The invention relates to a refrigerator. The invention aims at providing a refrigerator characterized by providing a decompression chamber formed by resin, improving rigidity, expanding width, and increasing inner volume. An external contour part (14) is made to a resin forming member divided into upper and lower two parts and a sealing structure with mutual maintenance of air impermeability. The internal of the external contour part can not be limited to the shape of a taper from the opening, and is further made to a dome shape protruding to the external side for ensuring strength. Via making a dividing surface (142a) incline from the surrounding of the rear part at the upper part of the opening (140r), and in a mode of gradually reducing toward the rear part to become a plane of a rear surface wall (140d) connecting a roughly central part of the rear surface wall of the external contour part (14), thereby preventing an upper housing (141) from forming a thin plate shape to ensure thickness (141t) and strength. Since the dividing surface (142a) is an inclined plane, therefore, precision is easily reached, and air impermeability is easily maintained. |
