A cleaning valve drive unit constituted to be able to supply water to a toilet by manual rotational operation of a main shaft in which the main shaft is constituted to be able to pull out from a cleaning operation position to a draining operation position. Whereas an operation limiting mechanism with respect to the main shaft enables to carry out cleaning operation to the toilet by rotational operation around an axis line with respect to the main shaft when the main shaft is disposed at the cleaning operation position, when the main shaft is moved to the draining operation position, the operation limiting mechanism permits to drain water by the rotational operation around the axis line with respect to the main shaft.
