Zusammenfassung:	PROBLEM TO BE SOLVED: To make it simple in structure less in the number of part items and small in size as well as to facilitate the work of mounting to a cistern. SOLUTION: A tubular valve body 4 forming a discharge port 3 of a cistern 2 is installed in this cistern 2 after piercing through a wall being close to the bottom. A valve stem 11 installed in this valve body 4 is supported by a bearing member 33 free of movements in the axial direction. In addition, a drive unit 38 of a shutoff valve 20 is attached to an outer boundary of the valve body 4, and its driving shaft 42 and the valve stem 11 are connected to each other by a lever 43. This drive unit 38 is usually connected to a commercial power source by a control circuit, and in time of power failure, it is made so as to be connected to an auxiliary power source. When the driving shaft 42 is rotated by drive of this drive unit 38, the valve stem 11 is rectilinearly shifted in the valve closing direction by the lever 43, making a valve element 6 adhere close to the discharge port 3.
