Claims

[Scope of utility model registration request]

A base including a pipe joint and a cutter, the pipe joint having a threaded hole, a first connecting part provided at one end of the base and connected to the outer circumferential surface of a main pipe made of synthetic resin, and a side part of the base. The cutter has a base having a threaded portion on the outer circumferential surface, a cylindrical portion provided at one end of the base, and a second connecting portion provided at the tip of the cylindrical portion. With the main pipe and the branch pipe connected by a pipe joint,
In a piping device in which a cutter is screwed into a threaded hole of a pipe joint to form an opening in the main pipe with its blade, a ventilation hole is formed in the cutter and the opening is formed in the inner peripheral surface of the cylindrical portion. A piping device specially designed to form a locking part to hold the resulting cutting chips.
