FIGS. 18 and 19 are cross-sectional views showing the steps of a further embodiment of the present invention. This example is based on the first
It is similar to the embodiment shown in FIGS. 7 to 7, and corresponding parts are provided with the same reference numerals. It should be noted that in this example,
Guide tube 38 is synthetic! A guide cylinder 38 having such a structure includes a right cylindrical cylinder main body 39 made of a material such as lubricant, and a band 40 made of paper partially wound around the outer periphery of this cylinder main body 39. , is fitted into the mounting tube 17 of the mounting member 15, and the wall plate 13 is fixed with the flexible tube 21 inserted into the guide tube 38. When ``4@13'' is tiled or made of mortar, the inner circumferential surface of the mounting hole 24 will be in close contact with the outer circumferential surface of the band 40.

Therefore, when fixing the cock 25 etc. to the wall board 13, before pulling out the guide fj13B, first unwind the band 40. Cut the band 40 from paper etc. as described above, and cut the outer periphery of this band 40. Even if the surface 21 is attached to the wall plate 13, the band 40 can be taken out from the mounting hole 24 by tearing off the band 40. In this way, a gap δ exists between the inner circumferential surface of the attachment hole 24 and the outer circumferential surface of the cylinder body 39.

Therefore, in this state, the guide tube 39 can be easily pulled out from the attachment tube 17 of the attachment member 15.

FIG. 20 is a sectional view illustrating the steps of another embodiment of the present invention. In this embodiment, the mounting member 41 has a disk-shaped substrate 42 on the front side, as shown in the rpJ21 diagram.

The mounting piece 44 consists of a mounting cylinder part 45 into which the base end of the guide cylinder 19 fits, and a seven-runway part 46 that expands outward. The cover piece 43 includes a cover part 47 that sandwiches the 7-run part 46 with the board 42, and a fixing part 48 that is fixed to the board 42.
It consists of An opening 49 is formed in the cover portion 47 . The inner diameters of these four openings are larger than the outer diameter of the mounting tube 45, so the mounting piece 44 can be displaced along the surface of the wall plate 12 relative to the base plate 42, that is, along the plane of the paper in FIG. Can be done. Therefore, when the wall plate 13 in which the mounting hole 24 is formed in advance is fixed in a state where the base plate 42 of the mounting member 41 is fixed to the wall plate 12 in advance and the guide ff19 is fitted into the mounting cylinder part 45, Even if the mounting hole 24 is formed at a position shifted from the desired position, the mounting piece 44 and therefore the guide vJ19 can be displaced 3I! along the wall plate 12. It is possible to reliably insert the guide tube 19 into the mounting hole 24 with the alignment.

In this way, there is no need to position the mounting holes 24 of the wall plate 13 with high precision, and work efficiency is improved.
