PROBLEM TO BE SOLVED: To reduce leakage positions of high-pressure refrigerant which may leak from a connection part of a high-pressure pipe to the outside in a refrigeration cycle of a motor vehicle air conditioner. SOLUTION: All of high-pressure pipe joints H1-H5 using sealing materials of high-pressure pipes 7, 11 and 12 which are located from a refrigerant outlet of a compressor 1 to a refrigerant inlet of an expansion valve 4 are disposed in low-pressure pipes 15, 16 and 17 located from a refrigerant outlet of an evaporator 5 to a refrigerant inlet of the compressor 1 to reduce the leakage positions of the high-pressure refrigerant, where the sealing parts by the sealing materials of the high-pressure pipe joints H1-H5 are directly exposed to atmosphere, to zero.
