Claims

[Scope of Claim for Utility Model Registration] (1) Comprising a suction port body and a rotating brush that is rotatably supported within the suction port body with the left and right directions as rotational axis directions and has brush bristles protruding from the outer circumferential surface; A suction port is formed by opening the lower surface and the front surface of the suction port body facing the rotating brush, and the front end of the rotation locus of the tip of the bristles of the rotating brush is directed forward from the front surface of the suction port main body. the rotary brush has an arcuate cross-sectional shape in a direction perpendicular to the rotational axis of the rotary brush having a diameter larger than a diameter of a rotation locus of the tip of the bristles of the rotary brush, and rotates to open and close the front surface of the suction port; A plate is rotatably supported on the suction port body around a rotation axis coaxial with the rotation axis of the rotating brush, and the rotation plate is located on the lower side when the front surface of the suction port is closed. A suction mouth body for a vacuum cleaner, characterized in that the suction mouth body of a vacuum cleaner is rotatable until the end edge is positioned above the rotary brush and behind the front end of the rotation locus of the tip of the bristles of the rotary brush. (2) A suction port main body, and a rotating brush that is rotatably supported within the suction port main body with the left and right directions as rotational axis directions and has brush bristles protruding from the outer peripheral surface, and the suction port faces the rotating brush. A suction port is formed by opening a lower surface and a front surface of the main body, and a cross-sectional shape in a direction perpendicular to the rotation axis of the rotary brush has a diameter larger than a diameter of a rotation locus of a tip of the bristles of the rotary brush. A rotary plate having an arc shape and opening and closing the front surface of the suction port is rotatably supported on the suction port body about a rotation axis coaxial with the rotation axis of the rotary brush, and the rotation plate has an arc shape in cross section. A suction port body for a vacuum cleaner, characterized in that a soft member is provided on the entire outer peripheral surface of the rotating plate.
