Claims

[Scope of utility model registration request]

A stop valve for branch pipes that is attached to the end of a branch pipe that branches from a main pipe and communicates with the main pipe, and is inserted into the end of the branch pipe where water should be stopped, and is expanded by pressurizing fluid. a ring-shaped water-stop tube, a substantially drum-shaped support portion that holds the inner circumferential surface of the tube, and a retaining portion that is disposed at the bottom of the support portion and comes into contact with the inner circumferential surface of the main pipe. A stop valve for branch pipes, which is equipped with a stop part.
