For this reason, even if dirt is attached to the upper portion of the outer surface of the nozzle during local cleaning, the dirt can be easily slipped off. The control device 60 determines that the nozzle cleaning end timing has come in S130 when the predetermined nozzle cleaning time before the local cleaning has elapsed since the start of the nozzle cleaning in S120.

  When it is determined that the end timing of the nozzle cleaning has come in S130, the control device 60 ends the nozzle cleaning and advances the cleaning nozzle (one of the posterior cleaning nozzle 21 and the bidet cleaning nozzle 22) to perform local cleaning from the nozzle cover 40 (S140), the flow path switching valve 29 is switched, the washing water outputted from the flow rate adjusting valve 27 is discharged from the washing nozzle for performing local washing, local washing is started (S150), and the process returns to S100. If any of the tail washing nozzle 21 and the bidet washing nozzle 22 has advanced from the nozzle cover 40, the control device 60 determines that the storage state is not in S100, and stop of the local washing (butt washing or bidet washing) It waits for an instruction (S160). The determination of S160 is performed based on whether the stop switch of the operation panel 14 has been operated. When it is determined that the stop of the local cleaning is instructed, the control device 60 ends the local cleaning (S170), switches the flow path switching valve 29, and discharges the cleaning water output from the flow control valve 27 into the forward cleaning device 50. By discharging from the outlet 51, the nozzle cleaning for cleaning the outer surface of the posterior cleaning nozzle 21 or the bidet cleaning nozzle 22 in the cleaning position is started (S180). Thereby, immediately after the end of the local cleaning, the cleaning water discharged from the front cleaning device 50 can be transmitted to the outer surface of the posterior cleaning nozzle 21 or the bidet cleaning nozzle 22 in the cleaning position to clean the outer surface. In this way, when the nozzle cleaning is performed, the control device 60 ends the nozzle cleaning when the nozzle cleaning end timing comes (S190), and the posterior cleaning nozzle 21 or bidet cleaning nozzle 22 in the cleaning position is within the nozzle cover 40. It accommodates in (accommodating position) (S200), and ends nozzle unit operation processing. The control device 60 determines that the nozzle cleaning end timing has come in S190 when the predetermined nozzle cleaning time after the local cleaning has elapsed since the start of the nozzle cleaning in S180.
