PURPOSE: A hinge cam for refrigerator is provided to minimize wear and friction deformation of the hinge cam by arranging a reinforcement piece made up of metallic material to the contact surface of the hinge cam. CONSTITUTION: A hinge cam(30) includes a fixation section(32) to be fixed to the lower surface of a refrigerator door or the top surface of a hinge, and a rotation support section(34) protruded upwardly from the fixation section. The fixation section has a coupling hole(32a) for fixation to the refrigerator or hinge, and the rotation support section has a hinge hole(33) for insertion of a hinge axis. The rotation support section has three protrusions(36) with inclined surfaces(36a,36b,36a',36b'), and a groove(38) formed between adjacent protrusions. The hinge cam has a contact surface consisting of protrusions, groove, inclined surfaces, and a metallic reinforcement piece(40) mounted in a groove(39) formed at the inner periphery of the hinge hole of the rotation support section.
