PIPE TAKING OUT STRUCTURE OF AIR-CONDITIONING UNIT FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a pipe taking out structure of an air-conditioning unit for a vehicle capable of preventing leak of air from a recessed part 50a while suppressing cost in the pipe taking out structure having the recessed part 50a on a contour of a connection block 50. SOLUTION: The pipe taking out structure of the air-conditioning unit for the vehicle is provided with an inner packing P4 arranged on the pipes 3a, 3b so as to close an inner side of an air flow passage of the recessed part 50a such as a pipe insertion groove; and an inner seal rib 1b for compressing/sealing the inner packing P4 to a case member 1. According to this, the inner packing P4 for sealing leak of air from the recessed part 50a is not a specific shape meeting a clearance shape and can be made into a packing of a strip-like simple shape. Thereby, the pipe taking out structure of the air-conditioning unit for the vehicle capable of preventing leak of air from the recessed part 50a while suppressing cost can be obtained.
