くなる。By the way, the conventional water tap 01 and the apparatus to which the tap is attached have the following various problems. (1) Since the outer diameter of the flange portion 08 of the cylindrical metal fitting 02 is smaller than that of the branch port 012, if a detaching force acts on the water tap 01, an effect of preventing the rubber ring 04 from being removed more than the shearing force cannot be expected. This is the same as in the case where a coil spring is annularly embedded in the rubber ring 04 because the spring escapes toward the inner surface of the tube. (2) Since a circular hole is formed in the fluid pipe 013 as the branch port 012, the hole edge on the inner surface of the pipe is not a circle on a horizontal plane, but a circle formed on a curved surface. There is a difference in height with the peripheral part. Since the tapered portion 010 and the flange portion 08 of the cylindrical metal fitting 02 are circles on a horizontal plane, even if the rubber ring 04 is pressed against the branch port 012, the compressed state becomes nonuniform, and there is a concern about fluid sealing. In particular, there is a problem near the hole edge in the pipe axis direction. (3) Since the rubber ring 04 is sandwiched between the tightening nut 06, the tapered portion 010, and the flange portion 08 via the washer 05, the washer 05 and the outer surface of the tube are in contact with each other, so that it is difficult to bend against a lateral force. (4) When the ground fluctuates due to an earthquake or the like and a large lateral force is applied to the water faucet 01 and tilts, the non-uniformity of the compression ratio in (2) further increases, and the pressure input on one side cannot be maintained. Since the rubber ring 04 is sandwiched between the flange portion 08, the tapered portion 010, and the washer 05, the rubber ring 04 may be damaged if the stopper moves. (5) Chips come out when piercing tube 013. This chip is located at the top of the tube, and when the tightening nut 06 is tightened in this state, the chip is caught between the washer 05 and the tube 013. There is no problem with the sealing mechanism in this state, but if the chips that have been trapped move due to vibrations caused by an earthquake or other work, vibrations caused by a vehicle, etc., and fall off from the lower part of the washer 05, only the thickness of the chips The faucet 01 is lowered, the press-fit state of the rubber ring 04 is released, and the sealing effect is greatly reduced. (6) If a cleaning bullet is sent with pressurized water or the like to clean the inner surface of the pipe after attaching the water tap 01, the cleaning bullet may be caught on the flange portion 08 of the water tap 01. (7) Since the rubber ring 04 is sandwiched between the tightening nut 06, the tapered portion 010, and the flange portion 08, the body of the cylindrical metal fitting 02 always receives a tensile load. For this reason, there is also a relationship between the screws on the upper part of the body, and the thickness of the body must be increased. Tube 013
Since the inner diameter of the cylindrical fitting 02 is smaller than the diameter of the branch port 012, the efficiency with respect to the diameter of the perforated hole is reduced in consideration of the flow rate and the like.

を目的とする。Accordingly, the present invention solves the above-mentioned conventional problems and can improve the force of preventing the fluid pipe from being detached from the branch port. It is possible to eliminate the unevenness of the compression rate of the rubber ring, to make it soft and bend even when a lateral force is applied, to prevent the rubber ring from being damaged even if it bends, and to prevent the sealing function from deteriorating. Moreover, even if chips are left at the top of the pipe, it does not affect the sealing function.In addition, even if a cleaning bullet is inserted into the inner surface of the pipe, it will not be caught. It is an object of the present invention to provide a method and an apparatus for mounting a water faucet that can be made smaller.

き剥離等が発生しない。According to the first aspect of the present invention, since the water faucet is attached as described above, the following excellent effects are obtained. (1) When a pull-out force acts on the water faucet, the outer diameter of the enlarged-diameter portion at the lower end of the cylindrical metal fitting is larger than the diameter of the branch port, so the endurance force withstands until the enlarged-diameter portion is deformed or broken. (2) Since the rubber ring is pushed out and the cylindrical fitting is press-fitted, regardless of the height difference of the rim of the branch port, the outer rim of the rubber ring and the branch port, and the outer circumference of the rubber ring and the cylindrical fitting. The surface pressure is even, and there is no concern about the sealing mechanism. (3) Even if a large lateral force is applied to the water faucet and tilts, the lateral force can be easily absorbed by the elasticity of the inverted flange at the upper end flange of the rubber ring and the lower end of the rubber ring, It can be easily bent without damaging the rubber ring. (4) When the ductile pipe is pierced, the lower part of the rubber ring after the water faucet is pushed is open even if the lining layer has an unstable shape such as chipping or peeling at the rim of the lining layer. It fits in a position that matches the shape of the edge, and does not affect the compression state of the rubber ring in the water stop portion. (5) Even if chips generated when the fluid pipe is pierced remain at the top of the pipe above the branch port, the upper flange portion of the rubber ring is depressed,
Absorb swarf. Chips do not fall off due to vibrations caused by earthquakes, other works, or vibrations caused by vehicles. If it falls off, it does not affect the compression state of the rubber ring. (6) Even if a cleaning bullet for cleaning the inner surface of the pipe is inserted into the inner surface of the pipe after attaching the water faucet to the fluid pipe, the cleaning bullet may be caught by the enlarged diameter portion of the cylindrical metal fitting. There is no. (7) There is no need to excavate the outer periphery of the fluid pipe to a large extent, and the water can be reliably stopped. (8) Since it is slightly rotated while being repeatedly pressed up (pressed / released) on the forming surface of the hook member from the lower end surface of the cylindrical member of the water faucet while being repeatedly pulled up, a buckling portion is not generated, and the forming surface and the tube are formed. There is little friction on the lower end surface of the metal fitting, and seizure and the like of the enlarged diameter portion do not occur.
