<p>PROBLEM TO BE SOLVED: To provide a groove polishing device and an elevator device which can improve efficiency in polishing work.SOLUTION: A groove polishing device for polishing a sheave groove formed in a sheave is installed below the sheave at all times, and comprises a stand, a lever, a pressing force adjustment mechanism, and a polishing jig. The stand supports the lever rotatably. The lever is placed at a position deviated from a position immediately under the sheave groove. One end of the lever is supported rotatably on the stand, and the other end is supported on the pressing force adjustment mechanism. A support rod is provided between the one end and the other end of the lever. The support rod supports the polishing jig positioned immediately under the sheave groove. The pressing force adjustment mechanism has a structure which rotates the lever with the one end of the lever as a fulcrum by moving the other end of the lever upward or downward. The polishing jig is supported on the support rod, polishes the sheave groove by contacting with the sheave groove when the other end of the lever moves upward, and is separated from the sheave groove when the other end of the lever moves downward.</p> |
