Patent number: 9075196Abstract: An optical fiber jacket remover draws a glass fiber out from a coating by cutting the coating in a jacket removing portion and moving an optical fiber holding portion away from a jacket remover main unit in a heated state. The jacket removing portion is provided with a heater supporting member on which a heater is mounted. The heater supporting member is accommodated in a recessed receiving portion formed in a case. A heat insulating space is formed between the recessed receiving portion and the heater supporting member. A side surface of the heater supporting member and an inside surface of a lateral wall of the recessed receiving portion are brought into contact with each other via a lateral rib formed on the heater supporting member, and the heat insulating space is thereby blocked.Type: GrantFiled: November 22, 2010Date of Patent: July 7, 2015Assignees: SUMITOMO ELECTRIC INDUSTRIES, LTD., SEI Optifrontier Co., Ltd.Inventors: Toshihiko Homma, Masakazu Fukuda, Kiyoshi Nakazawa, Masahiro Hasegawa
