PROBLEM TO BE SOLVED: To efficiently and effectively suppress rolling of a seat when a vehicle makes a turn. SOLUTION: In this seat system 10, a first roller 110L and a second roller 120L having lower rigidity than that of the first roller 110L are made to abut on bottom part and one side part of a fixed part 15L, respectively. An angleθ<SB>1</SB>formed by a load line L2 for connecting an abutting point PL of the first roller 110L and a center of gravity G of a seat assembly and a reference line L1 elongated to a vertically lower side from the center of gravity G is set to be larger than an angleθ<SB>2</SB>formed by a straight line elongated in a first direction to be a normal line direction stood on a bottom surface of a rail part 130L supporting the first roller 110L. The second roller 120L is displaced by receiving component force of a second direction to be a direction orthogonal to the first direction to suppress roll of the seat, of resultant force acting on the abutting point PL in the direction of the load line L2 when turning the vehicle. According to the displacement, the seat assembly 11 including the fixed part 15L is displaced in the direction to suppress roll of the seat. COPYRIGHT: (C)2007,JPO&INPIT
