Abstract: A toilet seat attachment structure is used for attaching a toilet seat unit on a toilet bowl. The structure includes a bolt with an axis portion, an abutting member disposed around the axis portion, an expanding member situated adjacent to the abutting member, and a nut member situated adjacent to the expanding member and engaging the axis portion. The abutting member has a shaft portion with a through-hole, and a flange formed on an upper periphery of the shaft portion. The axis portion passes through the abutting member and the expanding member, and engages the nut member. A friction member is disposed outside the expanding member. When the bolt is rotated, the nut member ascends on the axis portion, so that the expanding member gradually expands the diameter. Accordingly, the frictional member is enlarged to frictionally engage with an attachment hole of a toilet bowl.

Abstract: A sanitary device for washing private parts of a person sitting on a toilet bowl includes a first nozzle positioned within the toilet bowl and having a main passage and an auxiliary passage. The main passage has at least one main aperture and the auxiliary passage has at least one auxiliary aperture, the main and auxiliary apertures being located at a distal end of the first nozzle and being directed to a private part of a person sitting on the toilet bowl. A second nozzle is positioned within the toilet bowl and has a third passage having at least one third aperture located at a distal end of the second nozzle and being directed to another private part of a person sitting on the toilet bowl. A regulating device is fluidically disposed between a supply of water under pressure and each of the main passage, the auxiliary passage and the third passage for establishing a variable degree of fluid communication between the water supply and at least one of the main, auxiliary and third passages.
