PROBLEM TO BE SOLVED: To provide a pipe joint enabling one-touch connection of pipes such as resin pipes to be promptly and easily performed, which can be precisely connected while securing sealing performance by correcting an insertion direction and the position of an axis core in the pipe, and which prevents breakage after pipe connection and improves force preventing pulling-out of the pipe while preventing a total size from being enlarged.SOLUTION: The pipe joint includes a seal member 16 in an outer periphery of an inner cylinder 11 provided in a joint body 2, and has a pipe insertion gap 21 between a resin-made outer cylinder 3, which is provided in the joint body 2 and can be seen through, and the inner cylinder 11. Then, a cap body 4 having a connection mouth 18 at an outer edge side is fixed in the outer cylinder 3 in a state where a pulling-prevention ring 5 is stored. In the pipe joint, a swelling thick section 24 is formed at a side near an outer edge shoulder section of the cap body 4, and the pipe joint has an earthenware-mortar-formed tapered face 26 toward the connection mouth 18 from the swelling thick section 24. |
