Claims

[Scope of Claim for Utility Model Registration] ■ Two types of synthetic resin bellows pipes 1 and 2 with different diameters are fitted together in a concentric or nearly concentric state, and the bellows pipes 1 and 2 are fitted as appropriate in the tube axis direction. An annular heat insulating space 3 which can be screwed together from one direction in the tube axis direction between the pipe parts located at intervals, and which is formed between both the bellows pipes 1 and 2 in the screwed state. The outer bellows pipe 1 is formed at a plurality of locations appropriately spaced in the axial direction of the inner bellows pipe 2 or the outer bellows pipe 1.
A member 4 that comes into contact with the inner circumferential surface of the inner bellows tube 2 or the outer circumferential surface of the inner bellows pipe 2 to regulate the interval in the diametrical direction of the heat insulating space 3 is attached to the threaded portion 1a. A train hose that is integrally molded so that it can pass through 2a. (1) The space regulating member 4 is configured to be in close contact with the inner surface of the minimum diameter portion of the outer bellows pipe 1 or the outer surface of the maximum inner diameter portion of the inner bellows pipe 2. - Lane horse. (1) Lane hose according to claim 1 or 2, wherein the distance regulating member 4 is a bar-shaped projection. (1) Lane hose according to claim 1 or 2, wherein the distance regulating member 4 is an annular projection. (2) The drain hose according to claim 1 or 2, wherein the distance regulating member 4 has a spiral projection.
