<p>A rotary polishing device by which the number of members which are discarded when the polishing member is worn out is decreased, and hence bad influence upon the environment is curbed. A polishing member holder (11) and a central member (12) are fixed to each other separably by a threaded means or some other locking means. The polishing member holder (11) alone can be discarded by disengaging the holder (11) from the central member (12) of a device body (1), and the central member (12) can be reused as it is.</p> |
