Abstract:
The present invention prevents a locking structure for fixing a rotatable valve body to an open position from protruding to the outside, and thus prevents the locking structure from being damaged. This female joint (10) comprises: a joint body (16); a valve member (18) that is rotatably disposed in the joint body (16); a locking element (22) for locking the valve member (18); and a sleeve (24) for holding the locking element (22) from the outside in a radial direction. In a coupled state, the locking element (22) holds, in a locked position, the valve member (18) engaged with a locking groove (36) formed on an outer surface (38) of the valve member (18). A rotary shaft part (44) of the valve member (18) and the locking element (22) are covered from the outside in the radial direction by the sleeve (24) and are not exposed to the outside.
