To provide a chair provided with a toilet bowl with a flushing device and a body-cleaning device which can be used indoors or the like.

The lower part of the seating part 1 of the chair A is provided with the toilet bowl 6, a separation device 7, an excrement-treatment tank 8, and a urine-treatment tank 9. The toilet bowl 6 has an offtake 61 at its bottom, and the separation device 7 achieves separation between the excrement and the urine which are voided into the toilet bowl 6. Then the excrement-treatment tank 8 decomposes the excrement separated by the separation device 7 by microorganisms, and the urine-treatment tank 9 treats the urine separated by the separation device 7. Then the separation device 7 is provided with a urine-receiving container 71 and an excrement-guide tube 75. The urine-receiving container 71 makes the urine, which is voided into the toilet bowl 6, flow along the inner wall 62 of the toilet bowl 6, and is connected to the offtake 61 of the toilet bowl 6. The urine-receiving container 71 is spread downward in a trumpet form, and has a bottom. Then the excrement-guide tube 75, penetrating the bottom of the urine-receiving container 71, is provided so that its tip is placed away from the inner wall of the urine-receiving container 71. The excrement-guide tube 75 is normally closed by a shutter 73, and is opened only at the use for excretion.
