PROBLEM TO BE SOLVED: To dispense with cleaning work preceding to scrubbing work even if scrubbing a floor while turning to the right and left. SOLUTION: A first shaft S1 and a second shaft S2 coaxially fixed with a first gear G1 and a second gear G2, which are geared with each other on the outer circumferential face, are rotationally supported to a frame F, and the first shaft S1 among them is fixed to the tip of a first arm A1 extending to the front of a floor scrubber. The second shaft S2 is fixed with the rear end of a second arm A2 having a cleaner C at its tip. The frame F is provided with a roller R coming into contact with the floor face in the rear part of the first shaft S1. The frame F and the second arm A2 are rotationally turned around the first gear in the direction where the floor scrubber changes the advancing direction. COPYRIGHT: (C)2007,JPO&INPIT
