PROBLEM TO BE SOLVED: To provide a disk cleaner which efficiently prevents shavings from entering a motor room. SOLUTION: A disk-polishing room (20S) in which a turntable on which a disk (1) is put is arranged and a motor room (12S) in which motors (35A and 35B) provided with polishing tools (5A and 5B) for polishing the surface to be polished of the disk 1 are installed in the output shaft (35a) through a polishing-tool holding tools (50A and 50B) are arranged to be next to each other. The output shaft (35a) of the motors (35A and 35B) is inserted in the disk-polishing room (20S) through shaft-play apertures (12c and 12c) formed in the bottom plate (12C) of the motor room (12S), and a cylindrical elastic body (200) consisting of gum or the like, which is extendable in the direction of height, is arranged so that the output shaft (35a) can be surrounded and the blockade between the bottom plate (12C) and the motors (35A and 35B) can always be made in order to prevent the shavings (K) from entering the motor room (12S) through the shaft-play apertures (12c and 12c). |
