| 1. A refrigerator comprising:
a body having a cooling chamber;
a basket received in the cooling chamber and having a door at a front side thereof;
a pair of lifting rails connected to the door;
a lifting frame movably connected to each of the pair of lifting rails, and on which the basket is positioned;
a pair of driving arms, each driving arm being provided with a roller roll-motioned at a lower surface of the lifting frame
at one end thereof, the pair of driving arms being connected by a hinge shaft extending therebetween, the hinge shaft being
rotatably mounted at the door; and
a driving unit mounted at the door to rotate the pair of driving arms; and
a locking unit for locking the pair of driving arms when the lifting frame is lifted and thereby for maintaining a lifted
position of the basket,
wherein the locking unit is a locking protrusion formed at a lower surface of the lifting frame for stopping the roller roll-motioned
at the lower surface of the lifting frame when the lifting frame is lifted to the maximum, and
wherein a distance between connections of the lifting frame to the pair of lifting rails measured in a lateral direction of
the door is greater than a distance between the pair of driving arms measured in the lateral direction of the door.
