PROBLEM TO BE SOLVED: To provide a suction port body and a vacuum cleaner for improving dust-collecting efficiency by a window in the suction port body of a circulation type vacuum cleaner which executes cleaning while returning the exhaust air of an electric blower to the suction port body. SOLUTION: In the state of connecting a suction port body to a vacuum cleaner, the exhaust air of an electric blower is returned to the suction port body. Blow out openings 53 are bored at a blow out chamber 47 formed in the suction port body and communicated with the exhaust side of the electric blower. These openings 53 are opened and closed by opening/closing bodies 54. At the time of blowing away dust by a wall, etc., the openings 53 are opened by the bodies 54 to blow out returning air from these blow out openings.
