<P>PROBLEM TO BE SOLVED: To improve safety in a rotation brush to be used for a floor suction tool. <P>SOLUTION: In the floor suction tool including a case forming an external shell, the rotation brush for raking out dust from a surface to be cleaned by rotational driving, and a driving portion arranged in the case and ritationally driving the rotation brush, the driving portion includes an introduction opening for introducing an air flow to an inner part, an exhaust port for exhausting the air flow toward the inner part of the case, a turbine to be driven by rotation by the air flow positioned between the introduction opening and the exhaust port, and driving force transmission means for transmitting the rotation driving force of the turbine to the rotation brush. The case includes a rotation brush storage chamber for allowing the rotation brush to be rotatably stored, a suction port opened in the rotation brush storage chamber so as to suck dust, a dust collection blow passage for allowing the dust sucked from the suction port to flow down to the external part of the case, a space for allowing the air flow exhausted from the exhaust port to flow down, and an opening for communication between the space and the rotation brush storage chamber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
