Is separated from the lock lever 29b of the lock mechanism 29 to allow the rotation of the lock lever 29b, and the release handle 29a can be released. At the same time as the seat S is turned forward, the striker 4 of the rotation lock mechanism 40 is turned off.
The engagement of the hook 8 with the hook 45 locks the turntable 30, and the rotation of the sheet S is restricted.

Thereafter, the release handle 2 of the lock mechanism 29
9a, the locked state of the seat track 25 is released, the seat S is moved inward to the innermost position indicated by S1 in FIG. 10B, and then the release handle 19a of the lock mechanism 19 is operated. The locked state of the seat track 15 is released, and the seat S is set to the rearmost retreat position indicated by reference numeral S in FIG. In this state, the occupant steps down on the floor C from the footrest 32, and the footrest 32 is pushed into the storage position.

As described above, in the vehicle seat apparatus, when the occupant gets on the vehicle, the seat S is moved forward from the normal use position, and then moved outward.
Finally, by rotating the seat S, the seat S can be positioned at an outward position where the ride is easy. After the occupant is seated on the seat S, the seat S can be positioned in the normal use position by performing the above-described operations in reverse order. As a result, the seat S can be located at an outward position where it is easy to get off the vehicle.

In each of the above-described operations of the seat apparatus, each operation is performed by the operation of each of the lock mechanisms 19, 29, 40, and 60 so that the operations do not overlap at the same time. In particular, since the movement in the left-right direction is restricted during the rotation operation of the seat S, there is no possibility that the seat S will move toward the vehicle interior during the rotation due to an erroneous operation. In the seat device,
Since the seat S is locked at the rotational operation position, the seat S does not rotate when the occupant sits on the seat S or separates from the seat S, so that getting on and off is extremely easy.
