The other end of the water supply pipe 5 is connected to the end of the internal water channel 7 of the local cleaning device 6 via a connection fitting 10. As shown in FIG. 4, the connection fitting 10 has a drain plug mounting hole 10a.
The external thread 13 of the drain plug 12 is detachably screwed to the internal thread 14 formed on the inner peripheral surface of the drain plug mounting hole 10a. A strainer 8 is provided at the tip of the connection fitting 10. When the drain plug 12 is attached, the strainer 8 is made to protrude into a water passage in the connection fitting 10 as shown in FIG. When the flowing water flows to the outlet side of the connection fitting 10, it flows through the strainer 8, and dust and the like are collected at the strainer 8. The local cleaning device 6 is attached to the toilet bowl 1, and although not shown, a solenoid valve, a pressure regulating valve, a heating unit, and the like are provided in an internal water channel 7 in the local cleaning device 6. A cleaning nozzle 6a connected to the end of the in-apparatus water channel 7 of the local cleaning device 6 is movable in the toilet bowl 1, and cleans a local part of the human body with hot water jetted from the cleaning nozzle 6a.
