ABSTRACT:
A cable or the like protection and guide device is provided in which inadvertent disconnection in a coupling portion of a side plate due to the repetition of flexional movement is avoided. A load, which is liable to occur in a flexion portion during restriction of flexional movements, is avoided, whereby excellent endurance can be obtained. Maintenance at the coupling of the side plates is easy. A cable or the like protection and guide device (100) is disclosed in which right and left spaced side plates (110, 110) are each integrally formed by a front side plate portion (111) connected to a precedent side plate (110), a rear side plate portion (111) connected to a subsequent side plate (110′) and a flexible coupling portion (113) intervened between said front side plate portion (111) and said rear side plate portion (112). Snap-fit mechanisms Sa and Sb, which connect the side plates to each other are provided between a rear side plate portion (112) of the precedent side plate (110) and a front side plate portion (111′) of a side plate (110) subsequently connected to the rear side plate portion (112).
