[0029]

The present invention relates to a hydraulic rotating device having a structure in which a water turbine is rotated by utilizing water pressure, and an output rotary shaft is rotated via a reduction gear in a speed reducer chamber at a lower portion of the water turbine chamber. The bottom of the chamber has a drainage hole for draining the residual water to the outside, in addition to the drainage channel for draining the water jetted to the water turbine, so that the water turbine chamber can be stopped when it is stopped and stored. Since the water accumulated in the water is satisfactorily discharged from the drain hole, the residual water in the water turbine chamber is almost eliminated, and it is possible to prevent the residual water from spoiling inside and causing slime or dirt.

Further, since the water drain hole is formed at a position rotated by 90 ° to 200 ° from the nozzle for jetting the jet water, the jet water jetted from the nozzle can be properly rotated by the water turbine to be drained. The jet water discharged from the passage and for rotating the water turbine rarely flows out through the water drain hole, and the water turbine can be efficiently rotated.

Since the drainage hole for draining the residual water to the outside is also formed on the bottom surface of the speed reducer chamber, the water accumulated in the speed reducer chamber is discharged to the outside, so that the inside of the speed reducer chamber is drained. This has the effect of preventing the generation of dirt due to the residual water rotting around the gear.

Further, since the water drainage hole of the water turbine room or the speed reducer chamber can be stored so as to be tilted so that the water drainage hole is located at the lowermost end, if the water drainage hole is hung on a hook or the like and stored, the internal water remains in the water drainage hole. Since water collects and the residual water inside is naturally drained to the outside, there is no need to purposely incline in order to drain the water, and there is an effect that the residual water inside can be drained satisfactorily.

Further, since the cleaning brush is provided at the tip of the output rotary shaft, the water wheel can be rotated by water pressure, and the brush attached to the rotary shaft can be rotated to clean the bathroom satisfactorily. Will be things.

Further, by providing a member at the tip of the output rotary shaft for converting the rotary motion into reciprocating motion or pressing motion,
By changing the rotational force due to water pressure to reciprocating motion or pressing motion, the shoulder, neck, etc. can be massaged, and the massage can be favorably performed in the bathroom.
