Claims (9)

a rotating device comprising a lower rotating member provided on a floor of a vehicle and an upper rotating member provided rotatably about a rotation axis extending substantially vertically from the lower rotating member;
a slide device comprising a lower slide rail coupled to the upper rotating member and an upper slide rail displaceably provided on the lower slide rail;
a seat cushion coupled to the upper slide rail;
a seat back provided on the seat cushion;
a rotation direction restricting device including a restricting wall provided on the upper surface of the upper rotating member and a front stopper projecting downward from the lower surface of the seat cushion;
A vehicle seat in which the rotation direction of the seat cushion is restricted by the contact between the restriction wall and the front stopper when the seat cushion is positioned rearwardly of the rotating device by the slide device. 2. The vehicle seat according to claim 1, wherein the front stopper is arranged inward of the regulation wall in the vehicle width direction. a rotating device comprising a lower rotating member provided on a floor of a vehicle and an upper rotating member provided rotatably about a rotation axis extending substantially vertically from the lower rotating member;

a seat cushion coupled to the upper slide rail;
a seat back provided on the seat cushion;
a rotation direction restricting device including a restriction wall provided on the upper surface of the upper rotating member and a rear stopper projecting downward from the lower surface of the seat cushion;
A vehicle seat in which the rotation direction of the seat cushion is restricted by the abutment of the restriction wall and the rear stopper when the seat cushion is in front of the rotating device by the slide device. 4. The vehicle seat according to claim 3, wherein the rear stopper is arranged inward of the regulation wall in the vehicle width direction. a rotating device comprising a lower rotating member provided on a floor of a vehicle and an upper rotating member provided rotatably about a rotation axis extending substantially vertically from the lower rotating member;
a slide device comprising a lower slide rail coupled to the upper rotating member and an upper slide rail displaceably provided on the lower slide rail;
