Abstract
To make a door lightweight by a method wherein a hollow reinforced part is an integral part of an end piece and is formed on the heat-insulating material side and along almost the whole length. An end piece 5 overlaps a flange 12 of the door inner plate 4, and an end flange 3 of a door outer plate 2 is fitted in a connecting groove 6 of the end piece 5. The fitting direction of the door outer plate 2 in the end piece 5 is almost the same as the direction of the depth of a door. An easily- deformable place (reinforced part 8) of the end piece 5 has a double-wall construction and a surface 5a of the end piece 5 is prevented from directly receiving heat and foaming pressure when foam insulation is filled. The hollow part inside the reinforced part 8 is forcibly formed by blowing gas into the hollow part during injection molding. Thereby, the weight can be reduced and an inexpensive door for a refrigerator can be obtained.
