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.

Disclosed is a vacuum breaker having further enhanced reliability. The vacuum breaker comprises: a main body having a water inlet (), a water outlet (), a water passage () for fluidically connecting the water inlet and the water outlet, and a first ambient-air intake port () and a second ambient-air intake port () for allowing the water passage to fluidically communicate with ambient air therethrough; a first valve element (); and a second valve element () disposed downstream of the first valve element. The first valve element is designed to be movable between a first position allowing the water inlet to fluidically communicate with a zone of the water passage between the first and second valve elements, when water is permitted to pass through the water passage, and a second position allowing the first ambient-air intake port to fluidically communicate with the zone of the water passage between the first and second valve elements, when water is inhibited from passing through the water passage. The second valve element is designed to be movable between a first position allowing the zone of the water passage between the first and second valve elements to fluidically communicate with the water outlet, when water is permitted to pass through the water passage, and a second position allowing the second ambient-air intake port to fluidically communicate with the water outlet, when water is inhibited from passing through the water passage.
