By the way, the cleaning water is stored in the water supply tank by the ball tap valve device so as to reach a predetermined water level. However, a hand-washing bowl and a spout are provided at the upper part of the water supply tank. When it is provided so that it can be washed by hand, part of the water discharged from the ball tap valve device is sent to the water discharge faucet, and the rest is directly supplied into the water supply tank. However, in the case of simple flushing, the amount of flush water supplied to the toilet bowl is small and the amount of water supplied to the water supply tank is also small, and as described above, some of the water supplied to the water supply tank is discharged from the ball tap valve device. However, when used for hand washing, there is a problem that water for hand washing runs short. On the contrary, if all the water is supplied from the ball tap valve device to the spout for faucet for hand washing, there is a problem that it takes time to supply the water into the water supply tank during the main washing.

The present invention has been made in view of the above-mentioned points, and it is possible to supply sufficient hand-washing water even during simple washing and to supply water to the water tank in a short time during main washing. The task is to
