Abstract: In an optical connector for use in connecting an optical fiber, a housing defines an optical axis extending in a predetermined direction. For positioning the optical fiber along the optical axis, a ferrule is accommodated in the housing to be movable in the predetermined direction. The housing further accommodates a fixing member engaged with the housing in the predetermined direction. Between the ferrule and the fixing member, an elastic member is interposed to urge the ferrule towards one side in the predetermined direction. In addition, the housing has a guide groove extending in the predetermined direction. The fixing member has a guide portion protruding through the guide groove to the outside of the housing.
