To provide a fluid coupling that reduces the load on the main body of the fluid coupling so as to improve the durability. A fluid coupling (1) disposed in a pressure container (5) includes: a main body (2) having a through-passage (22) that is communicated with the pressure container (5) and allows flow of fluid; and a receiving member (6) disposed in the pressure container (5) to support this main body (2). The main body (2) has: an engaging portion (2o) that is formed on one side of the through-passage (22) and is disposed to be engaged inside the pressure container (5); and a conical surface (2j) formed on another side. The receiving member (6) has: a receiving portion (6b, 6c) having a tapered surface 6c with a groove angle identical to that of the conical surface (2j); and a circulation passage (6e, 6d) communicated with the other side of the through-passage (22). The conical surface (2j) of the main body (2) abuts on the tapered surface 6c of the receiving member (6) such that the receiving member (6) supports the main body (2).
