  • the support portion 8 is composed of a pair of first site 81, a pair of second site 82, and a pair of third site 83.
  • the first portion 81 is a linear portion constituting both ends of the support portion 8, and is inserted through the above-mentioned insertion portion 713 and extends downward.
  • a retaining portion 811 having a large outer shape is provided at the upper end of the first portion 81, thereby preventing the support portion 8 from detaching downward from the insertion portion 713.
  • a second portion 82 is provided at the lower end of each first portion 81.
  • Each second site 82 extends forwardly from the first site 81 and diagonally so as to be close to each other, and further extends linearly downward from there.
  • a third portion 83 is provided so as to connect the lower ends of both second portions 82 to each other.
  • 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 a plan view so that both ends thereof project forward. By forming the third portion 83 in an arc shape in this way, it is possible to abut on the outer peripheral surface of the teacup 6.
  • the support portion 8 By inserting the first portion 81 into the insertion portion 713 as described above, the support portion 8 can move up and down with respect to the main body portion 71. As a result, the position of the support portion 8 can be adjusted according to the length of the teacup 6 in the vertical direction.
  • the dimensional relationship between the hot water supply faucet 10 and the attachment 70 is set as follows.
  • 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 when the main body portion 71 of the attachment 70 is arranged so as to extend in the vertical direction.
  • the distance between the rear end of the protruding member 74 and the rear end of the recess 721 of the fulcrum 72 is shorter than the horizontal distance D2.
  • the attachment 70 can be attached to the hot water supply faucet 10 by using the urging force of the push button 3 and the first engaging portion 73.
  • the distance D1 is shorter than the distance D2, and the first engaging portion 73 engages with the upper edge of the push-in button 3. It prevents the attachment 70 from coming off downward by preventing it from coming off. Further, 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 being displaced horizontally with respect to the push button 3. In this way, the attachment of the attachment 70 is completed.
  • the tip of the fulcrum portion 72 that is, the recess 721 that engages with the discharge port 23 serves as a fulcrum, and the attachment 70 turns backward.
  • the push button 3 is pushed by the attachment 70, and hot water is discharged from the discharge port 23.
  • the discharged hot water is accumulated in the teacup 6 arranged below the teacup 6, but when a desired amount of hot water is accumulated in the teacup 6, the pressing of the support portion 8 by the teacup 6 is released.
  • the push-in button 3 is released, and the discharge of hot water from the discharge port 23 is stopped. After that, the teacup 6 is removed from the attachment 70.
  • attachment 70 can be attached to the hot water supply faucet 10 while sliding, there is no need to use a tool and the attachment is easy.
  • 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 for pressing the attachment 70 through the teacup 6 can be concentrated on the push button 3. Further, since the projecting member 74 is formed in a columnar shape extending in the horizontal direction, the curved surface of the outer peripheral surface thereof comes into contact with the push button 3. Therefore, even if the attachment 70 touches the push button 3 while tilting, the outer peripheral surface of the projecting member 74 always makes line contact with the push button 3, so that the force can be efficiently transmitted to the push button 3.
  • the support portion 8 is movably provided 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 may be formed of a plate material instead of a wire material.
  • the configuration of the first engaging portion 73 and the second engaging portion 714 is not particularly limited, and is not particularly limited as long as it is configured to engage the push button 3. Therefore, it can be appropriately changed according to the shape of the push button.
  • the protruding member 74 may have a shape other than the rod shape as described above, and may be a member that comes into contact with the push button 3 in 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 needed. When the projecting member 74 is not provided, the distance D2 is the distance from the portion of the attachment 70 in contact with the push button 3 to the rear end of the recess 721 of the fulcrum portion 72 in relation to the dimensions shown in FIG. Further, the protruding portion 716 is not essential, and may be provided as needed.
  • the present invention is not limited to this, and the attachment 20 is applied to various hot water supply faucets. Can be done.
  • the hot water supply faucet to which the attachment according to the present invention is attached has at least a nozzle portion 2 having a discharge port 23 that opens downward, below the discharge port 23, and horizontally behind the discharge port 23. It suffices to have a push button 3 to be arranged, and other configurations are not particularly limited.
