Abstract: A flush toilet 1 has a toilet flushing tank device 7 for discharging flushing water to a toilet bowl 2. This tank device is built into a tank storage region 5 to the rear of the toilet bowl 2, and comprises a flushing water tank 8 and a jet pump 13 disposed submerged in this flushing water tank 8. Flushing water (operating water) is supplied to this jet pump 13 via a flush valve 11 and a pipe 12 downstream from this valve. The jet pump 13 comprises a spray nozzle 131 and a throat 132 opposite thereto. Because the jet pump 13 is connected directly to a pipe 14, all of the flushing water jetted from the jet pump 13 passes directly to the pipe 14, and is guided by this pipe 14 to a rim water channel 4b.

Abstract: A toilet accessory (10) having readily detachable toilet seat (14) and toilet lid (16). A hinge shaft (74) is supported by a pair of posts (72) to protrude away from the housing (12). The hinge portions of the toilet seat and the toilet lid are provided with elastic collars (84) of C-shaped cross-section and are snap-fitted on the hinge shaft (74). When the toilet seat and the toilet lid are to be removed for washing or cleaning, they can be readily dismounted only by pulling with hands. To re-install, the hinge portions readily snap-fit on the hinge shaft by bringing the elastic collars (84) in contact with the hinge shaft (74) and by pressing down the hinge portions. Since the hinge shaft (74) and the posts (72) are exposed out of the housing (12), they can be easily accessed for cleaning.
