ABSTRACT:
In a washing device for parts of human body including a first hollow piston with a nozzle at the front end thereof and a second hollow piston with a nozzle at the front end thereof; a drive means for said first and second pistons comprises a single drive motor, a rotatable member to be driven by said motor and a belt-like member one end of which is anchored to the first piston and the other end of which is anchored to the second piston; said belt-like member has a middle portion engaging the periphery of the rotatable member and a pressurized water supply means. As one aspect of the invention, the rotatable member rotates reversibly at a fixed position and transmits the driving force to the belt-like member so as to move selectively the first and second pistons and a retracted inoperative position. In this case, these first and second piston move in opposite directions each other. While as another aspect of the invention, said rotatable member not only rotates reversibly, but also slidable while rotating, being assisted by a guide shoe and a resilient member normally urging the rotatable member in the extreme position. The washing device of this invention can selectively move the nozzle carrying pistons between operative and inoperative positions very quickly by a simplified drive mechanism.
