ABSTRACT:
A cable or the like protection and guide device is disclosed in which inadvertent disconnection in a coupling portion of a side plate due to the repetition of flexional movements is avoided. Stress concentration is reduced in a flexion portion during restriction of flexional movements whereby excellent endurance on repeated flexion fatigue can be exhibited and in which the number of parts and the assembly operation can be reduced. Plates disposed in a right and left pair are integrally formed by a front side plate portion111, a rear side plate portion112, and a flexible coupling portion113interposed between the front side plate portion111and the rear side plate portion112. The coupling portion113includes a thin plate-shaped central flexion allowable region113aand base end continuous regions113b, 113bwith gradually increased plate thickness from the central flexion allowable region113aside toward the front side plate portion111and rear side portion112, respectively.
