Claims

[Scope of utility model registration request]

A synthetic rubber cap is attached via a sealing filler to the end of the cut pipe where a closed part is formed by crushing it in the diametrical direction so that the inner surface is crimped over a predetermined length in the pipe length direction from the cut surface. The structure of the shutoff part of the piping.
