PROBLEM TO BE SOLVED: To provide a flush toilet bowl having a rim inner wall part with an inclined upper rim inner wall surface formed by an inner side in an upper area of the rim inner wall part that inclines downward for improving visibility of a user and cleanliness for the user, the flush toilet bowl suppressing splashing due to centrifugal force of flush water to outside of a bowl part from an inner surface formed relatively at a low height along the inclined upper rim inner wall surface.SOLUTION: A flush toilet bowl 1 of the present invention includes a bowl part 8 having a feces receiving surface 44 and a rim part 46, a water discharging part 14 that discharges flush water into the bowl part, and a water supply device 6. The rim part includes a rim inner wall part 52 that forms an inner periphery of the rim part. The rim inner wall part 52 includes an inclined upper rim inner wall surface 52a formed by an inner side in an upper area of the rim inner wall part that inclines downward, and an inner surface 52b that extends linearly in a vertical direction to the inclined upper rim inner wall surface. The water supply device 6 includes constant flow means 16 for discharging a prescribed constant flow amount of flush water from the water discharging part.SELECTED DRAWING: Figure 6 |
