An air-conditioning case (2d) of a front air-conditioning unit (2) includes therein a branching duct (2c) for dividing the flow of the air-conditioned air to the seat (3) of occupants, and a cool/warm air switch (10) for switching the cool air (7) and the warm air (8) of the air-conditioned air and sending the resultant air to air supply ports (19). The air supply ports (19) are connected to the seat (3) by a single air duct (4). Therefore, the duct configuration is very simple. Also, the air duct (4) can be an existing one connected to the rear foot vent (30).
