There is provided an articulated cable protection and guide apparatus that can securely guide cables between a machine frame-side fixing end area and a machine movable-side moving end area without scattering abrasion powder of the articulated supporting members and the cables to the outside and that can be easily installed in the machine frame-side fixing end area and the machine movable-side moving end area. Connector units, fixed to the machine frame-side fixing end area and the machine movable-side moving end area, integrally retain articulated end portions of the articulated supporting member, cable end portions of the cables and slot end portions of the flexible belt member and seal the slot end portions of the flexible belt member.
