PURPOSE:To stabilize a light quantity detection output and to shorten a working time by providing plural claws which fix the distribution path of an optical fiber cable at positions where the radius of curvature of the optical fiber cable is constant. CONSTITUTION:The claws 14 formed by bending plates of brackets 4 are provided at necessary positions so that the optical fiber cable 6 is distributed while fixed between a holder 5 and a clamper 7 to the radius of curvature larger than a specific value. Only; one claw 14 is provided only inside the curvature at a curve part B nearby the clamp 7, one claw is provided at a part D as well which droops from the holder 5 and curves horizontally, and two claws 14 are arranged at the intermediate part C between B and D on both sides of the distribution path. Consequently, the optical fiber cable 6 is only hooked on those claws 14 and thus fixed to the bracket 4 along the specific distribution path so that the radius of curvature is larger than the specific value.
