To discharge a prescribed amount of water and automatically close a valve by providing a manual operation means for opening a self-closing valve by manual operation.

A toilet stool washing device JV is provided to laminate and integrate a self-closing valve 2, to which a primary side water feed pipe is connected, having a self-closing function and a distribution valve part 1 synchronized therewith and performing the distribution feed of washing water, and the upper end of the distribution valve part 1 is connected to an output port part 4 having each output. Rotation and drive start is performed by pulling a manual lever 591 connected to an output gear 590 for a manual operation valve connected to a rotary shaft 22 by a gear array until a case end face 593a and a shaft end face 597a collide with each other. A mechanical drive source such as a spiral spring is connected to the rotary shaft 22, which is rotated and driven to the closing direction of the self-closing valve 2, and the distribution operation of the distribution valve 1 is performed. Thus, if manual operation is performed firstly, the closing of the self-closing valve can be performed automatically.
