2. Description of the Related Art In a pipe of a building or the like, if it has been used for many years, an adhered substance is generated on the inner wall thereof, and therefore it is necessary to remove the adhered substance and wash and remove it. As a device for cleaning the inside of this pipe, a pipe cleaning nozzle has been proposed in which high-pressure water is jetted from the nozzle and the nozzle is rotated (for example, Japanese Patent Laid-Open No. 58-91245).

However, such a pipe cleaning nozzle is
It is rotatably attached to the end of the hose and rotates (rotates) on the spot around this hose. Therefore, when cleaning the inside of a pipe having a relatively large diameter, the nozzle cannot be swung along the inner wall of the pipe, and therefore the cleaning ability of the nozzle itself for peeling and removing the deposits is poor. In addition, there is a problem that a special device is required to insert the pipe cleaning nozzle into the pipe.

Due to such technical problems, an injection hole for injecting high-pressure water is provided rearward, and the cleaning nozzle is advanced in the pipe by the reaction force of the high-pressure water ejected from this injection hole, and the cleaning nozzle is not supported. A pipe cleaning nozzle has been proposed in which an injection hole for generating a balancing force and a guide member are provided, and the cleaning nozzle is swirled (revolved) along the inner wall of the pipe by the high-pressure water ejected from the injection hole and the guide member. (For example, JP-A-2-207879).

However, the above-described pipe cleaning nozzle which is swung (revolved) along the inner wall of the pipe is not only complicated in structure but also has a slender guide member for performing the swiveling operation. Since the guide member is required to be formed into a shape, it is weak in strength. Further, since the guide member is provided so as to project from the main body portion, there is a drawback that the guide member is caught by a bent portion or a protrusion of the pipe and is broken. In particular, when the inside of the pipe is washed and retracted, it is often caught, and in some cases, the pipe cleaning nozzle is damaged, which is a practical problem. Further, since the structure is complicated, there is a drawback that the manufacturing cost becomes high.

[0016] The reaction force P 1 is the force P 2 for advancing the cleaning nozzle 5, is resolved into a force P 3 is moved in the radial direction. Therefore, as shown in FIG. 3, the cleaning nozzle 5 is pressed against the inner wall of the pipe 16 having a relatively large diameter by the action of the force P 3 that moves in the radial direction. When the end portion 3b of the nozzle comes into contact with the inner wall of the pipe 16, the tip portion 3b is tapered so that it loses balance and rotates in either the left or right direction, as shown by the dotted line. Displace along the inner wall.

In this state, the high-pressure water PW is jetted obliquely rearward from the jet hole 14 as a jet S to swivel the cleaning nozzle 5 in the direction of arrow a along the inner wall of the pipe 16.
The deposits on the inner wall can be peeled off and washed. FIG. 4 shows a cross section of a nozzle body 3 according to another embodiment. The injection hole 14a provided in the nozzle body 3 is formed so as to have an angle α with respect to the center line c of the nozzle body 3. It is set up. Therefore, when the jet S of high-pressure water PW is jetted from the jet holes 14a, the force P 3 that pushes the nozzle body 3 in the radial direction advances P 4 and the force P 5 that pushes the nozzle body 3 against the inner wall surface of the pipe. Therefore, there is an effect that the cleaning nozzle 5 can be rotated well.
