Abstract

A seat air-conditioner includes an inlet portion, a blower, and a door device. The inlet portion is disposed inside a seat and defines a first inlet and a second inlet. The blower is disposed inside the seat. The door device is configured to be moved to open the first inlet while closing the second inlet and to close the first inlet while opening the second inlet. The first inlet is arranged such that an air drawn into the seat through a passenger supporting portion of the seat is drawn into the blower through the first inlet. The second inlet is arranged such that an air drawn into the seat through a portion of the seat other than the passenger supporting portion is more likely to be drawn into the second inlet than into the first inlet.
