<p>PURPOSE:To prevent an optical fiber cable from being subjected to tensile force by installing a clamping device in which a flexible member is installed on the proper portion of a boom and inserting the optical fiber cable into the clamping device and the flexible member and clamping same. CONSTITUTION:A covered optical fiber cable (f) is put around a boom and inserted into a clamping device 12. In this case, by inserting the fiber cable (f) into a hollow body 13, a cap 14, and a rubber sleeve 16, as the cap 14 is screwed on the hollow body 13 and clamped, the rubber sleeve 16 is pressed by the end of the hollow body 13 and the inner face 15 of the cap 14 and deformed, causing the inner annular portion thereof to clamp the outer peripheral face of the optical fiber cable (f). Thereby, the optical fiber cable (f) can be externally sealed while being softly held by means of the deflected deformation of the rubber sleeve 16.</p> |
