[0019] <A. First Embodiment> Hereinafter, a first embodiment of an attachment attached to a hot water supply faucet according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of the hot water supply faucet according to this embodiment, and FIG. 2 is a side view showing a state in which the attachment is attached to the hot water supply faucet of FIG. 1. Hereinafter, first, the hot water supply faucet 10 will be described, and then the attachment 20 attached thereto will be described. For convenience of explanation, the description will be made based on the direction shown in FIG. 1. Also, the direction perpendicular to the plane of FIG. 1 will be described as the left-right direction. And the description of other drawings will also be made according to this direction. However, this direction is a regulation for explaining this embodiment, and the present invention is not limited to this direction.

[0020] <1. Hot water supply faucet> The hot water supply faucet 10 according to this embodiment is used, for example, in a store such as a conveyor belt sushi restaurant, and is connected to a hot water supply branch pipe 30 branched from a pipe (not shown) through which hot water in the store flows. As shown in FIG. 1, this hot water supply faucet 10 extends in the front-rear direction and includes a tubular faucet body 1 connected to the hot water supply branch pipe 30, an opening / closing mechanism attached to the front end side of the faucet body 1, and a nozzle portion 2 extending upward from near the center in the front-rear direction of the faucet body 1.

[0021] The faucet body 1 is formed in a cylindrical shape, and a male thread 11 for connecting to the hot water supply branch pipe 30 is formed at the rear end portion. And hot water is supplied from the hot water supply branch pipe 30 to the faucet body 1. The opening / closing mechanism includes a valve member (not shown) housed inside the faucet body 1 and a push button 3 for opening and closing this valve member. The valve member is disposed in the faucet body 1 at the portion where the nozzle portion 2 is attached. When the valve member is in the closed state, the supply of hot water from the faucet body 1 to the nozzle portion 2 side is restricted, and when it is in the open state, hot water flows from the faucet body 1 to the nozzle portion 2 side.

[0022] The push button 3 is attached to the front end of the faucet body 1. More specifically, this push button 3 is attached so that it can move a predetermined length in the front-rear direction by a stopper (not shown). Further, this push button 3 is constantly biased forward by a spring (not shown). When the push button 3 is pushed backward against this spring, the valve member is opened, and hot water flows from the faucet body 1 to the nozzle portion 2 side. Further, a female thread 31 for attaching the attachment 20, which will be described later, is formed on the front surface of the push button 3. The portion constituting the foremost part of the push button 3 on which this female thread 31 is formed is formed in a disc shape.

[0023] The nozzle portion 2 is a member for discharging the hot water flowing from the faucet body 1, and includes a tubular first portion 21 extending upward from the faucet body 1 and a tubular second portion 22 extending forward from the upper end of the first portion 21, and is formed in a substantially L shape in side view. However, the connecting portion between the first portion 21 and the second portion 22 is formed in a smooth curved shape in side view.

[0024] A cylindrical discharge port 23 protrudes slightly downward on the lower surface of the tip of the second portion 22, and hot water is discharged from this discharge port 23. Further, by providing the first portion 21 and the second portion 22, the discharge port 23 is configured to be located above and in front of the push button 3.

[0025] When the push button 3 is pushed backward, the valve member is opened, hot water flows from the faucet body 1 into the nozzle portion 2, and hot water flows downward from the discharge port 23.

[0026] <2. Attachment> Next, the attachment according to the present embodiment will be described with reference to FIGS. 3 to 5. FIG. 3 is a perspective view of the attachment seen from the front, FIG. 4 is a perspective view of the attachment seen from the rear, FIG. 5A is a perspective view of the washer provided on the attachment seen from the front, and FIG. 5B is the washer provided on the attachment Cross-sectional view of is.

[0027] As shown in FIG. 2, this attachment 20 includes an attachment body 4 formed from a plate material, a socket screw 6 for fixing the attachment body 4 to the hot water faucet 10, and a washer 5 disposed between the attachment body 4 and the push button 3.

[0028] As shown in FIGS. 3 and 4, the attachment body 4 includes a main body portion 41, a fulcrum portion 42 connected to the upper end of the main body portion 41, and a support portion 43 connected to the lower end of the main body portion 41, and these are integrally formed.

[0029] The main body portion 41 is formed of a plate material having a rectangular shape in front view, and a rectangular first through hole 411 is formed near the center in the vertical direction. A protruding portion 412 extending downward is connected to the upper edge of the first through hole 411. The protruding portion 412 includes a rectangular upper portion 413 connected to the upper edge of the first through hole 411 and a lower portion 414 connected to the lower end of the upper portion 413. The upper portion 413 extends obliquely downward from the upper edge of the first through hole 411 toward the front, and the lower portion 414 extends obliquely downward from the lower end of the upper portion 413 toward the rear. Therefore, the protruding portion 412 having the upper portion 413 and the lower portion 414 is formed to protrude forward in a mountain shape in side view.

[0030] A circular second through hole 415 is formed above the protruding portion 412, and the above-described socket screw 6 is inserted into the second through hole 415. Therefore, the inner diameter of the second through hole 415 is smaller than the outer diameter of the head of the socket screw 6.

[0031] The fulcrum portion 42 includes a rectangular first portion 421 extending upward from the upper end of the main body portion 41, and a second portion 422 extending forward from the upper end of the first portion 421. The first portion 421 is formed in a plate shape that is slightly narrower than the main body portion 41 and extends obliquely backward from the main body portion 41. The second portion 422 is formed in a plate shape, and an arc-shaped recess 423 is formed at the front end. This recess 423 is adapted to engage with the outer peripheral surface of the discharge port 23 provided in the nozzle portion 2 from the rear.

[0032] The support portion 43 includes a stepped portion 431 extending forward from the lower end of the main body portion 41, an extending portion 432 extending downward from the front end of the stepped portion 431, a bottom wall portion 433 extending forward from the lower end of the extending portion 432, and a pair of clamping portions 434 extending forward from both side edges of the extending portion 432, and these are integrally formed.

[0033] The extending portion 432 and the bottom wall portion 433 are connected in an L shape in a side view. As will be described later, when supplying hot water, the bottom 61 of the drinking cup 6 is placed on the bottom wall portion 433, and the outer peripheral surface of the drinking cup 6 is pressed against the extending portion 432. The pair of clamping portions 434 are connected obliquely to the extending portion 432 so as to be separated from each other as they extend forward from the extending portion 432. Thereby, when the drinking cup 6 is placed on the bottom wall portion 433, the outer peripheral surface of the drinking cup 6 is clamped by the clamping portions 434.

[0034] The material forming the attachment body 4 is not particularly limited, and for example, it can be formed of metal, resin material, or the like.

[0035] Next, the washer 5 will be described. As described above, the washer 5 is disposed between the attachment body 4 and the push button 3. However, as shown in FIGS. 5A and 5B, on the side of the attachment body 4, a flat surface 51 is formed, and this flat surface 51 is in contact with the rear surface of the main body portion 41 of the attachment body 4. On the other hand, the side in contact with the push button 3 is formed in a mountain shape having a top (protrusion) 52 with an annular cross section. That is, it extends obliquely rearward from the outer edge of the washer 5 toward the top 52 in the radially inward direction, and extends obliquely forward from the top 52 toward the inner edge of the through hole 53 in the radially inward direction. And the top 52 of the washer 5 is in contact with the front surface of the push button 3.

[0036] <3. Attachment Mounting Method> Next, a method of attaching the attachment body 4 to the hot water supply faucet 10 will be described. First, the attachment body 4 is disposed below the nozzle portion 2, and the recess 423 of the fulcrum portion 42 is engaged with the outer peripheral surface of the discharge port 23 from the rear side. Next, with the washer 5 disposed between the attachment body 4 and the push button 3, the socket head cap screw 6 is inserted through the second through hole 415 from the front, and the male screw of the socket head cap screw 6 is screwed into the female screw 31 on the front surface of the push button 3. At this time, the socket head cap screw 6 is screwed until a part of the flat surface 51 of the washer 5 contacts the rear surface of the attachment body 4 and the top 52 contacts the front surface of the push button 3. Thus, as shown in FIG. 2, the attachment 20 is completely attached. At this time, by adjusting the length of the second portion 422 of the fulcrum portion 42, the angle between the first portion 421 and the second portion 422, the angle between the fulcrum portion 42 and the main body portion 41, etc., the main body portion 41 is arranged to extend obliquely downward with respect to the front surface of the push button 3. Therefore, in the initial state, the rear surface of the main body portion 41 is arranged to contact the upper end portion of the flat surface 51 of the washer 5 (see FIG. 8A).

[0037] <4. Method of Using the Hot Water Supply Faucet> When the attachment 20 is attached to the hot water faucet 10 as described above, hot water is supplied as follows. First, as shown in FIG. 6, while placing the bottom 61 of the hot water cup (container) 6 containing a tea bag or powdered tea on the bottom wall portion 433 of the attachment body 4, the lower end portion of the outer peripheral surface of the hot water cup 6 is pressed against the extending portion 432. Note that it may be sufficient to simply press the lower end portion of the outer peripheral surface of the hot water cup 6 against the extending portion 432. At this time, since the outer peripheral surface of the hot water cup 6 contacts the protruding portion 412, it does not contact the main body portion 41. Further, the outer peripheral surface of the hot water cup 6 is supported from both sides by the pair of clamping portions 434.

[0038] When the hot water cup 6 is pressed against the extending portion 432 in this way, as shown in FIG. 7, the tip of the fulcrum portion 42, that is, the concave portion 423 engaged with the discharge port 23 serves as a fulcrum, and the attachment body 4 rotates backward. In this process, the push button 3 is pushed in by the attachment body 4, and hot water is discharged from the discharge port 23. The discharged hot water accumulates in the hot water cup 6 disposed therebelow. However, when a desired amount of hot water accumulates in the hot water cup 6, the pressing of the extending portion 432 by the hot water cup 6 is released. As a result, the pushing in of the push button 3 is released, and the discharge of hot water from the discharge port 23 stops. Thereafter, the hot water cup 6 is removed from the attachment body 4.

[0039] <5. Features> According to the attachment 20 configured as described above, the following effects can be obtained. (1) In the attachment body 4 according to the present embodiment, with the fulcrum portion 42 as a fulcrum, the vicinity of the lower end of the attachment body 4 below the push button 3, that is, the extending portion 432 is configured to be pressed by the hot water cup 6. At this time, since the push button 3 is pressed near the center in the vertical direction of the attachment body 4, the push button 3 can be pressed with a weaker force compared to directly pressing the push button 3.

[0040] (2) Since the protruding portion 412 is formed on the main body portion 41, it is possible to prevent the outer peripheral surface near the upper opening of the hot water cup 6, that is, the portion where the user puts the mouth, from contacting the main body portion 41. Therefore, it is hygienic.

[0041] (3) When pressing the extension part 432 with the hot water container 6, since the hot water container 6 is clamped from the side by the pair of clamping parts 434, it is possible to suppress the hot water container 6 from shifting in the left - right direction. Therefore, the force for pressing the hot water container 6 can be efficiently applied rearward.

[0042] (4) Since the washer 5 smaller than the outer diameter of the push - button 3 is arranged between the push - button 3 and the attachment body 4, the pushing force can be efficiently transmitted to the push - button 3 via the washer 5. This will be described with reference to FIG. 8.

[0043] As shown in FIG. 8A, in the initial state, the main body part 41 of the attachment body 4 is in oblique contact with the flat surface 51 of the washer 5. That is, the main body part 41 contacts near the upper end of the flat surface 51, and a gap is formed between the lower end of the flat surface 51 and the main body part 41. When the attachment body 4 is pushed in from this state, the main body part 41 contacts near the lower end of the flat surface 51, and a gap is formed between the upper end of the flat surface 51 and the main body part 41. In this way, the main body part 41 and the washer 5 are not in surface contact, but in point contact or line contact so that the contact position changes to accommodate the rotation of the attachment body 4. Therefore, even if the attachment body 4 rotates, the force can be efficiently transmitted.

[0044] Furthermore, the part of the washer 5 in contact with the push - button 3 is the annular top 52, and it is in substantially line contact with the push - button 3. Also, this top 52 has a diameter smaller than the outer diameter of the washer 5. Therefore, the force acting on the washer 5 can be concentrated near the center of the push - button 3, and the force for pushing the hot water container 6 can be efficiently transmitted to the push - button 3. As a result, the force for pressing the push - button 3 can be reduced.

[0045] <6. Modified Example> Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications are possible without departing from the spirit thereof. Note that the following modification examples can be combined as appropriate.

[0046] (1) The structure of the washer 5 is not particularly limited, and a normal washer without a top portion 52, that is, a washer in which both axial surfaces are flat surfaces, may be used. Also, the washer 5 is not necessarily required, and the main body portion 41 can be directly fixed to the push button 3. Also, instead of the countersunk screw 6, other components such as bolts may be used. Also, the position where the countersunk screw 6 or the like is attached is not particularly limited, and it may be other than the push button 3.

[0047] (2) In the above embodiment, the attachment body 4 is installed so as to be slightly inclined with respect to the push button 3, but the attachment body 4 may be installed so that the front surface of the attachment body 4 and the push button 3 are parallel.

[0048] (3) In the above embodiment, the attachment body 4 is integrally formed of a plate material, but it can also be formed by combining a plurality of members.

[0049] (4) Although the support portion 43 is arranged so as to be positioned forward with respect to the main body portion 41, the support portion 43 may be arranged on the extension of the main body portion 41.

[0050] (5) The configuration of the protruding portion 412 is not particularly limited, and it may be configured such that a gap is formed between the attachment body 4 and the beverage cup 6. However, the protruding portion 412 is not necessarily required and may not be provided. Similarly, the clamping portion 434 is not necessarily required.

[0051] (6) A recess 423 is formed in the fulcrum portion 42 of the attachment main body 4 and attached to the outer peripheral surface of the discharge port 23. However, the present invention is not limited to this. As long as it is attached to the nozzle portion 2 above the push button 3 so as to serve as a fulcrum during turning, the attachment position and the attachment method are not particularly limited. Further, the attachment main body 4 may have dimensions such that when it comes into direct or indirect contact with the push button 3, it is attached to any position of the nozzle portion 2 such as the discharge port 23 so that the fulcrum portion 42 serves as a fulcrum.

[0052] (7) For the attachment 20 of the above embodiment, if the socket screw 6 is removed, the attachment main body 4 can be easily removed from the hot water supply faucet 10. For example, when the attachment main body 4 is dirty, it can be removed and cleaned. Also, when the attachment main body 4 is damaged, it can be easily replaced. Further, the hot water supply faucet 10 can be used with the attachment 20 removed.

[0053] <B. Second Embodiment> Next, a second embodiment of the attachment of the present invention will be described with reference to FIGS. 9 to 12. FIG. 9 is a side view showing a state where the attachment is attached to the hot water supply faucet, FIG. 10 is a perspective view of the attachment seen from the front, FIG. 11 is a perspective view of the attachment seen from the rear, and FIG. 12 is a side view for explaining the dimensional relationship between the attachment and the hot water supply faucet. Since the hot water supply faucet is the same as that of the first embodiment, the description thereof is omitted.

[0054] <1. Attachment> As shown in FIGS. 9 to 11, this attachment 70 includes an attachment main body 7 formed of a plate material and a support portion 8 extending from the lower end portion of the attachment main body 7.

[0055] The attachment main body 7 includes a main body portion 71 and a fulcrum portion 72 connected to the upper end of the main body portion 71, and these are integrally formed. Further, on the back surface of the main body portion 71, a first engagement that engages with the upper edge of the push button 3 Part 73. A protruding member 74 is provided below the first engaging portion 73 and can contact the push button 3.

[0056] The main body portion 71 has a first portion 711 formed in a rectangular shape and a second portion 712 integrally connected to the lower end portion of the first portion 711. The width of the second portion 712 is larger than that of the first portion 711. A fulcrum portion 72 is connected to the first portion 711 as will be described later. Both sides of the second portion 712 have their upper and lower end portions bent backward in a U shape, and insertion portions 713 through which a support portion 8 to be described later is inserted are respectively formed. Also, at both sides of the second portion 712, the portion between the vertically arranged insertion portions 713 is bent backward in a U shape, and a second engaging portion 714 that engages with the outer edge of the push button 3 is formed. Each second engaging portion 714 protrudes rearward from the insertion portion 713.

[0057] A rectangular notch 715 is formed at the lower end of the main body portion 71, and a protruding portion 716 extending downward is connected to the upper edge of the notch 715. This protruding portion 716 has the same function as the protruding portion 412 of the first embodiment. That is, this protruding portion 716 includes a rectangular upper portion 717 connected to the upper edge of the notch 715 and a lower portion 718 connected to the lower end of the upper portion 717. The upper portion 717 extends obliquely downward forward from the upper edge of the notch 715, and the lower portion 718 extends obliquely downward rearward from the lower end of the upper portion 717. Therefore, the protruding portion 716 having the upper portion 717 and the lower portion 718 is formed to protrude forward in a mountain shape in a side view.

[0058] As shown in FIG. 11, the first engaging portion 73 has a plate-shaped first part 731 fixed to the back surface of the main body portion 71 with an adhesive or the like, and a plate-shaped second part 732 extending downward from the upper end of the first part 731. The second part 732 extends obliquely downward from the upper end of the first part 731 toward the rear, and a gap is formed between the second part 732 and the first part 731. Further, the first part 731 and the second part 732 are connected so as to be elastically deformable, and when a force is applied forward to the second part 732, the second part 732 comes closer to the first part 731.

[0059] The protruding member 74 is a columnar rod-shaped member extending in the horizontal direction and is fixed with an adhesive or the like between the first engaging portion 73 and the protrusion 716 on the back surface of the main body portion 71.

[0060] The fulcrum portion 72 is formed so as to extend forward from the upper end portion of the main body portion 71 so as to be orthogonal to the main body portion 71. The fulcrum portion 72 is formed in a plate shape, and an arcuate concave portion 721 is formed at the front end portion. This concave portion 721 is adapted to engage with the outer peripheral surface of the discharge port 23 provided in the nozzle portion 2 from the rear.

[0061] Next, the support portion 8 will be described. The support portion 8 is a member formed by bending a wire rod, and supports the vicinity of the lower end of the hot water cup 6 as will be described later. The support portion 8 is composed of a pair of first portions 81, a pair of second portions 82, and a third portion 83. The first portion 81 is a linear portion that constitutes both ends of the support portion 8, and is inserted into the insertion portion 713 described above and extends downward. At the upper end of the first portion 81, a retaining portion 811 with a large outer shape is provided, which prevents the support portion 8 from detaching downward from the insertion portion 713. At the lower end of each first portion 81, a second portion 82 is provided respectively. Each second portion 82 extends obliquely forward from the first portion 81 and close to each other, and then extends linearly downward therefrom. And the third portion 83 is provided so as to connect the lower end portions of both second portions 82. The third portion 83 is formed in an elliptical shape that is long in the horizontal direction, and is formed in an arc shape in plan view so that both ends thereof protrude forward. In this way, since the third portion 83 is formed in an arc shape, it can come into contact with the outer peripheral surface of the hot water cup 6.

[0062] As described above, since the first portion 81 is inserted into the insertion portion 713, the support portion 8 can move up and down with respect to the main body portion 71. Thereby, the position of the support portion 8 can be adjusted according to the vertical length of the hot water cup 6.

[0063] Also, as shown in FIG. 12, in the present embodiment, the dimensional relationship between the hot water supply faucet 10 and the attachment 70 is set as follows. As shown in the figure, the horizontal distance D1 between the front surface of the push button 3 of the hot water supply faucet 10 and the rear end portion of the discharge port 23 is shorter than the horizontal distance D2 between the rear end of the protruding member 74 and the rear end of the concave portion 721 of the fulcrum portion 72 when the main body portion 71 of the attachment 70 is arranged to extend in the vertical direction. Thereby, as will be described later, the attachment 70 can be attached to the hot water supply faucet 10 by utilizing the biasing force of the push button 3 and the first engaging portion 73.

[0064] <2. Attachment mounting method> Next, with reference to FIGS. 13 and 14, the method of attaching the attachment 70 to the hot water faucet 10 will be described. First, press the protruding member 74 and the first engaging portion 73 of the attachment 70 against the front surface of the push button 3, and while pressing the push button 3, engage the second engaging portion 714 with the outer edge of the push button 3 from below. At this time, since the first engaging portion 73 is being pushed in, the second portion 732 approaches the first portion 731 due to elastic deformation. In this state, as shown in FIG. 13, while sliding the attachment 70 upward, engage the concave portion 721 of the fulcrum portion 72 with the rear end of the discharge port 23 of the hot water faucet 10. In this process, when the first engaging portion 73 moves above the push button 3, as shown in FIG. 14, the pushing of the second portion 732 is released, so the second portion 732 returns to its original state. As a result, the second portion 732 engages with the upper edge of the push button 3. At this time, the protruding member 74 is disposed at a position where it can contact the front surface of the push button 3.

[0065] Then, when the pushing of the push button 3 is released, as shown in FIG. 12, the distance D1 is shorter than the distance D2, and since the first engaging portion 73 engages with the upper edge of the push button 3, this serves as a retaining means to prevent the attachment 70 from detaching downward. Also, since the second engaging portion 714 engages with both sides of the outer edge of the push button 3, the attachment 70 is prevented from shifting horizontally with respect to the push button 3. Thus, the attachment of the attachment 70 is completed.

[0066] <3. Method of Using the Hot Water Faucet> When the attachment 70 is attached to the hot water faucet 10 as described above, hot water supply is performed as follows. First, as shown in FIG. 15, while bringing the hot water cup 6 containing tea bags or powdered tea into contact with the protruding portion 716 of the attachment 70 and the vicinity of the third portion 83 of the support portion 8, press the lower end portion of the hot water cup 6 against the third portion 83.

[0067] As a result, as shown in FIG. 16, the tip of the fulcrum portion 72, that is, the concave portion 721 engaged with the discharge port 23 serves as a fulcrum, and the attachment 70 pivots backward. In this process, the push button 3 is pushed in by the attachment 70, and hot water is discharged from the discharge port 23. The discharged hot water accumulates in the hot water cup 6 disposed therebelow. However, when a desired amount of hot water accumulates in the hot water cup 6, the pressing of the support portion 8 by the hot water cup 6 is released. As a result, the pushing in of the push button 3 is released, and the discharge of hot water from the discharge port 23 stops. Thereafter, the hot water cup 6 is removed from the attachment 70.

[0068] <4. Features> According to the attachment 70 configured as described above, in addition to the effects obtained by the attachment of the first embodiment, the following effects can be obtained.

[0069] (1) Since the attachment 70 can be attached to the hot water faucet 10 while being slid, it is not necessary to use tools, and the attachment is easy.

[0070] (2) The protruding member 74 can obtain the same effect as the washer of the attachment of the first embodiment. That is, since the protruding member 74 is formed in a rod shape, the force pressing the attachment 70 via the hot water cup 6 can be concentratedly applied to the push button 3. Further, since the protruding member 74 is formed in a columnar shape extending in the horizontal direction, the curved surface of its outer peripheral surface contacts the push button 3. Therefore, even when the attachment 70 contacts the push button 3 while tilting, the outer peripheral surface of the protruding member 74 always makes line contact with the push button 3, so that the force can be efficiently transmitted to the push button 3.

[0071] (3) Since the position of the support portion 8 can be adjusted with respect to the main body portion 71, the position of the support portion 8 can be changed according to the height of the hot water cup 6.

[0072] <5. Modification Example> The above describes the embodiments of the present invention. However, the present invention is not limited thereto, and various modifications are possible without departing from the spirit thereof. Note that the following modification examples can be combined as appropriate.

[0073] (1) In the above-described second embodiment, the support portion 8 is provided movably with respect to the attachment main body 7, but the support portion 8 may be fixed to the attachment main body 7. The shape of the support portion 8 is not particularly limited, and it can also be formed of a plate material instead of a wire material.

[0074] (2) The configurations of the first engaging portion 73 and the second engaging portion 714 are not particularly limited as long as they are configured to engage with the push button 3. Therefore, it can be appropriately changed according to the shape of the push button.

[0075] (3) The protruding member 74 may have a shape other than the rod shape as described above, and may be a member that contacts the push button 3 with a small area, for example, a member that makes point contact or line contact. However, the protruding member 74 is not essential and may be provided as necessary. When the protruding member 74 is not provided, in the dimensional relationship shown in FIG. 12, the distance D2 is the distance from the portion where the push button 3 contacts the attachment 70 to the rear end portion of the concave portion 721 of the fulcrum portion 72. Also, the protruding portion 716 is not essential and may be provided as necessary.

[0076] (4) In each of the above embodiments, an example of applying the attachment 7 0 according to the present invention to the hot water supply faucet for a revolving sushi has been described. However, the present invention is not limited thereto, and it can be applied to various hot water supply faucets. However, the hot water supply faucet to which the attachment according to the present invention is attached only needs to have at least a nozzle portion 2 having a discharge port 23 that opens downward and a push button 3 disposed below the discharge port 23 and behind the discharge port 23 in the horizontal direction. Other configurations are not particularly limited.
