The water discharged from the water film spout 62 flows toward the front end portion 3 a of the first cleaning nozzle 3 and flows downward through the peripheral surface of the first cleaning nozzle 3, and the surface of the first cleaning nozzle 3. A water film is formed at 39. In a state where the first cleaning nozzle 3 has advanced to the foremost end, the water discharged from the water film spout 62 is supplied to the upper side in the vicinity of the rear end portion 3b of the first cleaning nozzle 3.
Note that, as described above, the water flow that is discharged from the water film spout 62 and forms a water film around the cleaning spout 32 of the first cleaning nozzle 3 is the cleaning spout 32 of the first cleaning nozzle 3. Since the cleaning water discharged from the first cleaning nozzle 3 is set to be weaker than the water flow of the cleaning water discharged from the first cleaning nozzle 3, a water film is formed on the cleaning water discharged from the first cleaning nozzle 3. It is possible to prevent the water forming the water from being mixed.

  When the operation unit is operated and the control unit receives a bidet cleaning start signal, as shown in FIG. 9, the second cleaning nozzle 4 advances to the front side in the forward and backward direction of the cleaning nozzle. When the second cleaning nozzle 4 comes into contact with the protrusion 231 of the shutter 22 and further advances to the front side, the shutter 22 is pushed up and the shutter 22 opens the opening 21c. When the second cleaning nozzle 4 further moves forward and advances to the foremost end (the position indicated by the two-dot chain line in FIG. 9), hot water for local cleaning is discharged from the cleaning water discharge port 42 of the second cleaning nozzle 4, Cleaning is performed.

When a predetermined time elapses after the bidet cleaning starts, or when the control unit receives a signal to stop the bidet cleaning, water discharge from the cleaning water discharge port 42 of the second cleaning nozzle 4 ends.
When the bidet cleaning is completed, the second cleaning nozzle 4 moves backward in the forward and backward direction of the cleaning nozzle and is accommodated in the second cleaning nozzle insertion portion 512 of the support portion 5. As described above, since the shutter 22 is urged so as to close the opening 21c, the second cleaning nozzle 4 moves backward and opens the opening 21c in the shutter 22. When the external force stops working, the shutter 22 rotates in a direction to close the opening 21c and closes the opening 21c.
