ABSTRACT:
To provide a cable or the like protection and guide device, which reliably maintains linear position mode of the adjacent connecting link bodies without backlash to remove distortion and can attain a smooth change of form between the linear position mode and the bending position mode, and also can exert endurance due to the connecting pin and the pin connecting hole for a long period of time. A position limiting concave portion110aof a side plate110, which connects link bodies100on the front and rear sides of a cable or the like protection and guide device100includes a pair of abutting surfaces111, 111disposed in parallel with a reference line passing through bending center points of connecting pins130disposed on the front and rear sides of the link body100, and a position limiting convex portion110bof the side plate110includes a pair of linear position limiting surfaces112, 112disposed in parallel with each other in a plane symmetry with respect to the bending center point. Accordingly, bending of the linear position mode can be removed.
