ABSTRACT:
An apparatus for washing an endoscope by spraying washing liquid thereagainst is disclosed, which comprises a housing including a washing tank, and a rotary body rotatably mounted on a central portion of the washing tank. The rotary body has a horizontal cylindrical inner space formed in its upper portion. The rotary body carries an upper nozzle, which includes a cylindrical body capable of being retracted into the cylindrical space and a nozzle tip provided on the free end of the cylindrical member and directed downwards. The cylindrical member has a piston provided on its rear end and biased by a spring in the direction of retraction of the cylindrical member into the cylindrical space. The rotary body also carries a lower nozzle secured to its lower portion and directed upwards. When pressurized washing liquid is supplied to the upper and lower nozzles, it is sprayed from these nozzles against an endoscope which is set at a level between these nozzles. A this time, the cylindrical member is extended out of the rotary body against the biasing force of the spring by the pressure of the washing liquid.
