FLUID COUPLING

PROBLEM TO BE SOLVED: To provide a fluid coupling capable of being quickly attached to a mounting subject. SOLUTION: The fluid coupling, which is removably connected to a screw connection n of a fluid passage port Re of the mounting subject E, is provided with a cylindrical main body 1 in which a fluid passage R1 is formed, a reciprocating member 2 which is externally fitted in the main body 1 to be freely movable in the radial direction of the main body, elastically urged to the projection side, and retreated by the contract with the mounting subject E, an interengaging member 3 which is engaged to and removed from the screw connection n by moving in the axial direction of the fluid passage R1, and engaged to integrally move with the reciprocating member 2, a cam operating portion K for operating the interengaging member 3 to the engaging side by retreating for the reciprocating member 2, a locking means H locked to the retreating position by automatic engagement as the reciprocating member 2 moves to the retreating side, and a seal body 4 sealed by the contact with the mounting subject E.
