In addition, the direction perpendicular to the paper surface of Figure 1 will be explained as the left-right direction. Also, regarding other drawings, the explanation will be made in accordance with the setting of the direction. However, the setting of the direction is a provision made for explaining the present embodiment, and the present application is not limited to such a provision of the direction.

[0045] <1. Hot-water supply faucet>

[0046] The hot-water supply faucet 10 regarding the present embodiment is used, for example, in a restaurant serving revolving sushi or the like, and is connected to a hot-water supply branch pipe 30 branched from a pipe (omitted from the drawing) through which hot water flows in the restaurant. As shown in Figure 1The hot water supply faucet 10 shown includes a faucet main body 1 extending in the front-rear direction and connected to a hot water supply branch pipe 30, an opening and closing mechanism installed at the front end side of the faucet main body 1, and a spout 2 extending upward from the vicinity of the center of the front-rear direction of the faucet main body 1.

[0047] The faucet main body 1 is formed in a cylindrical shape, and a male screw 11 for connecting to the hot water supply branch pipe 30 is formed at the rear end portion. Moreover, hot water can be supplied from the hot water supply branch pipe 30 to the faucet main body 1. The opening and closing mechanism includes a valve member (not shown) housed inside the faucet main body 1, and a push button 3 for opening and closing the valve member. The valve member is disposed in the portion of the faucet main body 1 where the spout 2 is to be installed, and when the valve member is in the closed state, the hot water is restricted from being supplied from the faucet main body 1 to the spout 2 side, and when the valve member is in the open state, the hot water can flow from the faucet main body 1 to the spout 2 side.

[0048] The push button 3 is installed at the front end portion of the faucet main body 1. If described in more detail, the push button 3 is installed so as to be able to move only a predetermined length in the front-rear direction by a stopper (not shown). In addition, the push button 3 is normally urged in the front direction by a spring (not shown). Moreover, if the push button 3 is pressed in the rear direction against the spring, the valve member is in the open state, and the hot water can flow from the faucet main body 1 to the spout 2 side. In addition, a female screw 31 for installing a fitting 20 is formed on the front surface of the push button 3, as described later. The portion of the push button 3 that forms the frontmost portion where the female screw 31 is formed is formed in a circular plate shape.

[0049] The spout 2 is a member for discharging hot water flowing from the faucet main body 1, and includes a tubular first portion 21 extending upward from the faucet main body 1, and a tubular second portion 22 extending forward from the upper end of the first portion 21, and is formed in an approximately L shape in side view. However, the connecting portion of the first portion 21 and the second portion 22 is formed in a smooth curved shape in side view.

[0050] A cylindrical discharge port 23 slightly protrudes downward at the lower surface of the front end portion of the second portion 22, and the hot water can be discharged from the discharge port 23. In addition, the first portion 21 and the second portion 22 are provided so that the discharge port 23 is positioned more upward and forward than the push button 3.

[0051] Moreover, if the push button 3 is pressed in the rear direction, the valve member is in the open state, and the hot water flows from the faucet main body 1 into the spout 2, and thus the hot water can flow downward from the discharge port 23.

[0052] <2. Fitting>

[0053] Next, the fitting according to the present embodiment will be described with reference to the drawings. Figure 3 ~5 Figure 1 will be described. Figure 3 is a perspective view of the fitting as viewed from the front, Figure 4 is a perspective view of the fitting as viewed from the rear, Figure 5A is a perspective view of the gasket to be provided on the fitting as viewed from the front, Figure 5B is a sectional view of the gasket to be provided on the fitting.

[0054] As shown in Figure 2 , the fitting 20 is provided with a fitting main body 4 formed of a plate material, a flat head screw 6 for fixing the fitting main body 4 to the hot water supply faucet 10, and a gasket 5 disposed between the fitting main body 4 and the push button 3.

[0055] As shown in Figure 3 and Figure 4 , the fitting main body 4 is provided with a main body portion 41, a fulcrum portion 42 coupled to the upper end of the main body portion 41, and a support portion 43 coupled to the lower end of the main body portion 41, and these members are formed in one piece.

[0056] The main body portion 41 is formed of a plate material having a rectangular shape as viewed from the front, and a rectangular first through-hole 411 is formed near the center in the vertical direction. A protruding portion 412 extending downward is coupled to the upper edge of the first through-hole 411. The protruding portion 412 is provided with a rectangular upper portion 413 coupled to the upper edge of the first through-hole 411, and a lower portion 414 coupled to the lower end of the upper portion 413. The upper portion 413 extends downward obliquely toward the front from the upper edge of the first through-hole 411, and the lower portion 414 extends downward obliquely toward the rear from the lower end of the upper portion 413. Thus, the protruding portion 412 having the upper portion 413 and the lower portion 414 is formed so as to protrude toward the front in a chevron shape as viewed from the side.

[0057] A circular second through-hole 415 is formed above the protruding portion 412, and the flat head screw 6 described above is inserted through the second through-hole 415. Thus, the inner diameter of the second through-hole 415 is smaller than the outer diameter of the head of the flat head screw 6.

[0058] The fulcrum portion 42 is provided with 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 having a width slightly narrower than that of the main body portion 41, and extends slightly obliquely toward the rear from the main body portion 41. The second portion 422 is formed in a plate shape, and a circular arc-shaped recessed portion 423 is formed at the front end portion. The recessed portion 423 is engaged from the rear to the outer peripheral surface of the discharge port 23 provided at the nozzle portion 2.

[0059] The support portion 43 has a stepped portion 431 extending forward from the lower end of the main body portion 41, an extension 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 extension portion 432, and a pair of clamping portions 434 extending forward from both side edges of the extension portion 432, and these components are formed as one body.

[0060] The extension portion 432 and the bottom wall portion 433 are joined so as to have an L shape in side view, and as will be described later, when hot water is supplied, the bottom portion 61 of the tea cup 6 is placed on the bottom wall portion 433, and the outer peripheral surface of the tea cup 6 pushes against the extension portion 432. The pair of clamping portions 434 are joined obliquely with respect to the extension portion 432 in such a manner as to move apart from each other forward from the extension portion 432. Thus, when the tea cup 6 is placed on the bottom wall portion 433, the outer peripheral portion of the tea cup 6 can be clamped by the clamping portions 434.

[0061] The material forming the fitting main body 4 is not particularly limited, and for example, it can be formed of metal, a resin material, or the like.

[0062] Next, the gasket 5 will be described. As described above, the gasket 5 is disposed between the fitting main body 4 and the push button 3, and as shown in Figs. 5 and 6, a flat surface 51 is formed on the fitting main body 4 side, and the flat surface 51 can be joined to the rear surface of the main body portion 41 of the fitting main body 4. On the other hand, the side joined to the push button 3 is formed in a mountain shape having a ring-shaped top portion (projection) 52 in cross section. On the other hand, the gasket 5 is inclined obliquely from the outer edge thereof toward the radially inner side and toward the rear from the top portion 52, and is inclined obliquely from the top portion 52 toward the radially inner side and toward the front from the inner edge of the through hole 53. Further, the top portion 52 of the gasket 5 can be joined to the front surface of the push button 3. Figure 5A and Figure 5B

[0063] <3. Mounting method of fitting>

[0064] Next, the method of mounting the fitting main body 4 on the hot water supply faucet 10 will be described. First, the fitting main body 4 is disposed on the lower side of the spout portion 2, and the recessed portion 423 of the fulcrum portion 42 is engaged to the outer peripheral surface of the discharge port 23 from the rear side. Next, with the gasket 5 disposed between the fitting main body 4 and the push button 3, the flat head screw 6 is inserted through the second through hole 415 from the front side, and the male screw of the flat head screw 6 is screwed into the female screw 31 of the front surface of the push button 3. At this time, a portion of the flat surface 51 of the gasket 5 is joined to the rear surface of the fitting main body 4, and the flat head screw 6 is screwed until the top portion 52 is joined to the front surface of the push button 3. Thus, as shown in Fig. 7, the fitting main body 4 is mounted on the hot water supply faucet 10. Figure 2 ​As shown, the mounting of the fitting 20 is completed. At this time, the length of the second portion 422 of the fulcrum portion 42, the angle of the first portion 421 and the second portion 422, the angle of the fulcrum portion 42 and the main body portion 41, and the like are adjusted, whereby the main body portion 41 can be configured to extend slightly obliquely downward with respect to the front surface of the push button 3. Thus, in the initial state, the rear surface of the main body portion 41 is configured to be engageable with the upper end portion of the flat surface 51 of the gasket 5 (refer to Figure 8A ).

[0065] <4. Method for using a hot water supply faucet>

[0066] As described above, if the fitting 20 is mounted on the hot water supply faucet 10, hot water supply is performed in the following manner. First, as shown in Figure 6 , the lower end portion of the outer periphery surface of the tea cup (vessel) 6, into which a tea bag or tea powder has been put, is pushed against the extension portion 432 while being placed on the bottom wall portion 433 of the fitting main body 4. Alternatively, only the lower end portion of the outer periphery surface of the tea cup 6 can be pushed against the extension portion 432. At this time, the outer periphery surface of the tea cup 6 is engaged with the protrusion portion 412, and thus is not engaged with the main body portion 41. In addition, the outer periphery surface of the tea cup 6 is supported from both sides by the pair of clamping portions 434.

[0067] Thus, if the tea cup 6 is pushed against the extension portion 432, as shown in Figure 7 , the front end of the fulcrum portion 42, that is, the recessed portion 423 engaged with the discharge port 23 becomes a fulcrum, and the fitting main body 4 is rotated rearward. In this process, the push button 3 is pressed into the fitting main body 4, and thus hot water is discharged from the discharge port 23. The discharged hot water is accumulated in the tea cup 6 that has been disposed below the discharge port 23, and if the desired amount of hot water is accumulated in the tea cup 6, the pushing of the extension portion 432 by the tea cup 6 is released. Thus, the pressing of the push button 3 is released, and the discharge of hot water from the discharge port 23 is stopped. Then, the tea cup 6 is detached from the fitting main body 4.

[0068] <5. Features>

[0069] According to the fitting 20 configured as described above, the following effects can be obtained.

[0070] (1) In the fitting main body 4 of the present embodiment, the configuration is such that the lower end portion of the fitting main body 4, that is, the extension portion 432, located below the push button 3, is pushed by a tea cup with the fulcrum portion 42 as a fulcrum. At this time, since the push button 3 is pushed in the vicinity of the center in the vertical direction of the fitting main body 4, the push button 3 can be pushed with a weaker force compared to directly pushing the push button 3.

[0071] (2) Since a protrusion 412 is formed in the main body 41, the outer peripheral surface near the upper opening of the teacup 6, which is the part that will touch the user's mouth, can be prevented from contacting the main body 41. Therefore, it is hygienic.

[0072] (3) When the teacup 6 pushes the extension 432, the teacup 6 is held from the side by a pair of clamping parts 434, so the teacup 6 can be prevented from shifting to the left or right. Therefore, the force of pushing the teacup 6 can be applied to the rearward in an efficient manner.

[0073] (4) Since the washer 5, which is smaller than the outer diameter of the push button 3, is disposed between the push button 3 and the accessory body 4, the pressing force can be efficiently transmitted to the push button 3 through the washer 5. This point will be explained with reference to Figure 8.

[0074] like Figure 8A As shown, in the initial state, the main body 41 of the accessory body 4 is inclined to engage with the flat surface 51 of the washer 5. Furthermore, the main body 41 engages 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 41. From this state, if the accessory body 4 is pressed in, the main body 41 engages 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 41. Therefore, the main body 41 and the washer 5 do not make surface contact but rather make contact through point contact or line contact, allowing for rotation of the accessory body 4. Thus, even if the accessory body 4 rotates, force can be transmitted efficiently.

[0075] Furthermore, the portion of the washer 5 that engages with the push button 3 is an annular top 52, which makes approximately line contact with the push button 3. Additionally, 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 applied to the teacup 6 can be efficiently transmitted to the push button 3. As a result, the force required to push the push button 3 can be reduced.

[0076] <6. Examples of Variation>

[0077] The embodiments of the present invention have been described above; however, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention. Furthermore, the following variations can be appropriately combined.

[0078] (1) The structure of the gasket 5 is not particularly limited, and can be a general gasket without the top portion 52, that is, a gasket having flat surfaces on both sides in the axial direction. In addition, the gasket 5 is not necessarily required, and the main body portion 41 can be directly fixed to the push button 3. In addition, the fixing means can be a fixing means other than the flat head screw 6, and can be a fixing means such as a bolt. In addition, the position where the flat head screw 6 is installed is not particularly limited, and can be a position other than the push button 3.

[0079] (2) In the above embodiment, the accessory main body 4 is arranged so as to be slightly inclined with respect to the push button 3, but the accessory main body 4 can be arranged so as to be parallel to the front surface of the push button 3.

[0080] (3) In the above embodiment, the accessory main body 4 is integrally formed from a plate material, but can be formed by combining a plurality of members.

[0081] (4) The support portion 43 is arranged so as to be located in front of the main body portion 41, but the support portion 43 can be arranged on the extension line of the main body portion 41.

[0082] (5) The structure of the protruding portion 412 is not particularly limited, and can be configured so as to form a gap between the accessory main body 4 and the tea cup 6. However, the protruding portion 412 is not necessarily required, and can not be provided. In addition, the same applies to the gripping portion 434, which is not necessarily required.

[0083] (6) The recess portion 423 is formed in the fulcrum portion 42 of the accessory main body 4, and is installed on the outer peripheral surface of the discharge port 23, but is not limited thereto, and can be installed on the mouth portion 2 so as to be a fulcrum when rotated, without being particularly limited in the installation position and the installation method. In addition, the size of the accessory main body 4 is not particularly limited, and can be installed on any position of the mouth portion 2 such as the discharge port 23 so as to be a fulcrum when directly or indirectly engaged with the push button 3.

[0084] (7) The accessory 20 of the above embodiment can be easily detached from the hot water supply faucet 10 by removing the flat head screw 6, and thus, for example, in the case where the accessory main body 4 is dirty, the accessory main body 4 can be detached and cleaned. In addition, in the case where the accessory main body 4 is damaged, the accessory main body 4 can be easily exchanged. Further, in the state where the accessory 20 is detached, the hot water supply faucet 10 can be used.

[0085] <B. Second Embodiment>

[0086] Next, the second embodiment of the present application will be described with reference to Figures 9-12 Figure 9 ​is a side view showing a state in which the fitting is attached to the hot-water supply faucet, Figure 10 is a perspective view of the fitting as viewed from the front, Figure 11 is a perspective view of the fitting as viewed from the rear, Figure 12 is a side view showing the relationship between the dimensions of the fitting and the hot-water supply faucet. In addition, the hot-water supply faucet is the same as in the first embodiment, so the description thereof is omitted.

[0087] <1. Fitting>

[0088] As shown in Figures 9-11 , the fitting 70 includes a fitting main body 7 formed of a plate material, and a support portion 8 extending from a lower end portion of the fitting main body 7.

[0089] The fitting main body 7 includes a main body portion 71 and a fulcrum portion 72 coupled to an upper end of the main body portion 71, and these components are formed as one body. In addition, on the back surface of the main body portion 71, a first engagement portion 73 that engages with the upper edge of the push button 3, and a protruding member 74 that is disposed below the first engagement portion 73 and can contact the push button 3 are provided.

[0090] The main body portion 71 includes a first portion 711 formed in a rectangular shape, and a second portion 712 integrally connected to a lower end portion of the first portion 711, and the width of the second portion 712 is larger than that of the first portion 711. As will be described later, the fulcrum portion 72 is coupled to the first portion 711. The upper end portion and the lower end portion of both sides of the second portion 712 are bent rearward in a U shape, and insertion portions 713 through which the support portion 8 described later is inserted are formed. In addition, portions between the insertion portions 713 arranged in the up-and-down direction on both sides of the second portion 712 are bent rearward in a U shape, and second engagement portions 714 that engage with the outer edge of the push button 3 are formed. Each second engagement portion 714 protrudes further rearward than the insertion portion 713.

[0091] A rectangular cutout 715 is formed in the lower end of the main body portion 71, and a protruding portion 716 extending downward is coupled to the upper edge of the cutout 715. The protruding portion 716 has the same function as the protruding portion 412 of the first embodiment. On the other hand, the protruding portion 716 includes a rectangular upper portion 717 coupled to the upper edge of the cutout 715, and a lower portion 718 coupled to the lower end of the upper portion 717. The upper portion 717 extends downward obliquely toward the front from the upper edge of the cutout 715, and the lower portion 718 extends downward obliquely toward the rear from the lower end of the upper portion 717. Thus, the protruding portion 716 having the upper portion 717 and the lower portion 718 is formed so as to protrude toward the front in a chevron shape when viewed from the side.

[0092] As shown in Figure 11As shown, the first engaging portion 73 has a plate-shaped first portion 731 fixed to the back surface of the main body portion 71 by an adhesive or the like, and a plate-shaped second portion 732 extending downward from the upper end of the first portion 731. The second portion 732 extends obliquely downward from the upper end of the first portion 731 toward the rear, and forms a gap with the first portion 731. In addition, the first portion 731 and the second portion 732 are elastically deformably linked, and if a force is applied to the second portion 732 in the forward direction, the second portion 732 can approach the first portion 731.

[0093] The protruding member 74 is a cylindrical rod-shaped member extending in the horizontal direction, and is fixed to the back surface of the main body portion 71 between the first engaging portion 73 and the protruding portion 716 by an adhesive or the like.

[0094] The fulcrum portion 72 is formed so as to extend forward from the upper end portion of the main body portion 71 in a manner orthogonal thereto. The fulcrum portion 72 is formed in a plate shape, and a circular-arc-shaped recess portion 721 is formed in the front end portion. This recess portion 721 can be engaged from the rear to the outer peripheral surface of the discharge port 23 provided at the nozzle portion 2.

[0095] Next, the support portion 8 will be described. The support portion 8 is a member formed by bending a wire, and supports the vicinity of the lower end of the tea cup 6 as 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 portions 81 are linear portions constituting both ends of the support portion 8, and extend downward through the above-mentioned through portion 713. At the upper end of each first portion 81, a larger-outer- shaped anti-disengagement portion 811 is provided, so that the support portion 8 is prevented from disengaging downward from the through portion 713. At the lower end of each first portion 81, the second portion 82 is provided. Each second portion 82 extends obliquely from the first portion 81 toward the front and in a manner approaching each other, and further extends linearly downward. Further, the third portion 83 is provided in a manner linking the lower end portions of the two second portions 82 to each other. The third portion 83 is formed in an oval shape longer in the horizontal direction, and is formed in a circular-arc shape in plan view in a manner in which both end portions thereof protrude forward. Thus, the third portion 83 is formed in a circular-arc shape, so as to become abuttable to the outer peripheral surface of the tea cup 6.

[0096] As described above, the first portions 81 pass through the through portion 713, so that the support portion 8 is movable up and down with respect to the main body portion 71. Thus, the position of the support portion 8 becomes adjustable in correspondence with the length in the up-and-down direction of the tea cup 6.

[0097] In addition, as Figure 12As shown, in the present embodiment, the relationship between the size of the hot-water supply faucet 10 and the fitting 70 is set as follows. As shown in the figure, the distance Dl in the horizontal direction 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 distance D2 in the horizontal direction between the rear end of the protruding member 74 and the rear end of the recessed portion 721 of the fulcrum portion 72 when the main body portion 71 of the fitting 70 is disposed so as to extend in the vertical direction. Thus, as will be described later, the fitting 70 can be mounted on the hot-water supply faucet 10 using the spring pressure of the push button 3 and the first engaging portion 73, etc.

[0098] <2. Mounting method of fitting>

[0099] Next, a method of mounting the fitting 70 on the hot-water supply faucet 10 will be described. This will be described while referring to Figure 13 and Figure 14 First, the protruding member 74 and the first engaging portion 73 of the fitting 70 are pressed against the front surface of the push button 3, and then the second engaging portion 714 is engaged from the lower side in the push button 3 while pushing the push button 3. At this time, since the first engaging portion 73 is pressed in, the second portion 732 approaches the first portion 731 by elastic deformation. In this state, as shown in Figure 13 , the fitting 70 is slid upward while the recessed portion 721 of the fulcrum portion 72 is engaged in the rear end of the discharge port 23 of the hot-water supply faucet 10. During this process, if the first engaging portion 73 moves to the upper side of the push button 3, as shown in Figure 14 , since the pressing in of the second portion 732 is released, the second portion 732 returns to the original state. Thus, the second portion 732 is engaged in the upper edge of the push button 3. At this time, the protruding member 74 is disposed at a position where the front surface of the push button 3 can be contacted.

[0100] Then, if the pressing in of the push button 3 is released, as shown in Figure 12 , since the distance Dl is shorter than the distance D2 and the first engaging portion 73 is engaged in the upper edge of the push button 3 and is prevented from coming off, the fitting 70 can be prevented from coming off downward. In addition, since the second engaging portion 714 is engaged on both sides of the outer edge of the push button 3, the fitting 70 can be prevented from shifting in the horizontal direction with respect to the push button 3. Thus, the mounting of the fitting 70 is completed.

[0101] <3. Method of using hot-water supply faucet>

[0102] As described above, if the fitting 70 is mounted on the hot-water supply faucet 10, hot water is supplied in the following manner. First, as shown in Figure 15 , while the tea cup 6 into which a tea bag or tea powder has been put is brought into contact with the vicinity of the protruding portion 716 of the fitting 70 and the third portion 83 of the support portion 8, the lower end portion of the tea cup 6 pushes the third portion 83.

[0103] Therefore, as Figure 16 As shown, the front end of the fulcrum 72, specifically the recess 721 that engages with the outlet 23, becomes the fulcrum, and the fitting 70 rotates rearward. During this process, the push button 3 is pressed in by the fitting 70, and hot water is discharged from the outlet 23. The discharged hot water accumulates in the teacup 6, which is positioned below the outlet 23. If the desired amount of hot water accumulates in the teacup 6, the pressure exerted by the teacup 6 on the support 8 is released. Thus, the push button 3 is released, and the discharge of hot water from the outlet 23 stops. Then, the teacup 6 is removed from the fitting 70.

[0104] <4. Characteristics>

[0105] According to the accessory 70 configured as described above, in addition to the effects obtained by the accessory of the first embodiment, the following effects can also be obtained.

[0106] (1) Since the accessory 70 can be installed on the hot water supply faucet 10 while sliding, no tools are needed and the installation is easy.

[0107] (2) The protruding member 74 can achieve the same effect as the washer of the fitting in the first embodiment. On the other hand, since the protruding member 74 is formed in the shape of a rod, the force that pushes the fitting 70 through the cup 6 can be concentrated on the push button 3. In addition, since the protruding member 74 is formed in the shape of a cylinder extending in the horizontal direction, the curved surface of its outer peripheral surface will contact the push button 3. Therefore, although the fitting 70 is engaged with the push button 3 at an angle, the force can be efficiently transmitted to the push button 3 because the protruding member 74 is in constant line contact with the push button 3.

[0108] (3) Since the position of the support part 8 relative to the main body part 71 is adjustable, the position of the support part 8 can be changed according to the height of the teacup 6.

[0109] <5. Examples of Variation>

[0110] The embodiments of the present invention have been described above; however, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention. Furthermore, the following variations can be appropriately combined.

[0111] (1) In the second embodiment described above, the support portion 8 is designed to be movable relative to the accessory body 7, but the support portion 8 may also be fixed to the accessory body 7. The shape of the support portion 8 is not particularly limited, and it may be formed from a sheet metal rather than from wire.

[0112] (2) The structure of the first engaging portion 73 and the second engaging portion 714 is not particularly limited, and can be configured so as to be engageable with the push button 3. Thus, the shape of the push button can be appropriately changed.

[0113] (3) The protruding member 74 can also have a shape other than the above-described rod shape, and can be a member that contacts the push button 3 in a small area, such as a member that contacts the push button 3 in a point contact or a line contact. However, the protruding member 74 is not necessarily required, and can be provided as needed. In the case where the protruding member 74 is not provided, the distance D2 becomes a distance from the engagement with the push button 3 to the rear end portion of the recessed portion 721 of the fulcrum portion 72 in the fitting 70 in the dimensional relationship shown in the figure. In addition, the protruding portion 716 is not necessarily required, and can be provided as needed. Figure 12

[0114] (4) In the above-described embodiment, an example in which the fitting 70 according to the present application is applied to a hot water supply faucet for sushi rolls is described, but the present application is not limited thereto, and can be applied to various hot water supply faucets. However, in order to install a hot water supply faucet to which the fitting according to the present application is applied, it is only required to have the nozzle portion 2 having the downwardly open discharge port 23, and the push button 3 disposed below the discharge port 23 and further to the rear in the horizontal direction than the discharge port 23, and the other structures are not particularly limited.
