Abstract

PURPOSE:To improve durability and sanitation of a gasket and to ensure cooling performance and excellent appearance by a method wherein a gap between a door body and the gasket is prevented from production through prevention of deformation of the gasket due to the weight when a door is opened. CONSTITUTION:When a door body 7 is opened, a gasket tends to move in the direction of an arrow mark L due to the weight. In this case, at the upper part of the door body 7, a fin part 22A of an engaging part 22 is collided with a protrusion part 21 to block rotation of a press piece 23 in a direction opposite to a press direction, whereby the press piece 23 holds a state in contact with a flange 10A. Further, first and second fin pieces 28 and 29 and an inclination piece 30 also hold a state in contact with an inner plate 11. Meanwhile, at the lower part of the door body 7, movement of the inclination piece 30 is impeded by an expansion part 11B of the inner plate 11, and the inclination piece 30 holds a state in contact with the expansion part 11B without moving from a corner part 11A. The press piece 23 also holds a strate in contact with the flange 10A.

In a refrigerator equipped with a gasket installed between the drawing boards and a disassembly constructed by a heat insulating material filled in the space between the two plates, the said satush is provided on the inner periphery of the door body and has an opening facing outward. The gasket has a glans-shaped or arrowhead-shaped engagement portion inserted into the dovetail groove through the opening, and a pressing piece that presses against the inner circumferential surface of the outer plate. , has an inclined piece that presses against a corner of the inner plate formed by bulging inward, and
The door of the refrigerator is provided with a protrusion on one side of the dovetail groove to prevent rotation of the pressing piece in a direction opposite to the pressing direction.
