Claims

[Scope of claim for utility model registration] By fitting the hose to the outside of the pipe,
A joint structure formed near the end face of a pipe for connecting the two, wherein a member that increases in volume upon contact with the liquid flowing in the pipe is disposed at a portion where the pipe contacts the hose. The joint structure is characterized by:
