In this case, since the mounting portion 14 is pressed against the locking surfaces 8 by the elasticity of the sealing member 15, the communication joint 12 mounted on the mounting groove 7 does not rotate unnecessarily. Next, when the fluid flow path 9 of the next pipe member 2 is fitted into the insertion portion 16 of the communication joint 12, the pipe members 2 are connected in directions orthogonal to each other, and the fluid flow paths 9,. It is communicated by the passage 13 of the communication joint 12 and is sealed by the seal member 17.
