail. Holes 34, 35 (two in this embodiment)
A second roller guide portion 36 having a hole formed therein, side walls 25 and 25 'of the lower rail 22, and a base wall portion 2 of the lower rail 22.
4, each of which is bent so as to face each other, and includes a bridging portion 37 that bridges the first roller guide portion 33 and the second roller guide portion 36.

Rollers 38, 39, 40, 41 are provided in the holes 31, 32, 34, 35 so as to roll, and the rollers 38, 39 are formed between the flange 26 of the lower rail 22 and the base rail 23. Rollers 40,
41 abuts against the lower rail flange 26 'and the base wall 27 of the upper rail 23, respectively.
Of the lower rail 22 is smoothened.

Reference numeral 42 denotes a bridging portion 37 of the roller guide plate 30, a base wall portion 27 of the upper rail 23, and a roller 3.
8, 39, 40, and 41 are threaded rods disposed in the space formed by them.

The flanges 26, 2 of the lower rail 22

The sliders 43 and 44 made of a low friction material are mounted on the sliders 9 and 29 'and the side walls 28 and 28'.

According to the above configuration, the rollers 38 and 39 are connected to the first roller guide portion 33 of the roller guide plate 30.
The rollers 40 and 41 are provided on the second roller guide portion 36 of the roller guide plate 30,
1, the screw rod 42 is provided on the bridge portion 37 of the roller guide plate 30, the upper rail 37, the base wall portion 27 of the upper rail 23, and the rollers 38, 39, 40, and 41. Since the screw rod 42 and the rollers 38, 39, 40, and 4 are disposed in the space to be formed.
1 can be arranged side by side on substantially the same level, so that the seat track section height can be reduced. That is, in FIG. 4 showing the conventional example, it is possible to reduce the cross-sectional shape of the sheet track about the diameter X of the roller 11.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the lower rail 22 is described as a first rail, and the upper rail 23 is described as a second rail. However, conversely, the first rail is described as the upper rail 23, and the second rail is described as the lower rail 22. Is also good.

[0022]

As described above, according to the present invention, the roller is divided and disposed on both sides in the cross section of the seat track, and the threaded rod is connected to the bridge of the roller guide plate, the base wall of the upper rail, and the like. In addition, by arranging them in the space formed by the rollers, it is possible to realize a seat track having a reduced sectional height.
