Yes. That is, each insertion portion 33 has a diameter larger than the two types of tube diameters so that a plurality of types (two types in this embodiment) of resin pipes (water pipe 17 and drain pipe 18) can be inserted. Is set. For this reason, when the water pipe 17 is inserted through the insertion part 33, a gap is hardly formed between the inner peripheral surface of the insertion part 33 and the outer peripheral surface of the water pipe 17. On the other hand, when the drain pipe 18 is inserted through the insertion part 33, a large gap K is formed between the inner peripheral surface of the insertion part 33 and the outer peripheral surface of the drain pipe 18.

  Further, the peripheral wall of each insertion portion 33 is formed so that the thickness on the base end side (extension portion 32 side) is thicker than the thickness on the distal end side. That is, a thick portion 33 a that protrudes inward of the insertion portion 33 is formed on the inner peripheral surface of the insertion portion 33 on the proximal end side. Moreover, the peripheral wall of each insertion part 33 is formed so that it may become thin as it goes to a front-end | tip from the base end (thick part 33a). For this reason, the diameter (inner diameter) of each insertion portion 33 is formed so as to increase in diameter from the proximal end toward the distal end. For this reason, the gap K when the drain pipe 18 is inserted through the insertion portion 33 is narrow on the proximal end side of the insertion portion 33 and becomes wider toward the distal end side.

As shown in FIG. 5, the tube holding sleeve 36 is formed in a cylindrical shape. In addition, the tube holding sleeve 36 is formed in a cylindrical shape that is press-fitted into the gap K, and extends radially outward from the end of the cylindrical portion 37 to the cylindrical portion 37. And an engaging portion 38.

  A water stop portion 37 a that is thicker than other portions of the cylindrical body portion 37 and protrudes inward of the cylindrical body portion 37 is formed at the tip of the cylindrical body portion 37. For this reason, the inner diameter of the tube holding sleeve 36 is the smallest at the position corresponding to the water stop portion 37 a in the cylindrical body portion 37. The inner diameter of the tube holding sleeve 36 is set to be the same except for the water stop portion 37a.

  For this reason, it is the thickness of the wall part along the radial direction of the cylindrical part 37, Comprising: The thickness of the site | part corresponding to the water stop part 37a becomes thicker than the site | part corresponding to the thick part 33a in the said clearance gap K. Yes. On the other hand, it is the thickness of the wall part along the radial direction of the cylindrical part 37, Comprising: The thickness of parts other than the water stop part 37a is thinner than parts other than the thick part 33a in the said clearance gap K. Further, the locking portion 38 is locked to the open end (tip) of the insertion portion 33 when the cylindrical portion 37 is press-fitted into the insertion portion 33.

  Next, installation of the water pipe 17 and the drain pipe 18 to the unit bath wall 15 using the installation tool 10 so that the water pipe 17 and the drain pipe 18 pass through the through hole 19 drilled in the unit bath wall 15. A method will be described.

  First, as shown in FIG. 6, the end portion of the sheath tube 40 is connected to the sheath tube connection portion 21 in the installation tool main body 20 on the rear surface 15 a side of the unit bath wall 15. Next, the installation tool main body 20 to which the sheath tube 40 is connected is attached to the rear surface 15 a of the unit bath wall 15. In this attachment, the fitting tube portion 24 of the installation tool main body 20 is inserted into the through hole 19 from the rear surface 15a side of the unit bus wall 15, and the flange portion 23 is brought into contact with the rear surface 15a.

  Then, the mounting screw 42 is inserted into the screw hole 26 of the flange 23 and screwed into the unit bus wall 15. Then, the installation tool main body 20 is fixed to the rear surface 15 a of the unit bus wall 15, and the opening 22 of the installation tool main body 20 opens to the front surface 15 b side of the unit bus wall 15 through the through hole 19.

  Thereafter, the two water pipes 17 and the one drain pipe 18 are inserted through the sheath pipe 40, respectively. Then, the two water pipes 17 and the one drain pipe 18 are inserted into the installation tool main body 20 when coming out from the end of the sheath pipe 40. Further, when the two water pipes 17 and one drain pipe 18 are taken out of the installation tool body 20 from the opening 22 of the installation tool body 20, the installation tool body 20 guides the through hole 19. Is done.

  Next, the water pipe 17 and the drain pipe 18 drawn into the installation tool main body 20 are pulled out from the opening 22 of the installation tool main body 20 to the front surface 15 b side of the unit bath wall 15. Thereafter, the distal end portions of the water conduit 17 and the drain tube 18 are inserted into the insertion portion 33 of the cover member 30 on the front surface 15 b side of the unit bath wall 15.

  At this time, the diameters of the three insertion portions 33 are set to be the same, and the diameters are set larger than the diameters of the water pipe 17 and the drain pipe 18. For this reason, even if the water pipe 17 and the drain pipe 18 having different pipe diameters are drawn from any position of the opening 22, the water pipe 17 and the drain pipe 18 can be inserted into any of the insertion portions 33. It becomes possible.

  Further, the water pipe 17 and the drain pipe 18 are inserted into the insertion portion 33, the fitting piece 35 of the cover member 30 is fitted into the fitting cylinder portion 24, and the insertion hole 34 of the cover body 31 is installed. The screw hole 25 of the tool body 20 is matched. Thereafter, the screw 43 is inserted from the insertion hole 34 into the screw hole 25 and screwed, and the cover member 30 is assembled to the installation tool main body 20.

  Here, almost no gap is formed between the outer peripheral surface of the water pipe 17 and the inner peripheral surface of the insertion part 33 through which the water pipe 17 is inserted, and each water pipe 17 is held in the insertion part 33. ing. On the other hand, as shown by a two-dot chain line in FIG. 6, a gap is formed between the outer peripheral surface of the drain pipe 18 and the inner peripheral surface of the insertion portion 33 through which the drain pipe 18 is inserted. It is not held in the insertion part 33.

  Then, the tube holding sleeve 36 is attached to the drain pipe 18 from the cylindrical portion 37 side, and the tube holding sleeve 36 is moved along the drain pipe 18 toward the insertion portion 33. Thereafter, the cylindrical portion 37 is press-fitted into the gap between the outer peripheral surface of the drain pipe 18 and the inner peripheral surface of the insertion portion 33. At this time, the cylindrical portion 37 is press-fitted into the gap until the locking portion 38 is locked to the opening end of the insertion portion 33.

  Then, as shown in FIG. 1, the tube holding sleeve 36 is press-fitted into the insertion portion 33 so that the thick portion 33 a of the proximal end portion of the insertion portion 33 and the water stop portion 37 a of the cylindrical portion 37 face each other. The At this time, the water stop portion 37 a of the cylindrical body portion 37 is pressed toward the outer peripheral surface of the drain pipe 18 by the thick portion 33 a of the insertion portion 33, and the water stop portion 37 a is pressed against the outer peripheral surface of the drain pipe 18. Therefore, water is stopped between the outer peripheral surface of the drain pipe 18 and the inner peripheral surface of the cylindrical body portion 37, and water is stopped between the outer peripheral surface of the cylindrical body portion 37 and the inner peripheral surface of the insertion portion 33. The In addition, the water stop portion 37 a is pressed against the outer peripheral surface of the drain pipe 18, thereby suppressing the drain pipe 18 from moving along the axial direction in the insertion portion 33.

  As a result, no gap is formed between the outer peripheral surface of the drain tube 18 and the inner peripheral surface of the insertion portion 33, and the drain tube 18 is held in the insertion portion 33 by the tube holding sleeve 36. In this holding state, the pipe holding sleeve 36 interposed between the drain pipe 18 and the insertion part 33 prevents the drain pipe 18 from moving in the radial direction in the insertion part 33. Finally, the water pipe 17 led to the inside of the unit bath wall 15 through the installation tool main body 20 and the cover member 30, that is, through the installation tool 10, is connected to the faucet apparatus provided around the bathtub. Then, the drain pipe 18 is connected to the water pipe.

The drawing positions of the water pipe 17 and the drain pipe 18 are difficult to change. For this reason, it is in a state in which it cannot be determined which insertion part 33 the water pipe 17 and the drain pipe 18 are inserted. However, by using the tube holding sleeve 36, the drain tube 18 can be held by the insertion portion 33 even if the drain tube 18 is pulled out from any insertion portion 33. Therefore, it is not necessary to install the water pipe 17 and the drain pipe 18 in consideration of the pipe diameter, and the installation work can be performed quickly.

  (4) Since the water pipe 17 is directly held by the insertion portion 33, two types of resin pipes (water pipe 17 and drain pipe 18) having different pipe diameters are inserted by using the pipe holding sleeve 36. The portion 33 can be held.

  (5) The tube holding sleeve 36 includes a cylindrical body portion 37 and a locking portion 38. When the locking portion 38 is locked to the opening end of the insertion portion 33, the tube holding sleeve 36 and the thick portion 33a of the insertion portion 33 are stopped. The water part 37a was made to oppose. For this reason, by locking the locking portion 38 to the open end, the tube holding sleeve 36 can be disposed at a predetermined position of the insertion portion 33, and the press-fitting operation of the tube holding sleeve 36 can be easily performed. Can do.

  (6) In the installation tool 10, in the configuration in which the diameters of the three insertion portions 33 are the same, the drainage pipe 18 that is thinner than the diameter of the insertion portion 33 is held by the insertion portion 33 by using the tube holding sleeve 36. be able to.
