Abstract
The present invention has an object to provide a rotating polishing tool with high durability that can finish a polished surface with desired surface roughness. As means thereof, a substantially cylindrical polishing memberis constituted by a pair of polishing unitsat opposite ends, and an intermediate portionprovided between the pair of polishing units. The polishing memberis rotatably supported around the central axis thereof, and polishes a polished surface with a peripheral surface thereof. The polishing unitincludes a plurality of abrasive cloth/paper sheetspressingly held by an inner metal fitting, and forms peripheral edges of the abrasive cloth/paper sheetsinto a serpentine shape. The intermediate portionincludes a plurality of laminated abrasive cloth/paper sheetsaxially pressingly held by the polishing units. The intermediate portionis caused to fit along the polishing unitsto form the peripheral edge of each abrasive cloth/paper sheetinto a serpentine shape. No clearance is created between the abrasive cloth/paper sheets, thereby stabilizing surface roughness of the polished surface and increasing durability of the polishing member
