Therefore, the water flows down while rotating in the discharge port 33, and the discharge of the water from the discharge port 33 is performed smoothly, and the water does not stay. Therefore, the flow of water in the medicine supply device 1 becomes irreversible, and the water that has flowed in and eluted the medicine does not flow out to the hand washing section 62. Therefore, even when the water eluted with the drug has a color, the color does not remain in the hand washing portion 62, and the appearance is not deteriorated due to the color remaining.

As described above, since S2 / S1 is set to a value substantially equal to V2 / V1, the discharge of water from the drain hole 65 and the discharge of water from the discharge port 33 are:
It is ensured that both are performed smoothly without causing stagnation.

The length L1 of the discharge port 33 is equal to the length of the drain hole 65.
