PROBLEM TO BE SOLVED: To provide western-style toilet stool equipment capable of being also easily applied to western-style toilet stool equipment which can reduce the whole capacity to a small one, which can enhance a degree of freedom of arrangement of equipment in a tank cover, and which enables the uplift of front half parts of the tank cover and a base plate. SOLUTION: A lower part 51a of a float valve device 50 is inserted into a feedwater receiving port 13 of a rear top surface of a western-style toilet stool 10. A peripheral edge of an opening 31 of a bottom surface of a low-tank retainer 30 is positioned inside with respect to a peripheral edge of the port 13. In the retainer 30, a low tank 40 is arranged in such a manner that an air layer with a thickness of the order of 2-3 mm is formed between its bottom surface and the bottom surface of the retainer 30. Dew condensation water, which occurs on the outer surface of the lower tank 40, flows down into the port 13 from the opening 31 in a dripping manner, and is discharged into a toilet bowl 11 via a rim water passage 12.
