A washing device for parts of human body for use in a flush toilet which includes essentially a cylinder, a shaft and a water tank. The cylinder has a water supplying orifice and incorporates the shaft in the bore formed therein. The shaft comprises a shaft body and a control axis which is coaxially mounted in the bore of the shaft body. The shaft body has, at one end, a water spouting nozzle and an inflow orifice communicating a water passage to the water inlet port of the cylinder, and has, at the other end, a lever to rotate the whole shaft body. By operation of the lever, water spouting nozzle is movable to or from its inoperative rest position. An amount of washing water to be spouted is controlled by adjusting a sectional area of the water passage. This adjustment is effected by axial movement of the control axis which is provided with a tapered valve portion at one end and is provided with one operating knob at the other end thereof. The knob protrudes from one extremity of the shaft body.
