Abstract
An end face polishing device for optical fiber ferrule for polishing an end face of an optical fiber ferrule by applying a polishing pressure between a polishing plate driven by a polishing drive shaft and an optical fiber ferrule held by a holding portion. The end face polishing device has: a bearing portion for allowing the polishing plate to rotate relatively around the polishing drive shaft and to move relatively to the polishing drive shaft in an axial direction; a polishing plate guide supporting portion for movably supporting the polishing plate on a base portion to apply the polishing pressure to the holding portion by allowing the polishing plate to move in the axial direction; a pressing drive source for outputting a driving force to apply the polishing pressure; and a pressing force transmission mechanism for transmitting the driving force output from the pressing drive source as a pressing force in the axial movement direction of the polishing plate.
