い角度に形成したことを特徴とする流体継手。 A socket having a plug insertion part that has a fluid passage hole and communicates with the fluid passage hole in a substantially concentric state, and a fitting part for the socket that has a fluid passage hole and is approximately concentric with the fluid passage hole. a plug having;
The socket and the plug are provided with a locking mechanism consisting of a sleeve, a locking ball, and an engagement groove of the locking ball for locking the socket and the plug when they are connected, and the socket and the plug are inserted into each other through the locking mechanism. In a fluid coupling in which the two can be freely connected and separated, a lock ball constituting a part of the lock mechanism provided in the socket is housed so as to always protrude from the outer circumferential surface of the socket main cylindrical part,
In addition, a cylindrical space concentric with the socket main cylinder part is formed on the inner circumferential surface of the plug-side open end of the sleeve of the same mechanism, and at the back of the space there is an angle α of 45 with respect to the central axis of the main cylinder part. A tapered surface is formed at an angle smaller than 45°, and a groove wall surface angle β near the plug tip of the lock ball engaging groove on the plug side is formed at an angle of 45° or larger with respect to the central axis of the plug main cylinder. A fluid coupling characterized by:
