Further, a third seat 4 as a “rear seat” is installed on the rear side of the vehicle interior. A second seat 15 as a “slide seat” is provided between the front seat 1 and the third seat 4.

The third seat 4 includes a seat cushion 5 and a seat back 6. The seat back 6 is attached to the rear of the seat cushion 5 so as to be foldable forward, and the seat back 6 overlaps the seat cushion 5 in a folded state. A recess 7 is formed in the floor 2 below the third seat 4, and is normally fixed so as to straddle the recess 7 by a mounting bracket (not shown). Then, the mounting bracket is removed, the third seat 4 is folded, and the seat cushion 5 can be stored in the recess 7 in an inverted state with the back surface of the seat cushion 5 facing upward. In the stored state, the back surface of the seat cushion 5 has the same height as the floor 2. On the floor 2 behind the recess 7,
A U-shaped floor striker 8 is fixed.

On the floor 2 between the front seat 1 and the third seat 4, a pair of left and right rails 9 are provided along the front-rear direction. The rail 2 has a cross-sectional shape having an opening on the upper surface, and a runner 1 having a substantially inverted T-shape therein.
The lower part of 0 is slidably engaged. Runner 10
Rollers 10 are provided before and after the rails so that they can move smoothly in the rails 9. The runner 10 has a horizontal upper surface, and an upward flange 12 is formed at an outer end in the vehicle width direction, and an outward auxiliary rail 13 is fixed thereto. A runner striker 14 is provided at the rear end of the runner 10.
Is provided.

On the other hand, a pair of left and right legs 16 each extending in the front-rear direction are fixed to the lower surface of the second seat 15,
The leg 16 is mounted on the upper surface of the runner 10. Therefore, the second seat 15 is connected to the leg 16
And can be slid back and forth on the runner 10 via the. The runner 10 is fixed to the rail 9 by an interlock mechanism (not shown) provided on the runner 10 engaging the rail 9. A cushion rubber 17 is provided at the front end of the leg 16, and a lock portion 18 that can be engaged with the run striker 14 is provided at the rear end. The leg 16 is fixed to the runner 10 by engaging the lock portion 18 with the runner striker 14. Incidentally, the engagement between the lock portion 18 and the run striker 14 can be released by operating the lever 19.

A bracket 20 is attached to the front end of the leg 16 on the outer side in the vehicle width direction at a predetermined interval from the leg 16. A slider 21 slidably engaged with the auxiliary rail 13 is rotatably supported by a bracket 20 via a shaft 22. At the other end of the shaft 22, a return spring 23 is provided as "urging means", and applies a urging force in a direction of lifting the rear portion of the second seat 15 upward.

Next, the operation of the second sheet 15 will be described. Normally, as shown in FIG. 1, the second seat 15 is slidable back and forth between the front seat 1 and the third seat 4, and the second seat 15 can be fixed at a desired position by an interlock mechanism (not shown). It has become. The weight of the second seat 15 is determined by the upper surface of the runner 10 and the runner striker 1 via the leg 16.
