To enable the passage of the suction inlet air into an evaporator and a condenser to be equalized without incurring cost increase by mainly improving the form of an air-conditioning case.
Inside the air-conditioning case 38 having a suction inlet port 391 and a suction outlet port 392, an air passage 393 between the suction inlet port 391 and the suction outlet port 392 is formed between opposing sidewalls of the air-conditioning case 38. The evaporator 31 and the condenser 32 are arranged at a heat exchanging area 393a of the air passage 393 by partitioning the suction inlet side heat exchanging area facing one of the walls of the opposing sidewalls and the suction outlet side heat exchanging area facing the other wall. The suction inlet port 391 is provided upward near the side of one of the sidewalls of the ceiling wall of the air-conditioning case 38 and leads to the suction inlet side heat exchanging area from the upper part. The suction outlet port 392 is provided at the lower part of the end part wall 38a of the air-conditioning case 38 and connects to the suction outlet side heat exchanging area from the side. One of the sidewalls has an inclined face 25 which rises aslope on the side away from a suction face 395a near the lower end rim of the suction face 395a of the evaporator 31.
