Provided is a float valve device that closes an opening portion by pushing a movable valve by means of a protruding portion formed on an upper portion of a float, in which a problem of a crack and the like of the movable valve can be solved without thickening the movable valve or increasing the movable valve in size. A space in a housing is defined into a lower space and an upper space through an intermediation of a partition wall, and an opening portion is provided in the partition wall. A float is housed in the lower space of the housing so as to be vertically slidable, and to an upper portion of the float, a movable valve is mounted so as to be movable relatively to the float in a vertical direction and a lateral direction. A protruding portion is provided on the upper portion of the float, and a receiving portion on which the protruding portion abuts is provided on a lower surface of the movable valve. A center hole is provided in a center of the receiving portion. When the float comes up, a peripheral portion of a top portion of the protruding portion of the float is adapted to abut on an inner circumference periphery of the center hole. |
