SOLUTION: A width direction slide base 41 for horizontally moving the seat body 10 in a state of facing a door opening part in a vehicle width direction is provided on a rotary base 31 rotating the seat body 10 within a rotation range between a position facing a vehicle front and the position facing the door opening part, and the seat body 10 is supported by the slide base 41 through a four-bar link mechanism. A guide roller 46 is attached to an upper link arm 44a of the four-bar link mechanism 44, and the guide roller 46 is placed on a cam surface of a cam plate 47 provided to the rotary base 31. The cam surface has a continuously extended inclined guide face 47b for guiding the guide roller 46 to move in an oblique direction when the width direction slide base 41 is moved.
