1. A cable protection and guide device comprising:
a number of pairs of right and left spaced side plates are articulately connected to each other in a longitudinal direction from a mounting fixed end toward a mounting movable end enabling said side plates to form a flexional circumferential bend having a flexional inner circumferential side and flexional outer circumferential side; each of said side plates includes a flexional inner circumferential side residing during bending on said flexional inner circumferential side of said bend; each of said side plates includes an outer circumferential side residing during bending on said outer flexional circumferential side of said bend;
connecting plates are detachably bridged over said flexional inner circumferential sides and said flexional outer circumferential sides of said side plates in predetermined intervals;
a cable is accommodated in a cable accommodating space surrounded by said side plates and said connecting plates along said longitudinal direction from the mounting fixed end toward the mounting movable end;
each of said side plates comprises a side plate front portion which is connected to a preceding side plate, a side plate rear portion which is connected to a subsequent side plate, and a flexible coupling portion integrally intervened between said side plate front portion and said side plate rear portion;
each of said side plates includes an outer circumferential side linear position holding mechanism and an outer circumferential side flexional position restricting mechanism at a side plate front portion on said flexional outer circumferential side; and,
each of said side plates includes an inner circumferential side flexional position restricting mechanism and an inner circumferential side linear position holding mechanism at a side plate rear portion on said flexional inner circumferential side.
