PROBLEM TO BE SOLVED: To prevent deformation of a gasket mounting frame, by preventing forming polyurethane from filling inside a gap between the gasket mounting frame and a back plate of a door of a refrigerator where foaming polyurethane is injected into the inside thereof for forming a heat insulating layer. SOLUTION: The mounting frame takes an overall shape formed by connecting a part with an U-shaped section 8 and a part with an L-shaped section 12, an end edge of upper and lower sides 9 and 10 of the U-shaped part is so bent as to face each other, the end edge thereof is sloped to form a dovetail 13, both ends of an upper side 9 is slightly extended, and a neck 14 is provided on the opening side of the U-shaped part 9 at the upper corner part of a longitudinal piece 11. Further, around the upper side 9 of the U-shaped part 8, a recessed groove 15 where a back side inner periphery edge 3 of a front plate 2 is fitted in is provided, and a fin 17 made of soft vinyl chloride is provided for converging both surfaces with decline toward diagonally backward (back plate side) from the lower end of a longitudinal side 16 of the L- shaped section 12.
