| description | PROBLEM TO BE SOLVED: To obtain a surface polishing device excellent in elevation driving performance, which supports an upper platen in a well-balanced manner. SOLUTION: An elevating device 8 driving the elevation of the upper polishing plate 1 between a polishing position and a non-polishing position is provided with: three elevation driving mechanism parts 8A operated in synchronization; and a connection mechanism part 8B connecting these elevation driving mechanism parts 8A and the upper polishing plate 1. The elevation driving mechanism parts 8A are disposed in parallel at 120° intervals at positions surrounding the upper polishing plate 1 of a machine body. The connection mechanism part 8B is provided with three connection arms 12 extended in a radial direction at 120° intervals from a supporting part 11 supporting the upper polishing plate 1 and connected with the elevation driving mechanism parts 8A.
