Abstract: A urinal includes a bowl part, a water spout part, a functional part, and a housing part. The bowl part receives urine. The water spout part spouts washing water to the bowl part. The functional part supplies washing water to the water spout part. The housing part is formed on an upper part of the bowl part at a back side thereof and houses the functional part therein. The functional part includes a vacuum breaker that is provided in a water supply channel to the water spout part and prevents a backward flow of sewage water from the water spout part, and a diaphragm that is provided at an upstream side of the vacuum breaker and switches between a water stop state where the water supply channel is closed and a water supply state where the water supply channel is opened. The vacuum breaker is arranged above the diaphragm.

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.
