PROBLEM TO BE SOLVED: To improve the space and energy saving performance and the assembling performance of end face polishing device, and improve their machining precision by suppressing turbulence in polishing loci. SOLUTION: In polishing operation, this end face polishing device rotates and swings a polishing disk 31 with a polishing member and presses a rod member held on a fixing jig disk against the polishing member of the polishing disk 31 thus rotated and swung. The polishing device includes a drive mechanism, which comprises a rotating shaft 33 with one end fixed to the polishing disk 31 so as to be rotatable and revolvable together with it, a revolving shaft 37 for holding the rotating shaft 33 rotatable in an offset position, revolving shaft support means 43 for supporting the revolving shaft 37 rotatably, drive means 50 for rotating the revolving shaft 37, a first gear 39 fixed to or near to the other end of the rotating shaft 33, and a second gear 49 disposed along the movement locus of the first gear 39 so as to engage with it. The rotation of the revolving shaft 37 by the drive means 50 revolves the rotating shaft 33, and the engagement between the first and second gears 39 and 49 rotates the rotating shaft 33.
