<p>PROBLEM TO BE SOLVED: To provide a connection structure between ferrules, capable of suppressing that a positional shift occurs between the ferrules.SOLUTION: In a connection structure 1 between ferrules, an inner circumferential face of a sleeve 2 is formed with a fitting protruded part 5 protruding in a radial direction, an in-circumferential face position of the ferrules 4a, 4b corresponding to the fitting protruded part 5 is formed with a fitting recessed part 6, and the fitting protruded part 5 and the fitting recessed part 6 are fitted to each other. Thereby, even if vibration is applied to the ferrules 4a, 4b inside the sleeve 2, a side face of the fitting protruded part 5 and a side face of the fitting recessed part 6 contact to restrict rotation of the ferrules 4a, 4b. Consequently, increase of transmission loss of light caused by rotation of the ferrules 4a, 4b by vibration or a change or the like of an insertion angle of the ferrules 4a, 4b relative to the sleeve 2, can be suppressed.</p> |
