| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a cylindrical sleeve that reduces an axial shift in connecting optical fibers and achieves stable optical fiber connection, in a cylindrical sleeve for connecting optical fibers. SOLUTION: The cylindrical sleeve for connecting optical fibers in the Claim 1 is characterized in that three cross sectionally circular arcuate small projections having equal protruding quantities inward are projectingly formed with equal spaces apart in the circumferential direction, and the three small projections protruding in the circumferential direction are arranged in four rows or more in the axial direction. Also, the Claim 2 is characterized in that, in the cylindrical sleeve for connecting optical fibers in the Claim 1, the small projections are arranged with equal spaces apart in the axial direction. The Claim 3 is characterized in that, in the cylindrical sleeve for connecting optical fibers in Claim 1 or the Claim 2, the small projections are formed in alignment in the axial direction.
