摘要： PROBLEM TO BE SOLVED: To provide an optical closure by which excellent drip-proof performance is obtained and by which reduction in cost is possible. SOLUTION: The optical closure is equipped with a closure sleeve and a sealing member 31 installed at the end of this closure sleeve. On the inner face of a cable introducing hole 35a of the sealing member 31, there are formed an outer seal wall 37A and an inner rib 38A. The outer seal wall 37A can seal the cable introducing hole 35a when no optical fiber cable is inserted and can deform to come in contact with the outer face of the optical fiber cable to seal the cable introducing hole 35a when the optical fiber cable is inserted. The inner rib 38A can come in contact with the outer face of the optical fiber cable to seal the cable introducing hole 35a. The outer diameter of the optical fiber cable by which the inner rib 38A can seal the cable introducing hole 35a is larger than the outer diameter of the optical fiber cable by which the outer seal wall 37A can seal the cable introducing hole 35a.
