Abstract: Disclosed are a guide rail for allowing a drawer to be smoothly opened and closed, and a storage apparatus and a refrigerator having the same. The refrigerator includes a drawer accommodating room; a drawer accommodated in the drawer accommodating room; and a rail configured to guide the drawer to be pulled out of or pushed into the drawer accommodating room. The rail includes a first member extended along pulling-out or pushing-in directions of the drawer and supporting the drawer; a second member extended corresponding to the first member and supported in the drawer accommodating room of the refrigerator; and a plurality of rolling elements arranged between the first member and the second member and being in rolling-contact with the first member and the second member when the drawer is pulled out or pushed in. The second member includes a load support surface having an inward height difference as much as a predetermined gap from a rolling contact surface with which at least one second rolling element different from a first rolling element among the plurality of rolling elements is in rolling-contact so that at least one of the first rolling elements among the plurality of rolling elements is in contact with the first member and the second member and support a load of the drawer in a state that the drawer is positioned in at least one of a critical pull-out section or a critical push-in section. Thus, the refrigerator equally maintains a degree of contact between the rolling element and the members while the guide rail works, thereby uniformizing the operation quality of the guide rail.
