As shown in FIG. 5, a link mechanism used for switching to each of the outlets is provided, and in general, a cover for covering the link mechanism is attached in order to prevent damage by the foot of the occupant. A heat duct is connected to one of the plurality of outlets, and the outlet side of the heat duct is branched to extend to both sides in the vehicle width direction. The air outlet side extends over the engine deck to the driver's seat side and is located below the front portion of the driver's seat, while the other air outlet side passes over the cover and is below the side portion of the cover. It extends toward the front and is located below the front of the passenger seat. As a result, warm air is blown to the feet of the occupants in the driver's seat and the passenger seat. However, in the above air conditioner, the other air outlet side extends below the side of the cover, so the air conditioner (heater unit) must be relatively long in the vehicle width direction in the vehicle interior. I don't get it. For this reason, in general, in order to return the air inside the vehicle (inside air) to the blower inside the engine room, an inside air outlet is formed on the side of the heater unit (cover) on the dash panel, and the inside air outlet is formed. And the inflow port of the blower are connected, but in such a case, the inside air intake port faces the other outlet side of the heat duct, and the suction capacity of the blower decreases. I have no choice but to do it.
