PROBLEM TO BE SOLVED: To provide a pipe joint structure which has both of holding force in a pipe by biting of a claw part of a holding body, and a pipe movement stopping force of another holding body by mainly shortening the diameter, in which the holding force is superior compared to a conventional type. SOLUTION: The joint has a sealing material displaying a sealing function by being pressure welded to the outer surface of the pipe to be inserted, and a pipe holding material displaying a holding function by biting into the outer surface of the pipe which are incorporated in a joint base body, and the pipe is prevented from falling out by a cap. In the pipe joint structure, the pipe holding material is both a holding body A having a metallic claw part protruding toward the outer surface of the pipe, and a resin annular holding body B whose diameter can be shortened toward the outer surface of the pipe. The metallic holding body is denoted as A, the resin holding body B, the sealing material (O-ring) C, the cap D, the joint T, the joint base body TO, a slit 11, a claw part a of the holding body A, and a claw part b of the holding body B.
