A link device capable of controlling height in refrigerator doors is provided to absorb a load and noises generated due to inaccurate installation of the refrigerator doors through ball joints to realize smooth automatic returning of the doors. A hinge device(20) having automatic returning power are installed at a position separated from a rotary shaft(5) of doors(3). A support bracket(11) is fixed at a main body, wherein the rotary shaft of the door is installed. A driving link(14) has one end combined with a shaft of the hinge device to transmit automatic returning power of the hinge device when the door is closed. A driven link(13) has one end combined with the other end of the driving link rotatably, and the other end combined with the support bracket rotatably to restrict the door to return centering on the rotary shaft in accordance with automatic returning of the driving link. First and second ball joints(16,17) connect both ends of the driven link to the driving link and the support bracket rotatably, and support the rotary shaft movably. |
