HINGE STRUCTURE FOR REFRIGERATOR

摘要

PURPOSE: A hinge structure for refrigerator is provided to minimize wear and friction deformation by allowing lubrication oil contained in a lubrication storing groove formed at a bush member to be guided to the contact surface during slid motion of the hinge cam. CONSTITUTION: A hinge structure comprises an upper hinge cam fixed to the bottom surface of the refrigerator door and which has a coupling hole; a lower hinge cam(33) fixed onto a hinge fixed to the main body of the refrigerator, and which has a coupling hole(33) and contact the upper hinge cam; and a bush member(40) fixed to the coupling hole of the lower hinge cam and inserted into the hinge hole of the coupling hole of the upper hinge cam. The bush member has a hinge hole(41) formed at the center of the bush member for insertion of the hinge axis, and a lubrication storing groove(42) formed at the upper portion of the bush member.
