PROBLEM TO BE SOLVED: To enhance dust collecting performance with utilizing circulation air used for rotating a rotary cleaning body. SOLUTION: In this suction port body, a communication pipe communicated with a cleaner main body side is provided in a width-directional central part of a suction port body main part having a suction port 91 for sucking air on a cleaned surface in accompany with air circulation. A rotary cleaning body 53 having plural twisted blades (cleaning members) 102, 103 is attached to be freely rotatable inside the main part, facing to the suction port 91. A circulation flow blowing-out port 54 comprising a slit for blowing circulation air to the blades 102, 103 from an upper side is provided in the main part to be extended in a width direction thereof. The air blown out from the blowing-out port 54 is thereby blown to one portion of the blades 102, 103 all the time to rotate the cleaning body 53, and is guided by the twisted blades 102, 103 upto ends in twisted directions thereof to be blown out on the cleaned surface.
