Claims

[Scope of utility model registration request]

A joint body provided with a connector on the circumferential surface to which a double pipe can be freely connected, extending in the axial direction of the joint body,
An inner and outer dual first and second fluid passages communicating with one and the other of the two pipes of the double pipe connected to the connector are formed, and an inner cylinder and an outer cylinder are provided at one end in the axial direction of the joint body. an inner and outer double cylindrical female socket portion consisting of an inner and outer cylinder, and an inner cylinder and an outer cylinder at the other end in the axial direction of the joint body, each having a shape that can be fitted to the inner cylinder and the outer cylinder of the female socket part. and an inner and outer double pipe-shaped male socket part, and the inner cylinder of each socket part is connected to the first socket part.
The opening end of the fluid passage and the outer cylinder of each socket portion constitute the opening end of the second fluid passage, wherein the inner cylinder of the male socket and the inner periphery of the inner cylinder and the outer cylinder of the female socket are formed. A joint is formed by forming a step surface having a shape that matches the end surface of the outer cylinder and a step surface having a shape that matches the end surface of the inner cylinder and the outer cylinder of the female socket on the outer periphery of the inner cylinder and the outer cylinder of the male socket. A branch joint for a double pipe, characterized in that when a male socket part of another joint main body is fitted into a female socket part of the main body, the end surfaces of each cylinder of each socket part abut against these stepped surfaces. .
