Abstract

PURPOSE: To permit repetitive bending by mounting the optical fiber provided with a protection resin layer along spiral elastic body thereby integrating these.
CONSTITUTION: The device consists of a spiral elastic body part 1, tubular elastic body 2, optical fiber 3, protection resin layer 4, spiral elastic body 5 having concave grooves and tubular body 6 having flexibility covering the outside. The optical fiber 3 held in the concave groove of the spiral elastic body 5 made of steel or the like is integrated with the spiral elastic body 5 by the tubular body 6 having flexibility and moves together with said spiral elastic body 5 and therefore no abrupt bending force is exerted to the optical fiber 3 and the breakage of the optical fiber 3 is protected. Further, it is protected by the spiral elastic body part 1 inserted into the tubular elastic body 2 made of rubber or the like and therefore, it is protected even against large compressive force.
