Abstract: The present invention provides a refrigerator with improved refrigerator box strength and high heat insulating performance, which is configured such that external deformation due to entry of air into a vacuum heat insulating material, the entry of air being caused by aging degradation, is prevented. The present invention includes: a heat-insulated box including an inner casing and an outer casing, in which space between the inner casing and the outer casing is filled with a foamed heat insulating material; and a vacuum heat insulating material disposed in at least a side wall of the heat-insulated box together with the foamed heat insulating material, the vacuum heat insulating material including an outer skin material, the outer skin material including at least a core material and being decompression-sealed. The vacuum heat insulating material includes a gas adsorbent.

Abstract: In a refrigerator, rail devices are connected below the center of a pull-out door in a vertical direction, and connected to two ends thereof in a horizontal direction, and rail holding members are arranged on an inner casing in a heat-insulating material so as to hold both the right and left ends of the bottom of a container.

Abstract: A refrigerator (100) includes: a storage compartment formed inside of a heat-insulating main body (101) and having an opening in a front face; a pull-out door (201) which opens and closes the opening in the front face of the storage compartment; and a rail device (202) which makes a container (206) provided inside of the storage compartment movable forward and backward as the pull-out door (201) opens and closes, in which the rail device (202) includes: a fixed rail (221) fixed with respect to the storage compartment; and a movable rail (222, 223) connected to the pull-out door (201), movable forward and backward along the fixed rail (221), provided below a center of the pull-out door (201) in a vertical direction, and which supports the container (206), and the pull-out door (201) includes a supporting unit (301, 303) which supports the container (206).
