<p>PROBLEM TO BE SOLVED: To provide a toilet bowl unit having a cover mechanism with a cover mounted on a base member via ratchet mechanism capable of preventing looseness of the cover in a state locked to the base member.SOLUTION: The toilet bowl unit includes: a base member 2; a cover 4 mounted onto the base member 2; and a ratchet mechanism 5 provided to the base member 2 and the cover 4. The ratchet mechanism 5 is arranged to lock the cover 4 to the base member 2 and to unlock the cover 4 when the cover 4 in a lock state is pressed toward the base member 2. The cover 4 has a thin wall part 40 which is formed to be thinner than other part around the same in a part of the cover 4; and a movable part 41 which is movable in a thickness direction of the cover 4 due to an elastic deformation of the thin wall part 40. The ratchet mechanism 5 is provided to the rear face of the movable part 41 and the base member 2.</p> |
