Abstract:
1. A fixing tool for fixing a fiber holding member to an optical fiber, comprising: a tool body for receiving the optical fiber and the fiber holding member to dispose the fiber holding member on a first specific part of the optical fiber; and a positioning device for fixing a second specific part of the optical fiber to the tool body in the state where the optical fiber and the fiber holding member are received in the tool body, the second specific part being a portion between the first specific part and a longitudinal end face of the optical fiber, wherein the tool body has: a principal groove extending in a predetermined direction to receive the optical fiber and the fiber holding member; a contacting portion facing the principal groove in the predetermined direction to be kept in contact with the longitudinal end face of the optical fiber received in the principal groove; and an engaging portion formed in the principal groove so as to be engaged with the fiber holding member in the predetermined direction to inhibit movement of the fiber holding member towards the contacting portion, and wherein the positioning device comprises: a base member fixed to the tool body and having a receiving surface for receiving the second specific part; and a pressing member for pressing the second specific part to the base member, whereby the base member positions the optical fiber relative to the tool body in the predetermined direction in a state where the optical fiber is received in the principal groove.
