PROBLEM TO BE SOLVED: To improve the maintenance property of an evaporator. SOLUTION: An air inlet opening 11 is formed in a case 10. A filter 20 is provided in the case 10. An evaporator is provided in the case 10 adjacent to the filter 20 at the air downstream side thereof. The air inlet opening 11 is formed such that the evaporator and the filter 20 can be taken outside from the case 10. Since the evaporator and the filter 20 can be easily taken outside from the case 10 via the same air inlet opening 11, the evaporator can be taken out from the case 10.
