PROBLEM TO BE SOLVED: To upgrade the efficiency of the work of winding the polishing clothes and the durability of the apparatus itself in a gripper for the polishing clothes. SOLUTION: A grip member 104 is rockably supported with a support bar member 110 and a protrusion member 102 is provided in proximity to the rear rim part 107 thereof. When a tensile force works on the polishing cloth 20 in the direction of the arrow A, the polishing cloth 20 is spread tensely to be raised at the rear rim part 107 thereof while the front rim part 106 is pressed against a resistance plate 120 conversely to increase the gripping force of the polishing cloth 20. But the increasing action of the gripping force does not occur even when the polishing cloth 20 is pulled from the direction of the arrow B in the winding thereof thereby enabling the winding of the polishing cloth 20 without the operation of an operation lever 113.
