PROBLEM TO BE SOLVED: To provide a small-sized and light-weight suction port body capable of enlarging the driving power of a rotary cleaning body, reducing noise, enlarging the dimension of the left-to-right width of the rotary cleaning body compared to the left-to-right width of the suction ort body and widening a cleanable area. SOLUTION: The rotary cleaning body (301, 302-305) is arranged so as to divide a chamber to dispose the rotary cleaning bodies into a chamber part 309 on the side of a floor surface opening part 307 and a chamber part 308 on the side of a joint opening 306 by a plane including the rotary shaft. Also, the vanes 302-305 of the rotary cleaning body are constituted so that a rotation radius length varies according two the peripheral direction.
