ABSTRACT:
An optical connector has a ferrule comprises of a cylindrical body for supporting an optical fiber, and a flange member having an end portion connected to a first end of the cylindrical body and a flange part projecting from the end portion. A holding member supports the ferrule and has an engaging part. A rotation positioning part is formed in the flange part of the flange member for positioning the flange part relative to the holding member to provide a first clearance between the rotation positioning part and the engaging part of the holding member for restricting rotation of the ferrule about the fiber optical axis relative to the holding member. A rotation allowing part is formed in the flange part of the flange member and spaced from the engaging part of the holding member to provide a second clearance therebetween greater than the first clearance for allowing rotational movement of the ferrule so as to permit the ferrule to incline in a direction transverse to an axis of the optical connector.
