To provide an inexpensive cable accommodation mechanism which requires no expensive cable winch to wind or unwind a cable or no sophisticated and expensive control device to allow the rotation of a cable winch to follow the movement of the cable, or requires no power.

One end part of this cable accommodation mechanism is connected to a mobile object moving in the vertical direction, and moved together with the mobile object, and a protective support is provided along the cable. The protective support is formed by combining a plurality of bending means comprising a plurality of links and a plurality of non-bendable plates with each other, and the cable is held by the plates.
