<p><P>PROBLEM TO BE SOLVED: To provide a holder for pipe washing nozzle which is simple in structure, is hardly broken, is easily and inexpensively manufactured, prevents unwashed areas in a pipe by using an existing pipe washing nozzle, and also allowing washed deposits to surely flow downstream side. <P>SOLUTION: The holder 30 for pipe washing nozzle holds, at a prescribed height in piping, a pipe washing nozzle 20 that washes inside a pipe while self-travelling forward, by means of a reaction force when the holder is connected to the tip end of a washing hose 10, with water supplied by the washing hose 10 jetted rearward. The holder includes: a spherical frame body 31 that is roughly made spherical by combining a plurality of circular framesα<SB>1</SB>,α<SB>2</SB>,β<SB>1</SB>,β<SB>2</SB>; and a nozzle holding part 32 that holds the pipe washing nozzle 20 near the center of the spherical frame body 31 in a manner making the nozzle 20 rotatable around the shaft. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
