Door for refrigerator

Abstract

An outer door of a door for a refrigerator according to the present invention has a front portion defining a front surface, and first and second side portions defining side surfaces of the door by being bent rearward from both lateral sides of the front portion. A door bracket made of synthetic resin is connected to a rear end of the second side portion to define a part of one of the side surfaces. A door liner defining a rear surface of the door is fixed to a rear end of the first side portion and to a rear end of the door bracket. An inner frame for supporting the both side surfaces of the door upon contraction of a foaming liquid injected into the interior of the door comprises a first supporting portion that is in close contact with an inner surface of the first side portion, a second supporting portion that is in close contact with an inner side of the door bracket, and a supporting bar for connecting and supporting the first and second supporting portions.
