PROBLEM TO BE SOLVED: To provide a vehicle seat capable of enlarging the vertical strokes of a load receiving member such as a plane spring in a seat with a displacement sensor. SOLUTION: In this vehicle seat, the plane spring 15 as a load receiving member is provided in a seat frame 14, and it is configured to be supported through supporting springs 32a-32f provided between the seat frame 14 and itself. In the seat frame 14, displacement sensors 20a-20d with a pulley 34 are provided. The rotation center of the pulley 34 is positioned lower than the plane spring 15. A wire rope 35 is wound around the pulley 34 as a pulling member, and it is pulled out from the bottom side of the pulley 34 obliquely upward and connected to the plane spring 15. The plane spring 15 moves downward as a load from above increases, and at that time the pulley 34 is rotated in the winding direction of the wire rope 35. COPYRIGHT: (C)2005,JPO&NCIPI
