PROBLEM TO BE SOLVED: To provide a toilet bowl device such that dirt is hardly caught between a downstream end of a movable trap and an inner surface of a housing.SOLUTION: A downstream end 31 of a movable trap 3 moves on an upper position 60 where water can be reserved in a bowl part 2 and a lower position 64 where water can be discharged, and a predetermined trajectory 6 between them. An inner surface 40 of the housing 4 which houses the movable trap 3 has a first gap 71 within a first inner surface range 41 opposed to a first trajectory range 61 including the upper position 60 in the predetermined trajectory 6, and also has a second gap 72 within a second inner surface range 42 opposed to the second trajectory range 62 along the second trajectory range 62 connecting with the first trajectory range 61. A second distance range has an upper-limit value for suppressing dirt larger than a predetermined size in the bowl part 2 from passing.SELECTED DRAWING: Figure 6 |
