Abstract: A float rise speed control tank in a flush toilet is formed so that when the flush water level inside a flush water tank rises and the flush water level reaches a window due to supply of flush water into the flush water tank by a water supply device, the inflow into the float rise speed control tank by flush water in the flush water tank from a window formed above the bottom edge part of the float causes the rise speed of the flush water level in the float rise speed control tank to increase more than the rise speed of the flush water in the flush water tank.
