(54) Suction brush for vacuum cleaner


(57) A suction brush for a vacuum cleaner includes blocking members mounted front and rear, to a brush body bottom surface to seal off the periphery of a suction inlet formed thereon and to generate a high suction force between a surface to be cleaned and the suction inlet during cleaning, wherein the front blocking member is pivotably mounted to the brush body when one end thereof is connected thereto, and includes blocking arms to maintain the high suction force between the suction inlet and the surface to be cleaned while being alternately brought into close contact therewith when the brush body moves forwards or backwards; and the first blocking arm includes a plurality of air suction apertures to restrict passage of air flowing into the suction inlet while the first blocking arm is in close contact with the surface to be cleaned when the brush body moves forwards.
