The upper part of the passage 9 is cut out 9a and opened to the groove part 2b, and the passage 9 and the groove 2 communicate with each other at the cutout part 9a. The guide rail 1 described above has the same cross section over its entire length.

In the above guide rail 1, the angle θ between the rear part a and the side piece 3 is a right angle so that the groove 2 is perpendicular to the axis N in the width direction as shown in FIG. The seat is gradually twisted forward so as to be inclined diagonally downward on the side surface of the seat, and the angle is set to θ ₁ smaller than 90° at the middle part b as shown in Fig. 6.
Furthermore, at the front part c, the angle is set to θ ₂ , which is smaller than θ ₁ , as shown in FIG. As a result, the groove 2 is twisted and inclined laterally and diagonally downward, and the twist angle gradually increases from the rear to the front.

A pair of symmetrical guide rails A and B are prepared for the guide rails 1 described above, and each guide rail A and B is a console provided in the front-rear direction at the center of the seat portion 18a of the left and right seats 18 of the vehicle in the vehicle width direction. Box 10
The seat portion 1 of the seat 18 is arranged in the front-rear direction on the left and right sides of the
The seat can be moved forward and backward to adjust its position in the front and back direction using the top rail 19 provided below 8a and the lower rail 20 on the floor side. 11 and an upright stay 12 supported on the inner surface of the console box 10, and the other B is similarly supported. Rails A and B are arranged so that their respective grooves 2 face symmetrically outward, that is, toward the side of the seat, and as mentioned above, rails A and B are arranged so that the grooves run diagonally downward from the rear to the front. The tunnel 11 is twisted so as to be inclined, and the upper and both sides of the tunnel 11 including the rails A and B are covered with a console box 10.
Parts of the rails A and B bulge upward symmetrically in a duct-like manner 10a, 10a, and bulges 10a, 10b are formed.
Openings 10b extending in the front-rear direction are formed at the top. Due to the twisting of rails A and B, each groove 2 is vertical in the rear part as shown in Fig. 2, and each groove 2 in the front part opens symmetrically to the outside, that is, diagonally downward on the side of the seat as shown in Fig. 3. . The slider 13 is slidably fitted into the grooves 2 of the rails A and B, and the slider 1
The support part 13a of the belt guide arm 14 is fixed to the supporting part 13a of the console box 1, and the support part 13a of the belt guide arm 14 is fixed to the support part 13a of the console box 1.
