Abstract
Provided is a valve restrained from unintentional close. The valve includes a valve element formed with a flow-path hole, a holding member having inlet and outlet ports and holding the valve element while permitting its rotational movement in first and second directions, and a rotational restriction section. The valve element has an open position for making communication between the ports through the flow-path hole and a close position for blocking between the ports. The rotational restriction section restricts the rotational movement so as to stop the rotational movement thereof in the first direction at the open position where a specific part of the outer peripheral surface of the valve element overlaps the inlet port and receives pressure of the liquid to allow the pressure to impart a rotational bias in the first direction to the valve element in the open position.
