[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a water supply outlet according to one embodiment of the present invention will be described. 1 will be described as the front-to-back direction of water supply outlet 21, the left-to-right direction of water supply outlet 21, and the up-to-down direction of water supply outlet 21. Therefore, in drawings other than FIG. 1, the directions on the paper may not match the directions indicated in the following description.

[0010] 1 to 5, in a building, a wall 11 of a room in which a washing machine (not shown) as equipment is installed has an opening 12 penetrating the wall 11 in the front-to-rear direction. Opening 12 has a perfect circle shape when viewed from the front, and can be easily constructed with a hole saw or the like, compared to, for example, a square shape when viewed from the front.

[0011] As shown in Figs. 2 to 4, a pillar 13 extending in the vertical direction is disposed behind a wall 11 of the building. The pillar 13 passes near the left side of the opening 12. A water supply pipe 15 serving as a water supply member is laid behind the wall 11. The water supply pipe 15 is made of a synthetic resin such as cross-linked polyethylene or polybutene. The water supply pipe 15 extends in the vertical direction from below the opening 12, i.e., from the floor side of the room, to the opening 12.

[0012] 1, a water supply hose 16 connected to a washing machine is disposed on the front side of the wall 11. A hose side coupler 17 having a known configuration is attached to the end of the water supply hose 16.

[0013] As shown in Fig. 6, a water supply outlet 21 is attached to opening 12 of wall 11. Water supply outlet 21 directs water received from water supply pipe 15 to the front side of wall 11, and then supplies the water to the washing machine via water supply hose 16 (see Fig. 1).

[0014] As shown in Fig. 7, water supply outlet 21 has a water faucet 22 which mainly guides water to the washing machine. Water faucet 22 has a valve portion 31A. Valve portion 31A has a valve housing 41 made of synthetic resin and having a roughly cylindrical shape. A spindle chamber 42 is provided within the front end portion of valve housing 41. Spindle chamber 42 is cylindrical with a bottom and extends in a direction along axis L of valve housing 41. A female thread 42a is provided on the inner circumferential surface of the front end portion of spindle chamber 42.

[0015] An inflow passage 43 is provided in the rear end of the valve housing 41. The inflow passage 43 extends in a direction along the axis L of the valve housing 41. An outlet 43a of the inflow passage 43 is provided in the rear end face of the spindle chamber 42. A valve seat 42b is provided in the spindle chamber 42 around the outlet 43a.

[0016] 11, a square plate-shaped flange 44 is integrally provided on the outer circumferential surface of the rear end of the valve housing 41. Screw holes 44a are provided at each of the four corners of the flange 44. A positioning recess 44b is provided on the right edge of the flange 44.

[0017] A cylindrical inner tube portion 45 is integrally provided on the rear surface of the flange 44 to protrude therefrom. The inner tube portion 45 extends in a direction along the axis L. An accommodation groove 45a is provided on the outer circumferential surface of the inner tube portion 45. The accommodation groove 45a has an annular shape centered on the axis L. A seal ring 46 is accommodated in the accommodation groove 45a. An inlet 43b of the inlet passage 43 is provided on the rear end surface of the inner tube portion 45.

[0018] A pair of left and right first engagement protrusions 41a and a pair of left and right second engagement protrusions 41b are provided on the outer circumferential surface of the rear end of the valve housing 41. Only the right side of the first engagement protrusions 41a and the second engagement protrusions 41b are shown in the figure.

[0019] The faucet 22 has a receiving-side joint 32. The receiving-side joint 32 has a joint body 51 that is separate from the valve housing 41. The joint body 51 is made of synthetic resin and is a so-called elbow that is bent at a right angle. A rib 51a is curved and provided on the radially outer side of the bend in the joint body 51, extending from the upper end side to the lower end side.

[0020] A joint internal passage 52 is provided within the joint body 51. An outer cylinder portion 53 is provided at an upper end portion of the joint body 51 facing the valve housing 41. An outlet 52a of the joint internal passage 52 is provided on the front surface of the outer cylinder portion 53.

[0021] 6, a well-known one-touch joint 54 equipped with a lock ring 54a and the like is provided at the lower end of the joint body 51 facing the floor. The water supply pipe 15 is connected to the one-touch joint 54, which also serves as the inlet of the joint internal passage 52.

[0022] As shown in Fig. 11, a square plate-shaped flange 55 is integrally provided on the outer peripheral surface of the front edge of the outer tubular portion 53. The flange 55 has approximately the same vertical width and a wider horizontal width than the flange 44 of the valve housing 41. First screw holes 55a are provided at the four corners of the flange 55. Second screw holes 55b are provided near the four corners of the flange 55, respectively, on the inside in the horizontal direction of the corresponding first screw holes 55a. A positioning protrusion 55c is provided on the front surface of the flange 55 to the right of the outlet 52a of the fitting internal passage 52.

[0023] As shown in FIG. 12, on the rear surface of the flange 55, pockets 55d are provided at positions corresponding to the second screw holes 55b (see FIG. 11).

[0024] 7, the inner cylinder 45 of the valve portion 31A is inserted into the outer cylinder 53 of the water-receiving side joint 32. With the inner cylinder 45 inserted into the outer cylinder 53, a seal ring 46 ensures watertightness between the outer circumferential surface of the inner cylinder 45 and the inner circumferential surface of the outer cylinder 53, in other words, the connection portion between the joint inner passage 52 and the inflow passage 43. With the inner cylinder 45 inserted into the outer cylinder 53, the flange 44 of the valve portion 31A and the flange 55 of the water-receiving side joint 32 overlap in the front-rear direction.

[0025] 10 and 11, when the flanges 44 and 55 are overlapped, the position of the screw hole 44a of the flange 44 and the position of the second screw hole 55b of the flange 55 are aligned in the up-down and left-right directions. When the flanges 44 and 55 are overlapped, the position of the positioning recess 44b of the flange 44 and the positioning protrusion 55c of the flange 55 are aligned in the up-down and left-right directions, and the positioning recess 44b and the positioning protrusion 55c are fitted together.

[0026] When the flanges 44 and 55 are overlapped, the valve portion 31A and the receiving side joint portion 32 are fixed to each other by screwing a screw 56 passed from the screw hole 44a to the second screw hole 55b into a nut 57 held immovably in a pocket 55d of the flange 55 (see Figure 12).

[0027] Furthermore, even if one attempts to fasten the receiving-side joint 32 and the valve portion 31A together with the opening of the one-touch joint 54 facing upward, in other words with the opening of the one-touch joint 54 facing the ceiling of the room, the position of the positioning recess 44b of the flange 44 and the positioning protrusion 55c of the flange 55 do not match in the left-right direction. Therefore, the positioning recess 44b and the positioning protrusion 55c cannot be fitted together, the flange 44 and the flange 55 cannot be superimposed, and the connection between the valve portion 31A and the receiving-side joint 32 is impossible.

[0028] In such a case, if the positioning protrusion 55c is removed from the flange 55, the receiving-side joint 32 will no longer have a vertical directionality when connected to the valve portion 31A, making it possible to provide a temporary solution. However, if the positioning protrusion 55c is removed from the flange 55, when stress acts between the valve portion 31A and the receiving-side joint 32 in a direction causing relative rotation about the axis L, the stress cannot be borne by the mating portion between the positioning recess 44b and the positioning protrusion 55c, and the load on the screw hole 44a, the second screw hole 55b, the screw 56, etc. increases.

[0029] To solve this problem, it is sufficient to use a valve portion 31B having a configuration shown in Figures 20 and 21. The only difference between the valve portion 31B and the valve portion 31A shown in Figure 11 is the position of the positioning recess 44b in the flange 44, and the other configurations are the same. That is, the positioning recess 44b of the valve portion 31B is provided on the left edge of the rear surface of the flange 44.

[0030] Therefore, when the opening of one-touch joint 54 faces upward, in other words when the opening of one-touch joint 54 faces the ceiling of the room, the position of positioning recess 44b of flange 44 and the position of positioning protrusion 55c of flange 55 are aligned in the vertical and horizontal directions, and the water-receiving joint 32 and valve unit 31B can be connected. Therefore, when the water supply pipe 115 extends above opening 12, that is, from the ceiling side of the room, in the vertical direction to opening 12, valve unit 31B can be appropriately adapted.

[0031] As shown in Fig. 7, the faucet 22 has a water supply side joint 33. A cylindrical protrusion 61 that constitutes the water supply side joint 33 is provided integrally with the valve housing 41 below the front end of the valve housing 41. The protrusion 61 is inclined diagonally downward toward the front side. A male thread 61a is provided on the outer circumferential surface of the protrusion 61.

[0032] An outflow passage 62 is provided within the protruding portion 61. A check valve 63 having a known structure is housed in the outflow passage 62. An inlet 62a of the outflow passage 62 is provided below the valve seat 42b on the inner circumferential surface of the spindle chamber 42. An outlet 62b of the outflow passage 62 is provided on the lower end surface of the protruding portion 61.

[0033] A stop coupler 64 constituting the water supply side joint 33 is detachably attached via a female thread 64a to the male thread 61a of the protrusion 61. The stop coupler 64 has a well-known structure, which allows easy attachment and detachment of the hose side coupler 17 (see FIG. 1), and also has an emergency water stop function in case the hose side coupler 17 becomes unintentionally detached.

[0034] The valve portion 31A includes a cylindrical spindle 47 made of synthetic resin. A male thread 47a is provided on the outer peripheral surface of the front end of the spindle 47. A connecting recess 47b is provided on the front end surface of the spindle 47. A connecting groove 47c extending along the axis L is provided on the inner peripheral surface of the connecting recess 47b. Although not shown, a plurality of connecting grooves 47c are provided at intervals around the axis L. An accommodation groove 47d is provided on the outer peripheral surface of the rear end of the spindle 47. The accommodation groove 47d has an annular shape centered on the axis L. A seal ring 48 is accommodated in the accommodation groove 47d.

[0035] A threaded hole 47e is provided in the rear end face of the spindle 47. A packing 49 serving as a valve body is attached to the spindle 47 by a tapping screw 50 that is screwed into the threaded hole 47e. The spindle 47 is housed in the spindle chamber 42 with the packing 49 facing the valve seat 42b. A seal ring 48 ensures watertightness between the outer peripheral surface of the rear end of the spindle 47 and the inner peripheral surface of the spindle chamber 42.

[0036] With the spindle 47 housed in the spindle chamber 42, the male thread 47a of the spindle 47 is screwed into the female thread 42a of the spindle chamber 42. The screwing of the male thread 47a into the female thread 42a allows the spindle 47 to screw into the spindle chamber 42. Therefore, the spindle 47 is rotated about the axis L of the valve housing 35 and is simultaneously moved in the front-rear direction along the axis L relative to the spindle chamber 42.

[0037] As the spindle 47 moves forward and backward, the packing 49 is displaced between a fully open position (the state shown in FIG. 7) where it is separated from the valve seat 42b and a fully closed position (the state shown in FIG. 8) where it is in contact with the valve seat 42b. As shown in FIG. 7, the packing 49 in the fully open position fully opens the outlet 43a of the inflow passage 43, fully opening the water passage between the outlet 43a and the inlet 62a of the outflow passage 62. As shown in FIG. 8, the packing 49 in the fully closed position blocks the outlet 43a of the inflow passage 43, fully closing the water passage between the outlet 43a and the inlet 62a of the outflow passage 62.

[0038] As shown in Figures 2 to 5, water supply outlet 21 includes support member 23 made of synthetic resin that supports water faucet 22 on pillar 13. As shown in Figure 9, support member 23 is integrally provided with rectangular back plate 71 located on the rear side, side walls 72 provided on the left and right edges of the front surface of back plate 71, and upper wall 73 provided on the upper side of the front surface of back plate 71. Storage space 74 surrounded by back plate 71, both side walls 72, and upper wall 73 is provided with engagement groove 74a that curves forward as it moves from the lower side to the upper side.

[0039] Each side wall 72 is provided with a vertical member screw hole 72a and a horizontal member screw hole 72b. A back plate 71 is provided with a back member screw hole 71a. As shown in Figs. 2 to 5, the vertical member screw hole 72a provided in the left side wall 72 corresponds to the pillar 13. In other words, the support member 23 is attached to the pillar 13 via a screw (not shown) inserted into the vertical member screw hole 72a.

[0040] Although not shown, if the pillar is located on the right side wall 72 side, the support member 23 is attached to the pillar using the vertical member screw hole 72a provided in the right side wall 72. If the pillar extends horizontally, the support member 23 is attached to the pillar using the horizontal member screw hole 72b provided in both side walls 72. Furthermore, if the pillar passes through the rear side of the support member 23, the support member 23 is attached to the pillar using the back member screw hole 71a provided in the back plate 71.

[0041] 9, a pair of upper and lower first screw holes 72c are provided in the front end surface of each side wall 72. A pair of upper and lower second screw holes 72d are provided in the front end surface of each side wall 72. In each side wall 72, the pair of second screw holes 72d are disposed between the upper first screw hole 72c and the lower first screw hole 72c.

[0042] An engagement wall 72e is provided on the front end surface of each side wall 72, extending forward and closer to the edge than the first screw hole 72c and the second screw hole 72d. An engagement protrusion 72f is provided on the side surface of each engagement wall 72e opposite the other engagement wall 72e (only the engagement protrusion 72f on the right side is shown). A slit 72g extending in the vertical direction is provided on the front end surface of each side wall 72, between the upper second screw hole 72d and the lower second screw hole 72d.

[0043] 6, the receiving-side joint 32 of the faucet 22 is accommodated in the accommodation space 74 of the support member 23. When the receiving-side joint 32 is accommodated in the accommodation space 74, the flange 55 of the receiving-side joint 32 overlaps with each side wall 72 of the support member 23 at its front end surface.

[0044] 10, when the flange 55 and each side wall 72 are overlapped, the position of the first screw hole 55a of the flange 55 and the position of the second screw hole 72d of the corresponding side wall 72 are aligned in the up-down and left-right directions. The faucet 22 is fixed to the support member 23 by tapping screws 75 passed through the first screw holes 55a and the second screw holes 72d.

[0045] As shown in Fig. 7, when the receiving joint 32 is accommodated in the accommodation space 74, the rib 51a of the receiving joint 32 is inserted into the engagement groove 74a of the accommodation space 74. Therefore, for example, when stress is applied to the faucet 22, the stress is also received by the engagement groove 74a via the rib 51a, so that the stress acting on the tapping screw 75 (see Fig. 10) can be reduced. Furthermore, even before the tapping screw 75 is screwed in, the faucet 22 can be positioned relative to the support member 23, so the operation of screwing in the tapping screw 75 can be performed stably.

[0046] As shown in Fig. 14, in a front view of the support member 23 fixed to the pillar 13, the first screw hole 72c, the second screw hole 72d (see Fig. 10), the engagement wall 72e, the slit 72g (see Fig. 10), etc. are positioned within the opening 12 of the wall 11. In a front view of the faucet 22 fixed to the support member 23, the valve housing 41 (see Fig. 10), the flange 44, the flange 55, etc. are positioned within the opening 12 of the wall 11.

[0047] Also, as shown in Figure 6, the faucet 22 fixed to the support member 23 has the spindle 47 side portion of the valve portion 31A and the water supply side joint portion 33 protruding forward beyond the wall 11 through the opening 12.

[0048] As shown in Fig. 2, the water supply outlet 21 has a decorative plate 24 that is disposed on the front side of the wall 11 and covers the opening 12. As shown in Fig. 9, the decorative plate 24 has a rectangular plate-shaped base 81 made of synthetic resin. A through hole 81a is provided in the base 81. The through hole 81a extends from near the upper edge of the base 81 to near the lower edge in the shape of an elongated hole that first widens into a circular hole in the center.

[0049] A pair of screw holes 81b are provided on the left and right sides of the through hole 81a in the base 81. A rectangular plate-shaped mounting piece 81c is provided on the left and right sides of the through hole 81a on the rear surface of the base 81. An engagement hole 81d is provided near the left and right edges of the base 81.

[0050] The base 81 is superimposed on the front surface of the wall 11, and covers a part of the opening 12. When the base 81 is superimposed on the wall 11, the mounting piece 81c of the base 81 is inserted into the corresponding slit 72g of the support member 23 through the opening 12. When the base 81 is superimposed on the wall 11, the position of the screw hole 81b of the base 81 and the position of the corresponding first screw hole 72c of the support member 23 are aligned in the up-down and left-right directions. The base 81 and the support member 23 are fixed to each other via the wall 11 by a long screw 82 passed from the screw hole 81b to the first screw hole 72c.

[0051] The decorative plate 24 includes a decorative member 83 made of synthetic resin. The decorative member 83 is a rectangular plate slightly larger than the base 81. The decorative member 83 is provided with an insertion hole 83a. The insertion hole 83a is a circular hole in the center of the decorative member 83 and extends in an elongated hole shape toward the lower edge, so that the overall shape is a keyhole when viewed from the front. A rib 83b is provided on the rear surface of the decorative member 83 along the inner edge of the insertion hole 83a. Engagement pieces 83c with hook-shaped tips are provided on the rear surface of the decorative member 83 near the left and right edges.

[0052] 1, a symbol 83d indicating the fully open state of the faucet 22 is drawn to the left of the insertion hole 83a on the front surface of the decorative member 83. A symbol 83e indicating the fully closed state of the faucet 22 is drawn to the right of the insertion hole 83a on the front surface of the decorative member 83.

[0053] 7, the decorative member 83 is superimposed on the base 81 and covers the entire front surface of the base 81. As shown in Fig. 9, the decorative member 83 is detachably fixed to the base 81 by snap-engagement of an engagement piece 83c with an engagement hole 81d of the base 81.

[0054] 7, when the decorative member 83 is fixed to the base 81, the rib 83b of the decorative member 83 fits into the through hole 81a of the base 81. Therefore, when the insertion hole 83a of the decorative member 83 is viewed from the front, the inner edge of the through hole 81a of the base 81 is hidden by the rib 83b and is difficult to see. In other words, the rib 83b enhances the decorativeness of the decorative member 83.

[0055] When the decorative plate 24 is attached to the support member 23, the spindle 47 side portion of the valve portion 31A of the faucet 22 and the water supply side joint portion 33 protrude forward beyond the decorative plate 24 through the insertion hole 83a.

[0056] The through-hole 81a of the base 81 is provided from the vicinity of the center to the vicinity of the upper edge in order to make the through-hole 81a symmetrical in the up-down direction. Therefore, the base 81 has no directionality with respect to the support member 23 in the up-down direction.

[0057] As shown in Figures 7 and 10, the water supply outlet 21 includes a decorative cover 26 that is attached to the faucet 22 and covers the faucet 22. The decorative cover 26 includes a main cover 91 that is attached to the valve housing 41. The main cover 91 includes a main body 92 that is cylindrical and centered on the axis L, and a rectangular portion 93 that protrudes below the main body 92. The rectangular portion 93 communicates with the main body 92 through an internal space and is open to the lower and rear sides. The main body 92 mainly covers the valve portion 31A. The rectangular portion 93 mainly covers the protruding portion 61 of the water supply side joint 33.

[0058] A small diameter portion 94 having an opening (94a) facing forward is provided at the front end of the main body 92. A flange 94b is provided in the opening 94a of the small diameter portion 94 in an annular shape centered on the axis L. A restricting protrusion 94c extending a predetermined length in the circumferential direction is provided on the front surface of the flange 94b.

[0059] 10, a pair of left and right engagement holes 92a (only the right engagement hole 92a is shown) is provided at the rear end of the main body 92. The main cover 91 is detachably fixed to the valve housing 41 by snap-engagement of the corresponding first engagement projections 41a of the valve housing 41 with each engagement hole 92a.

[0060] The decorative cover 26 is provided with a sub-cover 95. The sub-cover 95 covers the lower opening of the rectangular portion 93 of the main cover 91. A pair of left and right engagement protrusions 95a with hook-shaped tips are provided on the upper end surface of the sub-cover 95. The engagement protrusions 95a snap-engage with the second engagement protrusions 41b of the valve housing 41, thereby removably fixing the sub-cover 95 to the valve housing 41. The sub-cover 95 does not cover the entire protrusion 61, leaving the male thread 61a and the outlet 62b exposed.

[0061] As shown in Fig. 7, the valve portion 31A includes a disk-shaped non-rising plate 27 made of synthetic resin. The non-rising plate 27 is disposed within the decorative cover 26, between the flange 94b of the main cover 91 and the valve housing 41 of the faucet 22. A connecting protrusion 27a is provided on the rear surface of the non-rising plate 27. A connecting ridge 27b extending along the axis L is provided on the outer peripheral surface of the connecting ridge 27a. Although not shown, multiple connecting ridges 27b are provided around the axis L.

[0062] The connecting protrusion 27a of the non-rising plate 27 is inserted into the connecting recess 47b of the spindle 47. The connecting protrusion 27b of the non-rising plate 27 is inserted into the connecting recess 47c of the spindle 47.

[0063] Therefore, when the non-rising plate 27 is rotated about the axis L, the spindle 47 is also rotated in the same direction via the connecting ridges 27b and the connecting recesses 47c. However, since the connecting recesses 47c and the connecting ridges 27b are capable of relative movement in the direction along the axis L, the non-rising plate 27 does not follow the movement of the spindle 47 in the direction along the axis L. This type of structure is called a "non-rising mechanism."

[0064] 10, a frame-shaped rib 27c with a portion spaced apart is provided on the front surface of the non-rising plate 27. A screw hole 27d is provided in the center of the non-rising plate 27.

[0065] 7, the portion of the non-rising plate 27 on the front surface that is outer circumferential side of the rib 27c abuts against the flange 94b of the main cover 91, thereby preventing the connecting protrusion 27a from slipping out of the connecting recess 47b of the spindle 47. The rib 27c and the screw hole 27d of the non-rising plate 27 are located within the opening 94a of the small diameter portion 94 of the main cover 91 in a front view.

[0066] As shown in Figs. 7 and 10, the water supply outlet 21 has a handle 25 as an operating member for operating the water faucet 22. The handle 25 is made of synthetic resin. The handle 25 has a main body 97 having a cylindrical shape with a lid and a lever portion 98 protruding from the outer circumferential surface of the main body 97. A connecting protrusion 97a is provided at the center of the back surface of the lid of the main body 97. The connecting protrusion 97a has a shape in which a part of the outer periphery protrudes in the radial direction. A restricting protrusion 97b is provided at the outer periphery of the back surface of the lid of the main body 97. A screw hole 97c is provided at the center of the main body 97. An accommodating recess 97d is provided at the opening of the screw hole 97c at the front end face of the main body 97. A cap 99 is detachably press-fitted into the accommodating recess 97d.

[0067] The handle 25 is arranged with the main body 97 fitted onto the small diameter portion 94 of the decorative cover 26. The connecting protrusion 97a of the handle 25 is inserted into the rib 27c so that the radially protruding portion enters the interrupted portion of the rib 27c of the non-rising plate 27. The screw 100 inserted into the screw hole 97c of the handle 25 is screwed into the screw hole 47e of the spindle 47 via the screw hole 27d of the non-rising plate 27. The head of the screw 100 is accommodated in the accommodation recess 97d and is hidden by the cap 99.

[0068] When the handle 25 is rotated about the axis L, the non-rising plate 27 is also rotated in the same direction via the connecting protrusion 97a and the rib 27c. When the non-rising plate 27 is rotated, the spindle 47 is also rotated in the same direction, and the packing 49 is displaced between the fully open position and the fully closed position. Rotation of the handle 25 beyond a predetermined range is restricted by the restricting protrusion 97b abutting against either one end face in the circumferential direction of the restricting protrusion 94c of the decorative cover 26.

[0069] Next, the process of attaching the water supply outlet 21 to the opening 12 in the wall 11 will be described.

[0070] Fig. 13 shows the state after the pillar 13 has been installed and before the wall 11 has been attached. The water supply outlet 21 is in a semi-finished state with the decorative plate 24, handle 25, and stop coupler 64 removed from the completed state shown in Fig. 2 (hereinafter referred to as the "water supply outlet (semi-finished) 21"). The water supply outlet (semi-finished) 21 is fixed to the pillar 13. A water supply pipe 15 is connected to the water supply outlet (semi-finished) 21.

[0071] A protective cover 101 is attached to the water supply outlet (semi-finished) 21 so as to cover the decorative cover 26. The protective cover 101 is attached to the water supply outlet (semi-finished) 21 at the time of shipping from the factory. The protective cover 101 protects the decorative cover 26 and the like from direct impact when the water supply outlet (semi-finished) 21 collides with something during transportation, storage, installation, etc.

[0072] The protective cover 101 has a cylindrical shape with a lid. The protective cover 101 has a tapered shape in which the outer diameter becomes smaller toward the front side. The tapered protective cover 101 makes it easy to store multiple protective covers 101 stacked together. The maximum outer diameter of the protective cover 101 is smaller than the inner diameter of the opening 12 of the wall 11.

[0073] As shown in Fig. 14, an engagement recess 101a extending along the axis L is provided on the outer circumferential surface of the protective cover 101. Therefore, as shown in Fig. 13, an engagement protrusion 101b is provided on the inner circumferential surface of the protective cover 101 at a position corresponding to the rear side of the engagement recess 101a. The engagement recess 101a makes it easier for an operator to grip the protective cover 101. When multiple protective covers 101 are stacked, the engagement protrusion 101b is received in the engagement recess 101a of another protective cover 101, making it easier to align the circumferential orientations of the multiple protective covers 101 with each other.

[0074] A plurality of (four in this embodiment) engaging recesses 101a and engaging protrusions 101b are provided at intervals in the circumferential direction. A lid portion 101c is provided on the rear edge of each engaging recess 101a. The lid portion 101c closes the rear opening of the corresponding engaging recess 101a.

[0075] 14, an engagement wall 102 is provided on the rear end face of the protective cover 101 so as to protrude rearward. An upper and lower pair of engagement walls 102 and a left and right pair of engagement walls 102 are disposed at positions shifted in the circumferential direction with respect to the engagement recess 101a (only the upper and right engagement walls 102 are shown). An engagement hole 102a is provided in each of the pair of left and right engagement walls 102.

[0076] The protective cover 101 is attached to the support member 23 such that a pair of engagement walls 72e of the support member 23 are positioned between a pair of left and right engagement walls 102. In the protective cover 101, the engagement protrusions 72f of the corresponding engagement walls 72e of the support member 23 are snap-engaged with the engagement holes 102a of the respective engagement walls 102. The protective cover 101 is detachably fixed to the support member 23 by the snap engagement between the engagement walls 102 and 72e. The front side of the first screw hole 72c is covered by a lid portion 101c of the protective cover 101. The lid portion 101c prevents the first screw hole 72c from being soiled or damaged.

[0077] 13, after a water supply outlet (semi-finished) 21 is attached to a pillar 13 and a water supply pipe 15 is connected to the water supply outlet (semi-finished) 21, a wall 11 having an opening 12 is attached. When attaching the wall 11, the front end of the protective cover 101 is inserted from the rear opening of the opening 12. With the wall 11 attached, the protective cover 101 is inserted through the opening 12, and the front end of the protective cover 101 protrudes forward from the front opening of the opening 12.

[0078] As shown in FIG. 14, after the wall 11 is attached, the protective cover 101 is removed from the water supply outlet (semi-finished) 21. The protective cover 101 is removed by releasing the snap engagement between the engagement wall 102 of the protective cover 101 and the engagement wall 72e of the support member 23. As described above, the maximum outer diameter of the protective cover 101 is smaller than the inner diameter of the opening 12 of the wall 11. Therefore, by utilizing the gap caused by the diameter difference, the snap engagement between the protective cover 101 and the support member 23 can be easily released from the front side of the opening 12. In addition, due to the diameter difference, the protective cover 101, whose snap engagement has been released, can be easily taken out from the opening 12 to the front side of the wall 11.

[0079] As shown in Figure 15, with the protective cover 101 removed, the decorative plate 24 is attached to the water supply outlet (semi-finished) 21 from the front side of the wall 11, in the order of base 81 and decorative member 83. In the water supply outlet (semi-finished) 21 with the decorative plate 24 attached, the portion of the valve section 31A facing the non-rising plate 27 and the water supply side joint section 33, together with part of the decorative cover 26 that covers them, protrude forward from the decorative plate 24 through the insertion hole 83a (see Figure 2).

[0080] 2, the thickness of the wall 11 is relatively small. Therefore, the distance between the support member 23 and the decorative plate 24 in the front-rear direction is narrow, and the amount by which the decorative cover 26 protrudes forward from the decorative plate 24 is large. However, the decorative cover 26 is long in the front-rear direction of the wall 11, and the rear end of the decorative cover 26 is contained within the insertion hole 83a of the decorative plate 24. Therefore, when the insertion hole 83a is viewed from the front, the valve housing 41 of the valve portion 31A and the like are hidden by the decorative cover 26 and are difficult to see, and the decorativeness of the decorative cover 26 is maintained.

[0081] As shown in Figures 2 and 15, a handle 25 and a stop coupler 64 are attached to the front side of the wall 11 to the water supply outlet (semi-finished) 21 with the decorative plate 24 attached, thereby completing the water supply outlet 21.

[0082] Next, maintenance of the water supply outlet 21 attached to the opening 12 will be described.

[0083] Examples of such maintenance include spindle replacement and valve unit replacement. Spindle replacement is performed by removing spindle 47 from valve unit 31A while valve unit 31A and receiving-side joint unit 32 remain fixed to each other. Valve unit replacement is performed by removing valve unit 31A from receiving-side joint unit 32.

[0084] 17, in both the spindle replacement work and the valve replacement work, the handle 25 and the stop coupler 64 are removed in the reverse order to the installation process of the water supply outlet 21 described above, and the decorative member 83 is removed from the base 81 in the decorative plate 24. With the decorative member 83 removed from the base 81, the gap between the inner edge of the through hole 81a and the outer circumferential surface of the main cover 91 is exposed to the front side.

[0085] The snap engagement between the valve housing 41 and the main cover 91 is released from the front side of the wall 11 by utilizing the gap between the inner edge of the through hole 81a and the outer circumferential surface of the main cover 91. The main cover 91, whose snap engagement with the valve housing 41 has been released, is removed from the through hole 81a of the base 81 to the front side of the wall 11. By removing the main cover 91, almost the entire front side of the non-rising plate 27 is exposed.

[0086] When performing spindle replacement work from this state, as shown in Fig. 18, the non-rising plate 27 is removed from the spindle 47, and the spindle 47 is removed together with the packing 49 from the valve housing 41. The removed spindle 47 is replaced with one having a new packing 49 attached, and after it is attached to the valve housing 41, the non-rising plate 27 is attached.

[0087] When replacing the valve portion, as shown in Fig. 19, the screw 56 is removed from the front side of the wall 11 by utilizing the gap between the inner edge of the through hole 81a and the outer circumferential surface of the valve housing 41. By removing the screw 56, the valve portion 31A and the receiving-side joint portion 32 (see Fig. 11) are released from their fixation. The valve portion 31A, which has been released from their fixation to the receiving-side joint portion 32, is taken out together with the sub-cover 95 from the through hole 81a of the base 81 to the front side of the wall 11. The non-rising plate 27 and the sub-cover 95 of the taken-out valve portion 31A are removed and replaced with new ones, and the non-rising plate 27 and the sub-cover 95 are reinstalled, and then the valve portion 31A is attached to the receiving-side joint portion 32.

[0088] After the above-mentioned spindle replacement work or valve unit replacement work is completed, the main cover 91, the decorative member 83, the handle 25, and the stop coupler 64 are respectively attached in the reverse order.

[0089] Next, water supply outlet 21 attached to opening 112 of wall 111 that is thicker than wall 11 will be described.

[0090] As shown in Figure 16, the water supply outlet 21 attached to the opening 112 of the wall 111 has a wide distance between the support member 23 and the decorative plate 24 in the front-to-rear direction, and the decorative cover 26 only protrudes a small amount forward from the decorative plate 24. Therefore, the rear end of the decorative cover 26 protrudes significantly rearward from the insertion hole 83a of the decorative plate 24, and naturally, when the insertion hole 83a is viewed from the front, the valve housing 41 of the valve portion 31A (see Figure 10) and the like are hidden by the decorative cover 26, making them even more difficult to see.

[0091] 2 and 16, the relative positions of the decorative plate 24 and the faucet 22 to which the decorative cover 26 is attached can be adjusted within a predetermined range in the front-to-rear direction of the wall 11, 111 in accordance with the thickness of the wall 11, 111. Furthermore, the decorative cover 26 is provided long in the front-to-rear direction of the wall 11, 111 so that the faucet 22 can be covered between the handle 25 and the decorative plate 24 at any adjustment position within the predetermined range, making it possible to change the amount of protrusion of the decorative cover 26 from the insertion hole 83a toward the front side of the wall 11, 111.

[0092] Therefore, with the water supply outlet 21 of this embodiment, there is no need to go to the trouble of determining the thickness of the wall 11, 111, choosing whether or not to have spacers and the number of spacers depending on the thickness of the wall 11, 111, and placing spacers between the decorative plate 24 and the wall 11, 111, as occurs in the prior art, making it easy to deal with cases where the thickness of the wall 11, 111 is different.

[0093] As shown in Figures 1, 2, 9, 10 and 16, the outer shape of the portion of the decorative cover 26 that corresponds to the insertion hole 83a of the decorative plate 24 within the specified range has a keyhole shape that follows the keyhole shape of the insertion hole 83a and extends in the direction along the axis L.

[0094] 2 and 16, the gap between the inner edge of the insertion hole 83a of the decorative plate 24 and the portion of the decorative cover 26 located within the insertion hole 83a can be kept constant at any adjustment position within the predetermined range. Therefore, even if the thicknesses of the walls 11, 111 are different, the appearance near the gap can be kept constant.

[0095] "Another example" The above embodiment can be modified as follows. The decorative plate 24 is fixed directly to the wall 11, 111, rather than to the support member 23.

[0096] The support member 23 is fixed directly to the wall 11, 111, not to the pillar 13.

[0097] The water supply outlet 21 can be attached to the opening 12 by sandwiching the walls 11, 111 between the decorative plate 24 and the support member 23.

[0098] The base 81 may be omitted from the decorative plate 24 and the decorative member 83 may be fixed directly to the support member 23.

[0099] The base 81 of the decorative plate 24 is disc-shaped.

[0100] The decorative plate 24 (base 81 and decorative member 83) is disc-shaped.

[0101] The main cover 91 of the decorative cover 26 is formed in a rectangular tube shape.

[0102] In the decorative cover 26, the main cover 91 and the sub-cover 95 are integrated into one piece.

[0103] The non-rising plate 27 may be eliminated and the handle 25 and the spindle 47 may be directly connected.

[0104] The valve sections 31A and 31B are ball valves.

[0105] The valve sections 31A and 31B may be electrically driven valves such as solenoid valves.
