Claims

[Claims for Utility Model Registration] 1. A suction chamber containing a rotating brush, a turbine chamber containing an air turbine, a first communication hole connecting these suction chambers and the turbine chamber, and a first communication hole that communicates with the turbine chamber without passing through the turbine section. a second communication hole that connects the vacuum cleaner main body side of the turbine chamber and the suction chamber; a closing plate that opens and closes the first or second communication hole; a switching lever that moves the closing plate; and a switching lever that moves the closing plate; A belt is provided that is stretched between the shaft of the brush and the shaft of the air turbine to transmit power, and the belt is pressed against the belt between the shaft of the rotating brush and the shaft of the air turbine and its position is adjusted according to the tension of the belt. a pulley having one end of its shaft rotatably locked to a fulcrum such that the belt changes; and when the tension of the belt increases and the position of the pulley changes, the first communication hole is closed or the second communication hole is closed. A suction tool for a vacuum cleaner equipped with a transmission lever that moves a closing plate in an opening direction. 2. The suction tool for a vacuum cleaner according to claim 1, characterized in that the pulley is pressed against the tension side of the belt.
