Abstract

A fixing structure of an optical cable, comprising a tubular crimping ring (2) and a tubular crimping seat (3) disposed on the inside of the crimping ring. A projected part (3b) swelled to the outside at a radius equal to or more than a radius up to the outer periphery of the sheath (12b) of the optical cable (12) to the outer surface of a tension member wire (12c) is formed on the outer peripheral part of the crimping seat between the front end face of the crimping seat and the front end of the sheath (12b). The sheath (12b) and the tension member wire (12c) of the optical cable (12) or either of the sheath and the tension member wire is interposed between the crimping ring and the crimping seat, the optical fibers of the optical cable are inserted into the crimping seat from the rear to the front side, and the crimping ring is caulked to the inside toward the crimping seat to lockingly fix the crimping ring to the crimping seat in the state of forming a step corresponding to the crimping seat in the crimping ring. Thus, the crimping seat cannot be moved backward relative to the crimping ring.
