A refrigerant pipe connected to a suction side of a compressor and a refrigerant pipe connected to a discharge side of the compressor are integrated into one body. A refrigerant pipe connected to an inlet side of a condenser and a refrigerant pipe connected to an outlet side of the condenser are integrated into one body. A refrigerant pipe connected to an inlet side of a decompressor and a refrigerant pipe connected to an outlet side of the temperature detecting portion are integrated into one body. In these piping structures, a double pipe structure and a double pipe joint structure are adopted in which an inner pipe for circulating high pressure fluid and an outer pipe for circulating low pressure fluid are formed separate from each other and the respective end portions of the pipes are joined to a joint member by plastically deforming the pipes.

A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be radially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.

A method of manufacturing a double pipe includes a step of inserting a straight inner pipe into a straight outer pipe such that the inner pipe and the outer pipe are positioned at a predetermined relative position, a step of fixing a first end portion of the outer pipe to the inner pipe so as to form a first fixing portion, a step of bending the outer pipe and the inner pipe at the same time at a predetermined portion so as to form at least one bending portion after the fixing step of the first end portion, and a step of fixing a second end portion of the outer pipe to the inner pipe so as to form a second end portion after the bending.
