A vehicle seat includes a seat back and a head rest. The seat back has an air blower that is capable of aspirating air, and a blower duct that is capable of introducing the aspirated air toward a blowhole formed in the seat back. The head rest has a head rest main body and a stay attached to the head rest main body. The stay is inserted into the seat back, so that the head rest main body is vertically movably attached to the seat back. The air blower is disposed on the seat back such that a rotation center thereof can be positioned above the level of a terminal end of the stay that is moved to a lowermost position.
