When an air conditioning ECU determines that it is immediately before idling stop, the air conditioning ECU implements a front seat air conditioning mode even if the air conditioning ECU determines that an occupant intensive air-conditioning mode can be implemented. Accordingly, the air conditioning ECU controls opening and closing mechanisms so as to blow a conditioned air from driver's seat side outlet ports, and also blow the conditioned air from a passenger's seat side foot outlet port. Hence, in cooling operation, since a temperature increase of air drawn into an inside air inlet port is limited when the idling stop is carried out, temperature increase of air blown into the vehicle interior from the outlet port can be restricted. In other words, a temperature change in the vehicle interior can be limited when a travel engine stops due to the idling stop.
