PROBLEM TO BE SOLVED: To provide a refrigerant circulating part connecting structure of a refrigerating cycle having improved pressure tightness. SOLUTION: This structure comprises a passage member 26 having a refrigerant passage 28 communicating to a refrigerant outlet header 22 via one end opening, a pipe 25 being connected to the passage member 26 with the tip part being engaged into the other end opening of the refrigerant passage of the passage member 26, a fixing member 27 for fixing the pipe 25 to the passage member 26, and a screw fastening means for fixing the passage member 26 and the fixing member 27 at one end part. An engaging part 32 is provided to the passage member 26 for preventing detachment of the passage member 26 and the fixing member 27 by engagement into a projecting part 35 of the fixing member 27. A refrigerant passage 28 is formed on the passage member 26 at the other end part as that of fixing side by the screw fastening means and the engaging part of the passage member 26 is engaged with the projecting part 35 of the fixing member 27 at an end on which the refrigerant passage 28 is formed.
