An end face polishing apparatus with improved polishing precision regardless of the length of ferrules when end faces of the ferrules are polished is provided. In an end face polishing apparatus polishing a rod-shaped member mounted at a polishing fixture by pressing the rod-shaped member against a lapping member on a lapping machine provided on a surface plate that is supported at the main body of the apparatus to rotate and rock, there are a plurality of rod-shaped guide members provided at the polishing fixture radially outwardly projecting and a tubular member capable of supporting the polishing fixture through the guide members on the surface plate. In this way, the guide member sat the polishing fixture and the tubular member abut against each other so that the movement of the polishing fixture in the pressing direction is restricted.
An end face polishing apparatus polishing a rod-shaped member mounted at a polishing fixture by pressing the rod-shaped member against a lapping member on a lapping machine provided on a surface plate, said surface plate being supported at the main body of the apparatus to rotate and rock, comprising:
