<p>A leg (50) is pivotably supported by a cushion frame (16) so that a part of the leg (50) is received in a space (S) surrounded by the cushion frame (16). Owing to the part of the leg (50) being received in the space (S) when the leg (50) is folded, when the seat cushion (12) is flipped up to a stowed position thereof located along a vehicle interior side wall (34), the part of the leg (50) is received in the space (S). As a result, the amount of projection of the leg (50) from the cushion frame (16) is reduced by an amount corresponding to the thickness of that portion of the leg (50) which is received in the space (S).</p>
