    摘要： A door opening device decreasing operational stages of a driving motor when opening a door and a refrigerator having the door opening device are disclosed. The door opening device selectively opens a first door and a second door and includes an operating member which selectively pressurizes the first door and the second door to be opened by rotation, a rotating cam including a plurality of protruding portions which contact the operating member to rotate the operating member and a plurality of depressed portions which are spaced apart from the operating member, the protruding portions and the depressed portions being formed alternately along a rotational direction of the rotating cam, a driving motor rotating the rotating cam in a forward direction and a reverse direction, and a return part returning the operating member to an initial position after at least one of the first door and the second door is opened.
