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.

Abstract: Provided is a flush toilet device in which flushing can be effectively performed with small amount of flush water by accurately setting opening times for individual drain valves. A flush toilet device (1) of the present invention includes a flush toilet main body (2), a flush water tank (4), a first drain valve (10) configured to control flush water from a rim spout port (2d) by opening and closing a first drain port (4b) provided in the flush water tank, a second drain valve (12) configured to control flush water from a jet spout port (2e) by opening and closing a second drain port (4c) provided in the flush water tank, and a hydraulic drive mechanism (16) configured to open the first or second drain valve by using water supply pressure of flush water supplied from a tap water supply line to the flush water tank.
