In a swinging apparatus (rotatively moving and swinging apparatus), a swing arm 51 positions a rotatively moving pedestal 45 and a cushion base 51 . The swing arm 51 is swung around a driving shaft 60 to swing the cushion base 51 , that is, to elevate or lower the cushion base 51 and to move it forward or backward. The cushion base 51 supports a seat portion 30 . When the seat is in a forward position in which it is directed toward the front of the vehicle, the swing arm 55 diagonally connects the members 51 and 45 together (Z type). This prevents, in the forward position, the swing arm 55 from extending upward from the cushion base 51 or the rotatively moving pedestal 45 from extending laterally from the seat portion 30 . Therefore, the size of the apparatus can be reduced across the width and height.
