<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive pipe joint structure capable of preventing a joint block from levitating due to internal pressure, ensuring sufficient sealing even if the joint block is inclined, and reducing leakage. <P>SOLUTION: A sealing member 50 has a skirt part 51 extending in the axial direction and a flange part 52 extending in the radial direction. A protruding part 32 as a plug part and a diameter expanded part 41 as a socket part are provided in a male side block 10A and a female side block 20A, respectively, and the sealing member is provided between the plug part and the socket part which are mutually fitted in a recessed and projecting manner to seal in the axial direction and the radial direction. A positioning projecting part 70 and a positioning recessed part 24 are provided in the male side block and the female side block, respectively. When fitting both blocks mutually in a recessed and projecting manner, these positioning projecting and recessed parts are also fitted mutually in a recessed and projecting manner. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
