CABLE PROTECTION AND GUIDE DEVICE

Abstract

A cable protection and guide device is disclosed which can reliably protect and guide cables without increasing and decreasing the width between link plates even if the height of the link plates of the cable protection and guide device is increased. The cable protection and guide device includes a number of link frame bodies each comprising a pair of right and left spaced link plates and upper and lower connecting rods respectively bridged on upper edge and lower edges of the link plates are connected to each other in the longitudinal direction of the device while restricting a flexion radius to a fixed value. A central connecting rod connects the pair of link plates at substantially the center portion along the height direction of the link plate. The central connecting rod is integrally molded with the pair of link plates.
