An air passage forming member includes an air passage inner wall surface that forms a wall surface of a connecting air passage connected to a cushion air passage. A blower device case has an air intake opening that is connected to the connecting air passage. A centrifugal fan is received in the inside of the blower device case. The air passage forming member is arranged such that at a downstream end of the connecting air passage, the air, which flows along the air passage inner wall surface in the connecting air passage, forms an air flow, which is directed in an axial direction of a fan central axis, or an air flow, which is directed toward an outer side in a radial direction of the fan central axis in comparison to the air flow that is directed in the axial direction.
