The strength of connecting portions is improved and large scale assembly of the device is possible. Side plate portions (110) each have a link module (120) with integrally molded side plates (122) of a predetermined number interconnected by coupling portions (124). Each coupling portion includes flexible coupling arms (126) extended from the coupling portions (124). Stopper links (130) each being engaged between the adjacent side plates from a cable accommodating space side and are assembled to the coupling portion by a snap-fit mechanism.

Abstract: A cable protection and guide device in which the number of parts used is reduced and assembly is simplified. Dust generation and bending fatigue is suppressed so that the cable protection and guide device exhibits excellent form stability of the cable accommodating space. Side plate portions and coupling portions are integrally molded from polyamide fatigue resistant resin into the form of a connecting link module. A polyacetal resin stopper link, which holds and limits the linear position and the bending position by engagement with the connecting link module, is inter-fitted with a coupling portion of the connecting link module by a snap-fit mechanism from the cable accommodating space side.
