Claims

[Scope of utility model registration request]

(1) A pipe main body made of a metal pipe continuous in the longitudinal direction, and a small part of the pipe main body (both of which are integrally provided at the end on the side connected to the inner diameter pipe) and the above ice storage body. A small-diameter pipe connected to a large-diameter pipe, characterized in that the terminal joint part has a larger outer diameter.

(2) The above-mentioned pipe main body is formed of a single metal pipe with a length and a bending portion that match a predetermined piping shape. A small diameter pipe connected to the large diameter pipe described in (1).
