PURPOSE:To assure the curvature above the min. radius of curvature required without being affected by the increase or decrease in the number of holding of optical cords by forming a 1st holding member and 2nd holding member which pinch and hold the optical cords in such a manner that these members can move in the direction orthogonal with the introducing direction of the optical cords according to the number of the optical cords to be introduced. CONSTITUTION:Bent pieces 7 of the 2nd holding member 6 are built into guide grooves 3 of the 1st holding member 1. The 1st holding member 1 and the 2nd holding member 6 are movable in the direction Y orthogonal with the introducing direction X of the optical cords 11 and 12 according to the number of the optical cords 11 and 12 to be introduced and pinch and hold the optical cords 11 and 12. Screws 17 are screwed into screw holes 9 of the 2nd holding member 6 and the front ends thereof are pressed to perpendicular pieces 2 of the 1st holding member 1. A curved surface 78 for contact with the optical cords constitutes the curved surface above the min. radius of curvature required from the optical characteristics of the optical cords 11, 12. The curvature above the min. radius of curvature required from the optical characteristics is assured without being affected by the increase or decrease of the number of the cords by adjusting the number of holding of the optical cords 11, 12. |
