PROBLEM TO BE SOLVED: To provide a pipe joint structure having strength competing with non-average force due to inside hydraulic pressure without requiring large labor and time. SOLUTION: In the pipe joint structure, a plug 1 is inserted into a socket 2, a rubber ring 12 is interposed in an annular space between the inner peripheral surface of the socket 2 and the outer peripheral surface of the plug 1, a push ring 11 is attached to the outer periphery of the plug 1, and the rubber ring 12 is pushed and fixed with the push ring 11 into the annular space. A pin hole 21 is formed in the push ring 11, the pin hole 21 has an opening 22 facing the inner peripheral surface of the push ring 11. A lock pin 23 is inserted into the pin hole 21, so that the peripheral surface of the lock pin 23 pushes the outer peripheral surface of the plug 1 through the opening 22. The plug 1 can be prevented from coming out of the socket 2 by the pushing pressure. Because the joint can be prevented from coming out competing against the non-average force by inserting the lock pin 23, the configuration can contribute to the reduction of labor and time so as to achieve the pipe joint structure.
