PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle which reduces noise caused by pressure fluctuation without reducing the blast volume of a blower.SOLUTION: In an air conditioner 10 for a vehicle, a blower 18 is housed in an air-conditioning case 14 and a suction port 34 opens so as to face a rotary fan 56. An inner/outer air switch unit 16 is connected with the suction port 34 through a connection passage 36. A resistance part 48 formed along an extension direction of the connection passage 36 and protruding to an inner peripheral surface is formed in the connection passage 36. The resistance part 48 is formed so that a cross sectional area gradually increases from the inner/outer air switch unit 16 side to the air-conditioning case 14 side. |
