<p><P>PROBLEM TO BE SOLVED: To provide a floor treatment machine in which holding force of a washing tool is sufficiently improved while suppressing increase in the number of components, and which has improved durability. <P>SOLUTION: The floor treatment machine is configured to perform floor treatment work by bringing a washing tool 5 to be rotated by a motor 3 into contact with a floor, and includes a sleeve 26 attached downwards to a rotary shaft 25 of the motor 3 and a boss 43 attached to the washing tool 5 and provided with an upward recess 52 into/from which the sleeve 26 can be inserted and detached. On the outer peripheral surface 28 of the sleeve 26, a plurality of pawl parts 33 project radially. On the inner peripheral surface 53 of the boss 43, a plurality of pawl parts 54 project radially in association with the pawl parts 33 of the sleeve 26. By the engagement of the pawl parts 33 of the sleeve 26 with the pawl parts 54 of the boss 43, the rotary shaft 25 of the motor 3 and the washing tool 5 are connected and the rotation of the motor 3 is transmitted to the washing tool 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
