First, the protective tube P is bent and inserted into the fitting groove 31 from the opening on the back side of the plumbing tool main body M ′, and then the pipe is inserted into each fitting flange 32 at both ends of the plumbing tool main body M ′. The closure lid 33 is fitted from the bending direction of the fitting main body M ', and the pipe fitting main body M'
At both ends in the curved direction, the protective tube P bent and fitted into the internal fitting groove 31 is prevented from coming off in the curved radial direction. In this state, the curved plumbing fixture A 'is fixed to the floor lower surface G via the pair of legs 34,
The protective pipe P is piped, and a hot water supply pipe (not shown) is pushed in from one end of the protective pipe P and is passed therethrough.

全く同様にして生ずる。However, when the hot water supply pipe is passed through the protection pipe P, the bent portion of the protection pipe P is displaced with respect to the bent pipe A 'due to the resistance of the pipe. As shown by the dotted line, the curved diameter of the protective tube P tends to be smaller. As a result, the pipe resistance of the hot water supply pipe is further increased, which sometimes makes it difficult or impossible. As described above, this problem occurs not only when a pipe is passed through a flexible pipe but also when a wire such as an electric wire is passed through another flexible pipe such as a bent conduit pipe. Also,
It happens in exactly the same way.

Then, the pipe body is fixed to the lower surface of the floor or the like, and the flexible pipe is bent. Thereafter, a pipe such as a hot water supply pipe or a wire such as an electric wire is inserted from one end of the flexible pipe to pass through the pipe. Even when the pipes or the wires reach the curved portion of the flexible tube supported by the curved pipe fitting, the curved portion of the flexible tube is reduced by the diameter preventing device. Since the outside is held so that the curved diameter does not become small, the flexible tube does not shift with respect to the plumbing tool main body, and the pipes and wires are formed in a curved shape of the flexible tube. In accordance with, it is fed smoothly while being bent, and it is passed and piped.

The protective tube P has both appropriate flexibility and rigidity, and is also referred to as a sheath tube. First, as shown in FIGS. 9 and 10, a closing ring R is loosely fitted from the upper end of the protective tube P to the outside thereof, and the upper end of the protective tube P is inserted into the pipe insertion portion 3 of the plumbing device main body M. Through
Both the closing ring R and the piping tool body M are loosely fitted to the protective tube P. Thereafter, as shown in FIG. 11, the curved portion of the protective tube P is fitted into the fitting groove 4 inside from the opening on the outer peripheral side of the plumbing tool main body M, and the wall surface W and the floor lower surface G are formed. The pipe fitting main body M is installed at the corner formed by the above, and the closing ring R loosely fitted to the protective tube P is moved toward the pipe fitting main body M in the middle thereof, as shown in FIG. The closing ring R is fitted to the outside of the ring fitted portion 6 so as to be closed. In addition, as shown in FIG. 11, when the plumbing tool main body M is installed at a predetermined position, the plumbing tool main body M is loosely fitted into the protective tube P via the pipe insertion portion 3 at the upper end thereof. Therefore, the work of installing the plumbing tool main body M at a target position becomes easy.

In the Curved pipe tool A 1 of the present embodiment, the one end portion of the fitting groove 4, have is provided tube insertion portion 3, the outer opening of the fitting groove 4 of the part, the tube insertion It is closed by the peripheral wall of the part 3. For this reason, by closing the closing ring R outside the ring fitting portion 6 of the plumbing tool main body M, the openings at both ends of the fitting groove 4 provided in the plumbing tool main body M are both closed. At both ends, the protective tube P fitted into the fitting groove 4 does not come off in the direction of the curved radius. In addition, in the portion of the closing ring R, the inner circumferential surface of the closing ring R is caused by the reaction force of the bent protective pipe P to escape in the radial direction of the bending, and the outer circumferential surface of the ring fitted portion 6 is formed. Therefore, the structure is such that the closing ring R does not easily come off the ring fitted portion 6. In addition, when the blocking ring R once fitted is removed for some reason, the protection tube P is pulled toward the ring fitted portion 6 to eliminate the reaction force acting on the protection tube P. Good.

Pipes and wires can be used to hold the center of the pipe in the bending direction from the outside and to prevent the flexible tube from coming out of the fitting groove and reducing its bending diameter. Even when a flexible tube is passed through a flexible tube, the bent portion of the flexible tube does not shift with respect to the plumbing body due to the resistance of the flexible tube and the wire, and the tube inserted into the flexible tube. The type and line can be smoothly fed into the curved portion while being curved, following the curved shape of the flexible tube. As a result, the work of pipes and wires for pipes and wires becomes easy.
