PROBLEM TO BE SOLVED: To make only the polishing member of a rotary polishing fixture freely mounted/demounted, and furthermore, prevent the polishing member from falling down while it is being used. SOLUTION: A rotary polishing fixture 50 is formed out of a separate center member 5, and of a polishing member 6. Both the members are rotated so as to be engaged with each other by means of the groove part 5f of the center member 5 and the projected part 6d of the polishing member 6, and can be freely mounted/demounted. The center member 5 is fixed to the rotary shaft 71 of a grinder 70 by a fixing screw 73, and by this constitution, the polishing member 6 can be removed as the center member 5 is left as is fixed to the rotary shaft 71. A cut-out part 6k is provided for the middle part of the projected part 6d, and a locking projected part 5k is also provided for a place corresponding to the aforesaid middle part. When the polisher is suspended and the like while polishing is being performed, the polishing member 6 is revolved in the direction that an engagement with the center member 5 is released, however, when the end part of the projected part 6d abuts against the partitioning part 5g of the other groove part, the polishing member is prevented from falling down because the aforesaid cut-out part 6k does not agree in position with the locking projected part 5k. |
