Abstract
It is one object of this invention to provide a technique that is effective in diminishing the range of fluctuation of a load applied to a drive source when a seat main body in a vehicle seat moving apparatus is moved between a raised position and a lowered position.For this purpose, this invention provides a vehicle seat moving apparatus constructed as follows. Provided on a rotation base 31, for rotating a seat main body 10 between a position where it faces the front side of the vehicle and a position where it faces a door opening, is a widthwise slide base 41 that moves horizontally in the vehicle width direction while the seat main body 10 faces the door opening. The seat main body 10 is supported by the slide base 41 via four-bar linkage mechanisms 44. Guide rollers 46 are attached to upper link arms 44a of the four-bar linkage mechanisms 44. The guide rollers 46 are placed on cam surfaces of cam plates 47 provided to the rotation base 31. The cam surfaces have continuously extending inclined guide surfaces 47b that guide such that the guide rollers 46 move obliquely upwards when the widthwise slide base 41 moves.
