A refrigerator door equipped with hinge is provided to improve the durability by preventing a damage of a refrigerator door from noises and shocks by a dead load of the refrigerator door in a case of a free fall. In a refrigerator door equipped with hinge, a hollowed type of a housing(30a) opens one side to have a receiving room at an indoor. A hinge axis(38) transfers an outer rotation force to an opened side of the housing. A spring(35) generates an elastic repulsive power to an inner part of a closed side of the housing. A driving cam(37) having a section is connected to the hinge axis and includes a first slope region(37a) having a predetermined slope and a second slope region(36b) having a slope being slighter than the slope of the first slope region. And, a secondary cam is located between the driving cam and the spring and is connected to a cross-section of the driving cam with being mutually in contact with each other by having the same surface. |
