<p>An optical fiber length adjuster (11) has: an inlet (15) and an outlet (16) for an optical fiber (9); and a holding section (14) that holds the optical fiber (9) in a state wherein the optical fiber (9) is deformed. The holding section (14) is configured to reduce the length of the holding optical fiber (9) in the cases where a tensile force applied to the optical fiber (9) is increased, and to increase the length of the holding optical fiber (9) in the cases where the tensile force applied to the optical fiber (9) is reduced.</p> |
