Abstract
Disclosed is a refrigerator that has a slider and chain units that are coupled in a manner that allows rotation. The slider and chain units define a cable chain that covers a wire. Curve guide portions are positioned between the slider and a chain unit, and a rotation restricting portion is positioned between the chain units. The cable chain may curve in the same direction regardless of the force applied so as to reduce potential damage on the wire due to scratches by peripheral components and mis-operation of a refrigerator door. Also, a buffer may be installed at an end of a fixed rail to provide additional safety, a protection cover is installed at a driving motor to reduce potential for separation of the wire, and a door switch is installed at a rail guide to facilitate detachment of the door switch.
