Claims

[Scope of utility model registration request]

a driven member rotatably supported by the driving member and whose interior is separated into a storage chamber and an operating chamber by a partition plate; and a driven member fixed to the driven member and facing into the operating chamber;
and a rotor that cooperates with the driven member to form a labyrinth groove; a return passage having an opening at one end formed in an inner end surface of the driven member to return the working fluid in the working chamber to the storage chamber; A flow path portion formed between a side end surface and an inner end surface of the driven member and guiding the working fluid in the working chamber to the return passage, and a protrusion near the front side hole edge of the return passage opening in the rotor rotation direction. A fluid coupling is provided with a protrusion that controls the pumping action of the working fluid guided from the flow path portion to the return passage, wherein a holding hole with one end opening toward the rotor is formed in the protrusion; In the holding hole, between the upper surface of the protrusion and the side end surface of the rotor,
A fluid coupling characterized in that an adjustment member is provided that can freely move forward and backward with respect to an intermediate portion.
