PROBLEM TO BE SOLVED: To provide a pipe joint capable of bending at a joint part while enough keeping the strength of the joint part. SOLUTION: A flexible pipe 20 connecting pipes A, B is constituted by a cylindrical rubber cover 21 and an elastic coil 22 mounted in the inner peripheral surface of the rubber cover 21. The section of the coil 22 is formed substantially like a triangle having a base 22a along the inner surface of the rubber cover 21 and an apex part 22b opposite to the base 22a. The lines along the apex part 22b at both end parts of the elastic coil 22 have a function of a female screw engaged with the outer peripheral part of each of the pipes A, B connected to each other.
