A flush toilet apparatus includes a toilet body that includes a rim water spout port, a tank that stores washing water, a rim side water supply channel that supplies washing water to the rim water spout port, a tank side water supply channel that supplies washing water to the tank, a flow channel switching part that adjusts an amount of washing water that is supplied to one or both of the rim side water supply channel and the tank side water supply channel, and an electrical power failure detection part that detects electrical power failure, wherein, in a case where electrical power failure is caused when washing water is supplied to the tank side water supply channel, the flow channel switching part decreases washing water that is supplied to the tank side water supply channel and increases washing water that is supplied to the rim side water supply channel.

Flush toilet apparatus

A water supply mechanism includes a switching part that executes switching between water supply and water shut-off, a manual operation valve on the switching part that is capable of a manual operation thereof, and a pushing member that pushes the manual operation valve to provide a valve-closed state. The manual operation valve is pulled in a direction opposite to a pushing direction of the pushing member to provide a valve-opened state. The manual operation valve includes a plunger, an external cylinder member that encloses the plunger, a first engaging point in the external cylinder member, and a fixation part in the external cylinder member that fixes the plunger in the valve-closed state or the valve-opened state. The plunger moves beyond the first engaging point as the manual operation valve is pulled, and is fixed in the valve-opened state as a pull of the manual operation valve is released.
