Patent ID: 6851448

Claim:
A rotary connector with valve, comprising a first and a second connector member each having a fitting portion and a connector portion provided with an inner bore serving as a liquid flow path, and a valve member arranged in the liquid flow path, wherein the first and the second connector member are coupled rotatably to one another by fitting the fitting portions together, wherein the valve member is seated in a valve-seating portion formed in the fitting portion; wherein the fitting portions of the first and the second connector members are provided with respective valve-pressing portions facing the valve-seating portion, wherein, by clamping and pressing at least a portion of the valve member between the two valve-pressing portions, liquid-tightness is preserved between the inner bore and the outside of the connector at a location at which the two fitting portions are coupled; and wherein a pressing force with which the two valve-pressing portions act on the valve member is set such that a frictional force exerted between the two valve-pressing portions and the valve member is in a range that allows the first connector member and the second connector member to rotate relatively to one another.
