PROBLEM TO BE SOLVED: To increase both the positioning strength and water-stopping strength of a device case of a bidet with respect to a rim of a toilet bowl body. SOLUTION: The right-and-left projected side walls 11 which are continuous with a rim 4 and are projected toward the rear B are projected in the rear B position which is more rearward than the rear part 4a of the rim positioned at the rear of a bowl part 3, and a storage opening 12 is formed between the projected side walls 11. The storage opening 12 can store the device case 8 and is opened at the rear B. A pair of engagement parts 13 is provided in the right-and-left diagonal positions P1, P2 which are displaced with respect to each other in the front A and the rear B on both of the inner surfaces 11a of the storage opening 12 which are opposed to each other. Then a pair of parts 14 to be engaged which is engaged with the pair of engagement parts 13 in a detachable manner is provided to diagonal positions which individually correspond to the pair of engagement parts 13 at both the right side and the left side of the device case 8 which is stored in the storage opening. The front end of the device case 8 of the toilet bowl device 1 is brought into intimate-contact with a seal member 15 arranged between the rear part 4a of the rim and the device case 8.
