PROBLEM TO BE SOLVED: To provide a valve opening structure of a float valve capable of improving sealability by using a single seal structure, reducing the production of the float valve, and improving re-valve opening property after the valve is closed. SOLUTION: This valve opening structure comprises a case, a valve seat formed at the upper opening of the case, a float vertically movably installed in a space formed in the case, a valve holding member installed at the top of the float and formed in such a size that can be inserted into the opening, a valve formed on the valve holding member and allowed to abut on the valve seat, and a valve opening member vertically movable together with the float. When the valve is opened, the valve opening member opens the valve at one or more positions. COPYRIGHT: (C)2007,JPO&INPIT
