Abstract
The present invention provides an end face polishing device capable of improving a polishing accuracy by polishing an end face of an optical fiber ferrule with adjusted polishing pressure. An end face polishing devicefor optical fiber ferrule for polishing an end face of an optical fiber ferrule by applying a polishing pressure between a polishing platedriven by a polishing drive shaft and an optical fiber ferrule held by a holding portion. The end face polishing device for optical fiber ferrule has: a bearing portion for allowing the polishing plateto 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 portionfor movably supporting the polishing plateon a base portionto apply the polishing pressure to the holding portionby allowing the polishing plateto move in the axial direction; a pressing drive sourcefor adjustably outputting a driving force to apply the polishing pressure; and a pressing force transmission mechanismfor transmitting the driving force output from the pressing drive sourceas a pressing force in the axial movement direction of the polishing plate
