Description

  The present invention relates to an embedded faucet that can supply water to a water supply hose of a machine such as a washing machine, a water purifier, a dishwasher, and a water heater.

  When installing an embedded faucet that is embedded in a wall, the wall thickness of the installation location is not uniform, so if you do not take any measures to overcome the difference in wall thickness, the faucet body Is fixed to the stud on the back side of the wall, the front surface of the faucet does not uniformly protrude from the opening of the wall to the front side. In this regard, Patent Document 1 describes a technique that responds to the difference in wall thickness by adjusting the number of stacked frame-like spacers provided between the front portion of the housing and the wall (Patent Document 1). 1).

JP 2001-295330 A

  However, in the above prior art, if the spacers per sheet are thick, it becomes difficult to adjust the difference in wall thickness only by the number of spacers, and the amount of protrusion from the wall of the embedded faucet is not uniform, so There is a concern that the later embedded faucet may protrude greatly from the wall or conversely enter the wall. In addition, when trying to cope with a finer difference in wall thickness, it is conceivable to reduce the thickness of the spacer per sheet, but in this case, the number of spacers used may increase, which may adversely affect workability. is there.

  The present invention has been made in view of the above circumstances, and its purpose is to easily improve the state after installation, to improve workability, and to reduce manufacturing costs. It is to provide an embedded faucet that contributes.

In order to achieve the above object, an embedded faucet according to the present invention comprises:
The faucet body,
A holder fixedly arranged on the back side of the wall to hold the faucet body;
A connection tool that is inserted over the holder and the faucet body and connects the holder and the faucet body;
A spacer that is mounted so as to be inserted into a portion between the portion inserted into the holding tool and the portion inserted into the faucet body in the connector and is detachable;
The distance from the part inserted into the holding tool to the part inserted into the faucet body in the connector is changed by the attachment / detachment of the spacer and the change of the length of the spacer to be attached, and the position of the faucet body Is configured to move in the front and back direction of the wall (claim 1).

Further, in the buried faucet, the holder has a holding surface section extending parallel said wall substantially, the connecting device includes: the holding surface section, inserted over said faucet Body, in the faucet body The portion into which the connection tool is inserted may be located on the wall side as viewed from the holding surface portion or on the opposite side (Claim 2).

  The embedded faucet includes a cover that covers a faucet mounting hole provided in the wall, and the cover is locked or fixed to the faucet body or a member connected to the faucet body. It may be held (claim 3).

Furthermore, the embedded faucet
A valve connected to the faucet body;
A cover for covering the faucet mounting hole provided on the wall;
A joint provided on the downstream side of the faucet body;
A flow rate adjustment member connected to the valve and operated from the front side of the cover for adjusting the flow rate of water sent from the joint portion to a water supply hose connected to the joint portion;
The cover may be held by being locked or fixed to the valve, the faucet body or the joint part (Claim 4).

  In the embedded faucet, a spacer having an arbitrary length may be selected and used from the plurality of spacers having different lengths.

  In the invention according to each claim, it is possible to easily improve the state after installation, to improve workability, and to obtain an embedded water faucet that contributes to a reduction in manufacturing cost.

  That is, in the invention according to each claim, the wall of the embedded faucet can be changed by changing the length of the spacer (including attachment / detachment of the spacer) even when the interval between the stud and the wall and the wall thickness vary depending on the construction site. The amount of protrusion to the front side (protrusion amount) can be made uniform, thereby making it easy to improve the state of the embedded faucet after installation, and changing the length of the spacer For example, workability can be improved because it can be performed by simple operations such as selection of a spacer having an appropriate length and attachment / detachment of the spacer.

  In addition, in the invention according to each claim, since the spacer can be made using a small and inexpensive synthetic resin, the case of using a large frame-like spacer or the like used in the above-described conventional embedded water faucet This is more advantageous in terms of reducing manufacturing costs.

  In addition, since the invention according to each claim can eliminate the housing used in the conventional embedded water faucet, this also contributes to cost reduction and is excellent in terms of downsizing the installation space. .

  In the inventions according to claims 3 and 4, the cover is not directly attached to the holder fixedly arranged on the back side of the wall, but the faucet body whose position is adjusted by the spacer and the member connected to the faucet body Since the cover is held by the cover, it is possible to easily install the cover and the embedded water faucet regardless of the wall thickness.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the embedded faucet 1 according to the first embodiment of the present invention has a joint portion 2 and a flow rate adjusting member (for example, a handle) 3 having a substantially rectangular shape in front view. The cover 4 (see also FIG. 6) is provided exposed (protruded) on the front side (outside).

  For example, a joint member C provided at an upstream end of a water supply hose H connected to a water supply target (in the illustrated example, a washing machine) T illustrated in FIG. 1 is detachably connected to the joint portion 2. Here, the joint member C is provided with a locking portion C1 that is detachably locked to the flange member 5 of the joint portion 2 (see FIG. 10E). Then, when the joint member C is connected to the joint portion 2, the stop valve (emergency stop valve) 6 of the joint portion 2 is pushed by the joint member C and moves upstream, and enters the valve opening state from the joint portion 2. When water supply to the water supply hose H side becomes possible and the connection of the joint member C to the joint portion 2 is released, the stop valve 6 returns to the original position and the valve is closed. The structure of the stop valve 6 having such a function is known, and a detailed description thereof will be omitted.

  The flow rate adjusting member 3 is operated from the front side of the cover 4 in order to adjust the water supply flow rate from the joint portion 2 provided on the downstream side of the faucet body 7 to the water supply hose H side. The flow rate adjusting member 3 of this embodiment is attached to a valve 9 that is attached to the opening 8 of the faucet body 7 and connected to the faucet body 7 as shown in FIGS. Connected (connected).

  Here, a water supply pipe (not shown) is connected to the faucet body 7 via a pipe connection member 10 (see FIGS. 3A and 4) which is an elbow in this embodiment. Is configured to be rotatable 360 ° around the axis with respect to the faucet body 7.

  On the other hand, as shown in FIGS. 3A and 3B and FIGS. 5A and 5B, the valve 9 includes an inner cylindrical body 11, an outer cylindrical body 12, and a holding body 13, and includes an inner cylindrical body. 11 is rotatably arranged in the outer cylinder 12, and the holding body 13 for holding the inner cylinder 11 and the outer cylinder 12 in a state of being inserted into the opening 8 of the faucet body 7 includes: A male screw 13a that is screwed onto the female screw 8a of the opening 8 is provided. As shown in FIGS. 3A and 3B, the outer cylinder 12 and the holding body 13 are separated by a large-diameter portion 11a and a retaining piece 14 provided on the outer wall of the inner cylinder 11. Mounted on the outside of the cylinder 11.

  Further, the inner cylinder 11 is configured to rotate with the rotation operation of the flow rate adjusting member 3, and a through-hole provided in the side wall of the inner cylinder 11 with the rotation of the inner cylinder 11. 15 (see FIGS. 3A and 3B) and the degree of communication between the through hole 16 provided in the side wall of the outer cylinder 12 (see FIGS. 5A and 5B) is changed. Is reflected in the feed water flow rate from the joint portion 2 to the feed water hose H side.

  That is, the water that has reached the faucet body 7 through the pipe connection member 10 from the water supply pipe proceeds to the inside of the inner cylinder 11 of the valve 9 (see FIG. 3A). And the water which passed through the through-hole 16 of the outer cylinder 12 from the through-hole 15 of the inner cylinder 11 goes to the joint part 2, and is guide | induced into the water supply hose H from the joint part 2. FIG. Therefore, the smaller the degree of communication between the through hole 15 of the inner cylinder 11 and the through hole 16 of the outer cylinder 12, the smaller the water supply flow rate from the joint portion 2 to the water supply hose H side, and the greater the degree of communication, the greater the water supply. The flow rate also increases.

  In the faucet body 7, the flow path portion from the valve 9 to the joint portion 2 includes, for example, water hammer generated on the downstream side of the joint portion 2 (in this example, an electromagnetic valve of a washing machine that is a water supply target T) A check valve 18 having a damper portion 17 for absorbing and mitigating (water hammer generated during the opening / closing operation) is provided (see FIG. 3B). In addition, a sealing member such as an O-ring is provided at an appropriate portion such as the valve 9 in the faucet body 7 to stop water (see FIGS. 3A and 3B). In particular, in this embodiment, the inner cylinder 11 is attached to the annular groove 11b surrounding the through hole 15 and the annular groove 11b, and between the through hole 15 of the inner cylinder 11 and the through hole 16 of the outer cylinder 12. The sealing member 11c for preventing water leakage is provided, and the entire valve 9 is made compact (see FIGS. 3A and 3B).

  And as shown in FIG. 3 (A) and FIG. 4, the faucet body 7 has a front end thereof with respect to a pillar M which is installed (fixedly arranged) on the back side of a wall (board) W and extends in a substantially vertical direction. It is held by a metal (for example, iron) holder 19 attached in a state of being positioned along the front surface of the stud M (or the back surface of the wall W), and is thereby arranged on the back side of the wall W. .

  As shown in FIGS. 3A, 4, and 7 </ b> A to 7 </ b> D, the holder 19 includes a first attachment surface portion 20 that extends in a substantially vertical direction and a direction substantially orthogonal to the wall W, and the first mounting surface portion 20. A second mounting surface portion 21 that is connected to the upper portion of the first mounting surface portion 20 and extends substantially in the horizontal direction; and a holding surface portion 22 that is connected to the front portion of the first mounting surface portion 20 and extends substantially parallel to the wall W. For example, it has a configuration suitable for cold rolled steel plate (SPCC) punching and bending. In addition, bead processing is performed on the bent portion serving as the boundary between the first mounting surface portion 20 and the second mounting surface portion 21 and the bent portion serving as the boundary between the first mounting surface portion 20 and the holding surface portion 22. .

  Each of the first and second mounting surface portions 20 and 21 is provided with, for example, a plurality (two in the illustrated example) of holes 20a and 21a for screwing with screws 23, and the holding surface portion 22 has a connector 24. For example, a plurality (two in the illustrated example) of insertion holes 22a are provided.

  The connector 24 is configured to be inserted over the holder 19 and the faucet body 7 so as to connect the holder 19 and the faucet body 7. Note that the connection tool 24 of this embodiment is a washer built-in screw (so-called Sems screw), and the connection tool 24 is screwed into a portion of the faucet body 7 that is located farther from the holding surface portion 22 with respect to the wall W. An internal thread portion 7a is provided (see FIGS. 3A and 4). In FIG. 4, the illustration of the washer of the connector 24 is omitted.

  Further, as shown in FIGS. 3A and 4, the connector 24 is mounted so as to be inserted into a portion between the portion inserted into the holder 19 and the portion inserted into the faucet body 7. In addition, a spacer 25 made of a synthetic resin (for example, POM) that is detachable is provided. That is, as shown in FIGS. 8A and 8B, the spacer 25 is provided with, for example, a plurality (two in the illustrated example) of insertion holes 25 a through which the connection tool 24 is inserted. The spacer 25 may have, for example, only one insertion hole 25a, and may be configured to avoid other connection tools 24 that do not pass through the insertion hole 25a.

  Here, in this embodiment, a spacer 25 having an arbitrary length L is selected from a plurality of (for example, seven) spacers 25 having different lengths L, and the spacers 25 thus mounted are used. When the length (the length from the portion that contacts the faucet body 7 to the portion that contacts the holder 19) is changed or the spacer 25 is attached or detached, the connector 24 is inserted into the holder 19. The distance from the portion to be inserted into the faucet body 7 is changed, and the position of the faucet body 7 moves in the front and back direction of the wall W (the distance from the wall W to the faucet body 7 is also changed). become.

  As the spacer 25, a spacer having a length L corresponding to the pattern of the thickness of the wall W may be prepared. In this embodiment, the length L is in a range of 3.2 mm to 18.2 mm (7 types (3 2 mm, 6.2 mm, 9.2 mm, 11.2 mm, 14.2 mm, 15.2 mm, 18.2 mm). 3A and 3B show a case where a spacer 25 having a length L of 18.2 mm is used on a wall W having a thickness of 9.5 mm, and FIGS. ) Shows a case where a spacer 25 having a length L of 3.2 mm is used on a wall W having a thickness of 25 mm.

  As described above, the holder 19, the connector 24, and the spacer 25 are used to fix the spacer M to the stud M, and to the faucet body 7 disposed on the back side of the wall W, it is attached to the opening 8 of the faucet body 7. The front portion of the valve 9 protrudes to the front side of the wall W through a water faucet mounting hole Wa having a size of, for example, 100 mm long × 50 mm wide, provided on the wall W and positioned on the front side of the holder 19. . And the cover 4 which covers the attachment hole Wa with respect to the to-be-latched groove 9a (refer FIG. 3 (A) and (B), FIG. 5 (A) and (B)) provided in the front part of this valve | bulb 9 is provided. The cover 4 is fixed on the front side of the wall W when the locking claws 4a (see FIGS. 3A and 3B and FIG. 6) provided on the upper side are locked. After the cover 4 is fixed, the flow rate adjusting member 3 is attached to the front portion of the valve 9 protruding from the upper opening 4b of the cover 4 to the front side of the wall W (see FIG. 4).

  On the other hand, as shown in FIGS. 10A to 10D, the joint portion 2 protruding from the lower opening 4c (see FIG. 4) of the cover 4 to the front side of the wall W after the cover 4 is fixed is provided. The flange member 5 is attached. As shown in FIGS. 10B and 10C, the flange member 5 of this embodiment is provided with a notch hole 26 from the center portion to the peripheral edge portion, and in the notch hole 26, the center of the flange member 5 is provided. The hole part 26b located in the peripheral part is larger than the hole part 26a located in the part. 10 (A) and 10 (B), after passing the joint portion 2 through the hole portion 26b near the peripheral edge of the flange member 5, the flange member 5 is slid, and FIGS. As shown in D), by moving the joint portion 2 to the inside of the hole portion 26a near the center of the flange member 5, the mounting of the flange member 5 to the joint portion 2 is completed, and the water supply hose H to the joint portion 2 is completed. Can be connected (see FIG. 10E). In FIG. 2, the notch hole 26 is not shown.

  In the embedded water faucet of this embodiment, even when the interval between the stud M and the wall W and the thickness of the wall W vary depending on the construction site, the length of the spacer 25 is changed to change the wall W of the flow rate adjusting member 3. The amount of protrusion (protrusion amount) to the front side can be made uniform, whereby the state of the embedded faucet after installation can be easily improved and the length of the spacer 25 is changed ( Since it is only necessary to select a spacer 25 having an appropriate length), the workability can be improved. In addition, in the embedded faucet of this embodiment, since both the flow rate adjusting member 3 and the cover 4 are fixed (attached) to the valve 9, the distance from the cover 4 to the flow rate adjusting member 3 is independent of the thickness of the wall W. This inevitably becomes constant, and this also makes it possible to easily perform a good installation of the embedded faucet.

  Further, the spacer 25 is a small one having a length L of about 3.2 mm to 18.2 mm, and can be made using an inexpensive synthetic resin such as POM. The present embodiment using the spacer 25 is more advantageous in terms of reducing the manufacturing cost than the case of using the large frame-like spacer used in the above. Moreover, since the spacer 25 is small, even if it is many types of spacers 25, it can be conveyed compactly by packing appropriately.

  Furthermore, since the embedded water faucet of this embodiment can eliminate the housing used in the conventional embedded water faucet, this point also contributes to cost reduction and is excellent in terms of downsizing the installation space.

  In addition, since the pipe connection member 10 to which the water supply pipe is connected is rotatable with respect to the faucet body 7, not only when such a water supply pipe is piped from under the floor but also when it is piped from the ceiling, for example. Is also available.

  In addition, this invention is not limited to said embodiment at all, Of course, it can change and implement variously in the range which does not deviate from the summary of this invention. For example, the following modifications can be given.

  The water supply target T is not limited to a washing machine, and may be other devices such as a water purifier, a dishwasher, and a water heater.

  In order to enable easy installation of the cover 4 and thus the embedded faucet 1 regardless of the thickness of the wall W, the cover 4 is directly attached to the holder 19 fixedly arranged on the back side of the wall W. Instead, the cover 4 may be held by being locked or fixed to the faucet body 7 whose position is adjusted by the spacer 25 or a member (for example, the valve 9 or the joint portion 2) connected to the faucet body 7. That's fine. Therefore, in the above-described embodiment, the cover 4 has a locking groove 9a (see FIGS. 3A and 3B, FIGS. 5A and 5B) provided in the front portion of the valve 9. The cover 4 is held by locking the locking claw 4a (see FIGS. 3A and 3B and FIG. 6), but the method of holding the cover 4 is not limited to this.

  The holder 19 can be attached not only to the stud M but also to a tree that extends in a substantially horizontal direction. In this case, the second attachment surface part, not the first attachment surface part 20, is used to attach the holder 19 to the tree. 21 (see FIG. 4) may be used.

  The connecting tool 24 is not limited to a screw with a built-in washer, but may be a normal type screw without a built-in washer, for example, a bolt and a nut. In this case, the holding tool 19, the spacer 25, and the faucet body 7 What is necessary is just to screw a nut in the front-end | tip part of the volt | bolt which penetrated the (female screw part 7a) and protruded the outer side of the faucet main body 7. FIG.

  As a method of changing the length of the spacer 25, in addition to the above-described method of selecting and removing the spacer 25 having an arbitrary length from the plurality of spacers 25 having different lengths, for example, a spacer formed longer A method of cutting 25 to an arbitrary length, and a method of using a plurality of spacers having the same length or different from each other in appropriate combination.

  The configuration is not limited to the configuration in which the holding surface portion 22, the spacer 25, and the female screw portion 7a are arranged in this order from the front side. For example, the holding surface portion 22, the spacer 25, and the female screw portion 7a may be arranged in this order from the rear side. That is, in the above embodiment, the connection tool 24 is inserted into a portion of the faucet body 7 that is located farther from the holding surface portion 22 with respect to the wall W, but is retained with respect to the wall W in the faucet body 7. You may make it insert in the part located near the surface part 22. FIG.

  Moreover, you may make it insert the connection tool 24 not from the front side but from the rear side with respect to the holding surface part 22, the spacer 25, and the internal thread part 7a. The female screw portion 7a (the portion into which the connector 24 is inserted in the faucet body 7) is not limited to the one provided on the left side of the faucet body 7 when viewed from the outside of the wall W.

  Next, an embedded faucet 31 according to a second embodiment of the present invention will be described with reference to FIGS.

In addition, bead processing is applied to the bent portion serving as the boundary between the first mounting surface portion 48 and the second mounting surface portion 49 and the bent portion serving as the boundary between the first mounting surface portion 48 and the holding surface portion 50. .

  Each of the first and second mounting surface portions 48 and 49 is provided with, for example, a plurality of (two in the illustrated example) long holes 48a and 49a for screwing with the screws 23, and the holding surface portion 50 includes a connector. For example, a plurality (two in the illustrated example) of female screw portions 50a inserted through the screw 24 are provided. Further, a positioning protruding portion 51 that protrudes to the front side of the holding surface portion 50 is provided at the front portion of each of the first and second mounting surface portions 48 and 49.

  The connection tool 24 is inserted (screwed) over the insertion hole 35 b (see FIG. 14) provided in the faucet body 35 and the female thread portion 50 a of the holding surface portion 50 of the holder 47 so as to connect both 35 and 47. It is configured. In addition, although the connection tool 24 of this form is also a washer built-in screw (so-called Sems screw), in FIG. 14, illustration of the washer of the connection tool 24 is omitted.

  Further, as shown in FIG. 14, the spacer 25 is mounted so as to be inserted into a portion between the portion inserted into the faucet body 35 and the portion inserted into the holding tool 47 in the connection tool 24. The spacer 25 is detachable, and can be either attached as shown in FIG. 16B or removed as shown in FIG.

  Here, in this embodiment, a spacer 25 having an arbitrary length L is selected from a plurality of types (for example, four types) of spacers 25 having different lengths L, and the spacers 25 thus mounted are used. By changing the length (the length from the portion that contacts the holder 47 to the portion that contacts the faucet body 35) or by attaching or detaching the spacer 25, The distance from the inserted part to the part inserted into the faucet body 35 is changed, and the position of the faucet body 35 moves in the front and back direction of the wall W (the distance from the wall W to the faucet body 35 is also changed). It will be.

  In this embodiment, a plurality of spacers 25 having the same length or different from each other are used in appropriate combination, and four types (3.0 mm, 4 mm) in which the length L ranges from 3.0 mm to 9.5 mm. (.0 mm, 7.0 mm, 9.5 mm) spacers 25 are prepared. That is, in this embodiment, when the thickness of the wall W is 9.5 mm (see FIGS. 15A and 17), the spacer 25 is not attached to the connection tool 24 as shown in FIG. When the thickness of the wall W is 12.5 mm (see FIG. 15B), only one spacer 25 having a length L of 3.0 mm is attached to the connector 24 (see FIG. 16B). For example, when the thickness of the wall W is 25 mm, two spacers 25 having a length L of 3.0 mm and one spacer 25 having a length L of 9.5 mm are combined and attached to the connector 24. To do.

  In addition, the holder 19 of the first embodiment is installed such that the front surface of the holding surface portion 22 is along the front surface of the stud M (or the back surface of the wall W), and the rear side of the holding surface portion 22 (the side far from the wall W). ) Is connected to the faucet body 7, but in the holder 47 of the second embodiment, the front edge of the projecting portion 51 provided at the front part of the first and second mounting surface parts 48, 49 is the spacer M. Since the faucet body 35 is connected to the front side (side closer to the wall W) of the holding surface portion 50, the holding surface portion 50 is more than the front edge of the protruding portion 51. Is also configured to be far from the wall W by a predetermined interval.

  As described above, the holding tool 47 and the connecting tool 24 are used, and if necessary, the faucet body 35 fixed to the stud M using the spacer 25 is attached to the opening 36 of the faucet body 35. The front portion of the valve 37 protrudes to the front side of the wall W through a faucet mounting hole Wa having a size of, for example, 100 mm long × 50 mm wide provided on the wall W (see FIG. 14). In this embodiment, the cover 34 is attached to the faucet body 35 by two fixing screws 52 (see FIG. 14) inserted through two insertion holes 34a (see FIG. 18) provided in the cover 34. The cover 34 is fixed on the front side of the wall W. A cap 53 (see FIG. 14) is detachably attached to the cover 34 so as to cover the two fixing screws 52.

  Then, after fixing the cover 34, the inner serration 46b of the flow rate adjusting member 33 with respect to the outer serration 46a of the valve 37 provided on the cover 34 and projecting to the front side of the wall W from the cylindrical portion 34b facing obliquely downward. And the flow rate adjusting member 33 is held by the cover 34. That is, an O-ring 33a (see FIG. 15A) is attached to the rear portion of the flow rate adjusting member 33, and the O-ring 33 has a plurality of (e.g., eight) claws provided on the cylindrical portion 34b of the cover 34. 34c (see FIGS. 14 and 18). The plurality of claws 34c are not all on the same circumference, but as shown in FIG. 18, the claws 34c shifted to the front side and the claws 34c shifted to the rear side are alternately arranged in the circumferential direction. The O-ring 33a can be held between the plurality of claws 34c located on the front side and the plurality of claws 34c located on the rear side.

  As described above, the flow rate adjusting member 33 is configured to be serrated and fitted to the valve body 39 while being held by the cover 34. Therefore, when the flow rate adjusting member 33 is rotated, Although it moves in the axial direction together with the portion 32, the flow rate adjusting member 33 only rotates and does not move, so that the operability of the flow rate adjusting member 33 is excellent.

  After the flow rate adjusting member 33 is held by the cover 34 as described above, the flange member 5 is attached to the joint portion 32 protruding from the cylindrical portion 34b (see FIG. 14) of the cover 34 to the front side of the wall W. Thus, the water supply hose H can be connected to the joint portion 32. In addition, the mounting method of the flange member 5 with respect to the joint part 32 is performed similarly to the mounting method of the flange member 5 with respect to the joint part 2 of 1st Embodiment (refer FIG. 10 (A)-(D)). In FIG. 12, the illustration of the cutout hole 26 is omitted as in FIG.

  In the second embodiment configured as described above, in addition to the effects obtained in the first embodiment, the joint portion 32 exposed to the front side of the cover 34 and the flow rate adjustment member 33 are integrated. The effect that the cover 34 can be reduced in size is obtained.

  In the second embodiment, since the flow rate adjusting member 33 is held by the cover 34, the interference between the flow rate adjusting member 33 and the cover 34 can be easily and reliably prevented.

  For example, the holder 47 shown in FIG. 19 may be deformed so as to have a shape without the second attachment surface portion 49 as shown in FIGS.

  In the first and second embodiments, the holders 19 and 47 are attached to the stud M on the left side of the mounting hole Wa when viewed from the outside of the wall W, but the stud M is on the opposite side (right side). In some cases, the holders 19 and 47 may be attached. For this purpose, for example, a portion (internal thread portion 7a, insertion hole 35b) into which the connector 24 is inserted in the faucet body 7, 35 is provided on the right side (or on both the left and right sides) of the faucet body 7, 35. In this case, since the holders 19 and 47 cannot be used in the orientation shown in FIGS. 4 and 14, the holders 19 and 47 are turned upside down with the holding surface portions 22 and 50 facing forward. It is sufficient to use it in such a state.

  In addition, the part (internal thread part 7a, insertion hole 35b) in which the connection tool 24 is inserted in the faucet bodies 7 and 35 is not limited to the left and right sides of the faucet bodies 7 and 35, and may be provided on the upper side, for example.

  Here, as shown in FIGS. 21A and 21B, the following effects can be obtained by providing a portion (female screw portion 35c) into which the connector 24 is inserted not only on the left side of the faucet body 35 but also on the upper side. It is done. That is, even when the holder 47 without the second mounting surface portion 49 as shown in FIGS. 20A to 20G is used, the first mounting surface portion 48 is directed upward with the holding surface portion 50 facing the front side. Thus, it becomes possible to attach the faucet body 35 to the lower surface of the tree extending substantially horizontally using the holder 47 shown in FIGS. 20 (A) to (G). When using the holder 47 shown in FIGS. 19 (A) to 19 (G), the second holding surface portion 49 is directed to the right side with the holding surface portion 50 facing the front side. It becomes possible to attach the faucet body 35 to the right column M using the holder 47 shown in A) to (G). Such a modification can be similarly performed for the faucet body 7 and the holder 19 of the first embodiment.

  Moreover, the holder which has the shape (shape which reversed right and left) used as the mirror image of the holder 47 shown to FIG. 19 (A)-(G) or FIG. 20 (A)-(G) can also be used. In that case, a portion (insertion hole 35b) into which the connection tool 24 is inserted may be provided on the right side instead of the left side of the faucet body 35. Such a modification can be similarly performed for the faucet body 7 and the holder 19 of the first embodiment.

  The insertion hole 22a of the first embodiment may be a female screw portion into which the connection tool 24 is screwed. Further, the insertion hole 35b of the second embodiment may be a female screw portion into which the connection tool 24 is screwed.

  Needless to say, the configurations of the above-described embodiments and modifications thereof may be appropriately combined.
