PROBLEM TO BE SOLVED: To provide a washing device for a toilet contributing to water saving while suppressing the quantity change of wash water supplied to a toilet bowl. SOLUTION: A weight 37 is fixed to a valve element 36. In the case of automatic washing by a forced cut-off system, washing time in large wash and small wash is adjusted by the stop time in the normal rotation stop position of a motor 51, that is, the motor 51 is stopped only for a predetermined small wash holding time in small wash, and the motor 51 is stopped only for a predetermined large wash holding time in large wash. Since the weight 37 is fixed to the valve element 36, the valve element 36 smoothly sinks without floating. The quantity of wash water supplied to the toilet bowl can thereby be precisely adjusted according to small wash and large wash. As a result, the quantity change of wash water supplied to the toilet bowl can be suppressed while contributing to water saving. COPYRIGHT: (C)2004,JPO&NCIPI
