Abstract
Provided is a float valve device which allows a valve to be quickly opened when, in a state in which a float has been raised as a result of a rise in fuel liquid level to close the valve, the fuel liquid level is lowered again. The float valve device includes a housing, a float accommodated in the housing, a movable valve adapted to abut a valve seat to close an opening, and a retention frame to retain the movable valve so as to allow the movable valve to ascend/descend by a predetermined distance and to incline with respect to the float. Further, a circumferentially uneven protrusion is formed on a portion where the retention frame and the movable valve abut each other. When the float is lowered in a valve-closed state, the protrusion first abuts the movable valve to impart a lowering force thereto.
