Abstract
A pipe may have enlarged and reduced diameters, which has low costs and which can prevent leakage of a fluid such as a refrigerant from the pipe even in such a configuration that a reduced diameter portion is continuous to an enlarged diameter portion continuous to another reduced diameter portion, the pipe being integrally and continuously formed by plastic or malleable working so as to having outer diameters (D1 . . . D8) which are longitudinally different from one another, and accordingly, the reduced diameter portion (1b-1c) being continuous to the enlarged diameter portion (1c-1d) which is continuous to another reduced diameter portion (1d-1e).
