ABSTRACT:
A pipe joint unit includes a first pipe member with a male joint, a second pipe member with a female joint, and a pipe joint member coupling the first pipe member and the second pipe member. The male joint is received in the female joint such that an outer peripheral surface of the male joint is opposed to an inner peripheral surface of the female joint. The pipe joint member includes an engagement part that is elastically displaceable in the radial direction, and engages with the first and second pipe members. The male joint and the female joint have rotation restricting parts on the outer peripheral surface and the inner peripheral surface, respectively, for restricting relative rotation of the first and second pipe members.
