To provide toilet bowl electric equipment that can sufficiently operate even equipment of large power consumption.

A drying device 91, a heating device 92, a deodorizing device 93, and the like are operated by the output power of a storage battery 54 charged with the generated power of a hydraulic power generator 52 provided at a feed water pipe 51 for a low tank. When a voltage monitoring circuit 84 detects the output power of the storage battery 54 to be lower than the specified voltage, a switching element 82 is turned on to charge the storage battery 54 with power from a commercial power source 80, or a changeover switch is switched to operate the drying device 91, heating device 92, deodorizing device 93, and the like by the commercial power source 80.
