PROBLEM TO BE SOLVED: To provide a flushing water supply device capable of preventing overflow of flushing water from a flushing water tank even when at least a part of a cover body is displaced and cannot close an opening due to any cause.;SOLUTION: A flushing water supply device, which is provided in a flushing water tank and supplies flushing water to a water storage part of the flushing water tank, includes: a flushing water flow channel; an on-off valve provided in mid-course of the flushing water flow channel; an opening communicating a part of the flushing water flow channel positioned at the upper-stream side of the on-off valve with the outside of the flushing water flow channel; a cover body for closing the opening; and a cover member for covering at least a ceiling part facing the opening of the cover body. The cover member holds a predetermined clearance between it and the ceiling part when the cover body is not displaced by a water pressure of flushing water entering the flushing water flow channel, and regulates the displacement of the cover body within a range of the predetermined clearance when at least a part of the cover body is displaced toward the cover member by a water pressure of flushing water entering the flushing water flow channel.;COPYRIGHT: (C)2014,JPO&INPIT
