。12 is fixedly attached to the tip of the nozzle 8, and guides the nozzle by contacting the inner circumferential wall of the tube 1 so that the nozzle turns along the inner circumferential wall 2a of the tube 1 when the nozzle 8 rotates due to its injection reaction force. This is an elongated nozzle guide member. As this elongated nozzle guide member 12, for example, a rubber tube, a vinyl tube, a metal wire, etc. may be used.
Considering the forward and backward movement of the bent portion of the tube, it is desirable that the material itself has elasticity. Moreover, the elongated nozzle guide member 12
is bent so that its tip 12a is offset from the center line of the shaft hole 11 of the nozzle 8, as shown in FIG. A metal sphere 13 is fixedly attached to the distal end portion 12a so that the elongated nozzle guide member 12 and the like can easily move forward following the bent portion of the tube.

ことはない。"Function" In the above configuration, when high-pressure cleaning water is supplied from a pump (not shown) to the cleaning hose 2, it passes through the introduction hole 4 from the insertion end 2a of the cleaning hose 2, and first passes through the nozzle support 3. Cleaning water flows inside. At this time, the nozzle 8 slightly slides toward the tip side due to the pressure of the fluid, but the cylindrical connecting portion 8a of the nozzle
A cylindrical blade fixing body 1 fixedly attached to the insertion end of the
0a contacts the plate 7 and does not come off from the nozzle support 3.
次にノズル支承体３内の洗浄水は軸孔１１を通り、各噴

リング５により一層高まる。At this time, the nozzle 8 rotates in its circumferential direction due to the jet reaction force. Therefore, this rotational force is further increased by the bearing 5 that supports the vane 10 and the nozzle 8 that receive the energy of the fluid trying to pass through the shaft hole 11.

The tip 12a or the sphere 13 of the nozzle 8 is always in contact with the inner circumferential wall 1a of the tube 1, whereby the nozzle 8 is guided and rotates along the inner circumferential wall 1a of the tube 1 as shown in FIG. Therefore, even if the pipe to be cleaned has a larger diameter than shown in FIG. 1, the nozzle 8 rotates without moving away from the inner peripheral wall of the pipe or without moving away significantly. Moreover, since the nozzle 8 rotates and the injection hole 9 is oriented obliquely toward the inner circumferential wall of the tube, the nozzle 8 moves forward by the propulsion force.
