PURPOSE:To prevent an increase of a transmission loss due to the fact that an optical fiber is bent excessively, by fitting a connector base having a holder by which an optical fiber connector can be inserted and drawn out freely, to a connecting box, so that the direction of the holder can be switched freely to the front and the side of the connecting box. CONSTITUTION:A connector base 7 is constituted so that a holder 15 of the connector base 7 is directed to the front or the side of a connecting box 2, by making a rotary shaft 17 freely rotatable around a rotary shaft 17, and replacing hinges 18, 19 to the connecting box 2. Therefore, even if an optical fiber 5 is wound and bent in the wide width direction of width of the connector base 7 and its radius is taken large, when an optical fiber connector 28 is inserted into the holder 15 or the connector 28 is drawn out, the inserting or drawing-out work can be executed easily by directing the holder 15 to the front of the connecting box 2. |
