PURPOSE:To make a washing device lightweight and compact by fitting at least one piece selected from among a plurality of spray nozzles to a rotary member so that the direction of spray is freely changed and controlled for the rotary member along the turning face thereof. CONSTITUTION:A rotary member 3 is freely rotatably fitted to a washing device main body 1m around the axial center Z of a pipe being a washing object. A plurality of spray nozzles 4 are provided to this rotary member 3 to spray washing water on the inner wall surface 6 of the pipe. At least one piece selected from among a plurality of spray nozzles 4 is fitted to the rotary member 3 so that the direction of spray is freely changed and controlled for the rotary member 3 along the turning face thereof. As a result, since the need for a driving mechanism for driving the rotary member is eliminated in the washing device main body side, the washing device is made lightweight and compact. |
