ABSTRACT:
At least one coupling member (2) has a slide valve holder (42) that is pushed in by the other coupling member (3) when coupled to the coupling member (2). The coupling member (2) further has a rotary valve (41) rotatably supported by the slide valve holder. The slide valve holder has a through-hole (425) constituting a flow path. A valve seat (26) is provided around the through-hole. The rotary valve (41) has an outer peripheral surface portion that slidingly engages the valve seat. One end of a fluid passage (411) extending through the rotary valve is open on the outer peripheral surface portion. The rotary valve is displaceable toward the valve seat and is urged toward the valve seat by a spring member (64). Thus, the outer peripheral surface portion is pressed against the valve seat. When a fluid pressure acts in the coupling member (2) when the coupling members (2, 3) are not coupled to each other, the fluid pressure presses the rotary valve toward the valve seat.
