PROBLEM TO BE SOLVED: To enable suction of solid dust on a floor surface at the back of a suction port body during retreat of the suction port body, and to prevent the dust sucked from the front side from being easily discharged backward from the suction port body during advance of the suction port body.SOLUTION: A suction port body of a vacuum cleaner includes: a first rotary cleaning body having a rotary shaft substantially parallel with a cleaning surface; a suction chamber for supporting the first rotary cleaning body; and a second rotary cleaning body having a shaft parallel with the rotary shaft and coming into contact with the cleaning surface, at the back of the first rotary cleaning body. On a surface of the second rotary cleaning body, a brush body or an elastic body is provided, and the brush body or the elastic body is provided so as to come into contact with one part of the suction body, and it is provided being inclined in a circumferential direction so that, during retreat of the suction port body, a rotational operation of the second rotary cleaning body is permitted, and, during advance, the rotational operation of the second rotary cleaning body is restricted. |
