<P>PROBLEM TO BE SOLVED: To reduce influence to the member of a screwing part side caused by the stress in a rotation direction occurring at a screwing part when screwing a screwed member to the screwing part by rotating the screwed member. <P>SOLUTION: A liquid refrigerant pipe 11 part is connected to a liquid side connection pipe 16 and an expansion valve 24 or the like, and includes: a liquid side closing valve 25 screwable with the liquid side connection pipe 16; a connection part 113a connectable with the expansion valve 24 or the like; and a loop-shaped part 112 composed of a loop-shaped tubular member that is provided with the liquid side closing valve 25 at one end and is provided with the connection part 113a at the another end. The rotary axis p1 of an outer wall 251a of the liquid side closing valve 25, for rotating the liquid side connection pipe 16 when screwing the liquid side connection pipe 16 to the liquid side closing valve 25, and a center axis p2 of a loop shape formed by the loop-shaped part 112, are set roughly parallel to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
