The present invention provides a fluid coupling which can surely prevent liquid leakage, and reduce manufacturing cost and time. It includes a socket (11) which is provided with a socket main body (12), a fixed valve (21), a guide (30) which is engaged with the fixed valve (21) and is biased so as to be pressed against an inner surface of the socket main body (12), and a spring (4) which biases the guide (30), and a plug (51) which is provided with a plug main body (52), a movable valve (61), a spring (68), and a valve holder (71) which supports the movable valve (61) and the spring (62). When the plug (51) is inserted into the socket (11), the guide (30) moves rearward against a biasing force of the spring (49) so as to connect a flow path between the plug (51) and the socket (11). A fitted portion (35), which is fitted into the distal end of the plug (51), is disposed at the end portion of the guide (30). First seal members (41 and 42) are disposed between the fitted portion (35) and a distal end (55) of the plug (51).
