[0080] Next, a method for manufacturing the door 40 will be described. In the manufacturing process of the door 40, first, an operator assembles the upper end member 60, the lower end member 80, and the door surface material 50.

[0081] Specifically, the operator slides the upper end member 60 forward on the upper end of the door panel 50 , inserts the upper mounting surface 54 of the door panel 50 into the front groove 62 , and inserts the horizontal mounting surface 56 of the door panel 50 into the horizontal groove 63 .

[0082] The upper mounting surface 54 inserted into the front groove portion 62 is guided by the inclined portion 70a of the groove protrusion 70 and inserted between the groove protrusion 70 and the outer wall 61a. At this time, the wide area 54a of the upper mounting surface 54 is guided by the inclined portion 71a of the locking portion 71 and inserted between the groove protrusion 70 and the outer wall 61a, so that the locking portion 71 is inserted into the locked portion 57 provided in the wide area 54a.

[0083] The operator slides the lower end member 80 forward at the lower end of the door panel 50 , inserts the lower mounting surface 55 of the door panel 50 into the front groove 82 , and inserts the horizontal mounting surface 56 of the door panel 50 into the horizontal groove 83 .

[0084] The lower mounting surface 55 inserted into the front groove portion 82 is guided by the inclined portion 90a of the groove protrusion 90 and is inserted between the groove protrusion 90 and the outer wall 81a. At this time, the wide area 55a of the lower mounting surface 55 is guided by the inclined portion 91a of the locking portion 91 and is inserted between the groove protrusion 90 and the outer wall 81a, so that the locking portion 91 is inserted into the locked portion 58 provided in the wide area 55a.

[0085] When the upper end member 60 and the lower end member 80 are mounted toward the door panel 50 , the door 40 is in an assembled state, and a space with an open back side is formed by the door panel 50 and the end members 60 and 80 .

[0086] In this way, when the door 40 is assembled, the operator injects a fluid foam resin solution, such as polyurethane foam, into the interior space of the door 40 from the rear opening. The rear surface of the door 40 is then closed by the door inner panel 100. The foam resin solution expands due to foaming and flows into the interior space of the door 40, filling the interior space of the door 40 and then solidifying, thereby completing the manufacture of the door 40.

[0087] The operator also manufactures the other doors using the same process as that for the refrigerator compartment door 40. The operator then mounts the manufactured doors and various devices to the refrigerator body 11, thereby completing the manufacture of the refrigerator 10.

[0088] (8) Effect

[0089] In this embodiment, locking portions 71 and 91 are provided in the front grooves 62 and 82 of the end members 60 and 80. When the mounting surfaces 54 and 55 of the door panel 50 are inserted into the front grooves 62 and 82, the locking portions 71 and 91 are inserted into the locked portions 57 and 58 provided on the mounting surfaces 54 and 55 of the door panel 50. The operator can easily feel the locking portions 71 and 91 being inserted into the locked portions 57 and 58, making it easy to determine that the mounting surfaces 54 and 55 have been inserted into the predetermined positions of the front grooves 62 and 82. This prevents deformation, allowing the door panel 50 to be mounted on the end members 60 and 80.

[0090] In particular, when the mounting surfaces 54, 55 are further away from the front surface 51 of the door panel 50 and thus tilted outward in the vertical direction of the door, the front ends of the wide regions 54a, 55a of the mounting surfaces 54, 55 are elastically deformed to tilt inward in the vertical direction of the door until the locking portions 71, 91 are inserted into the locked portions 57, 58. Thereafter, when the locking portions 71, 91 are inserted into the locked portions 57, 58, the deformation of the wide regions 54a, 55a of the mounting surfaces 54, 55 is released and the wide regions 54a, 55a of the mounting surfaces 54, 55 are returned to their original shapes. This allows the operator to more easily feel the insertion of the locking portion 71 into the locked portion 57, thereby enabling the mounting surfaces 54, 55 to be inserted into the predetermined positions of the front grooves 62, 82.

[0091] As in the present embodiment, when the locking portions 71, 91 are provided on the outer walls 61a, 81a, the appearance of the door 40 will not be affected, and the locking portions 71, 91 protruding toward the front groove portions 62, 82 can be integrally formed together with other portions of the end parts 60, 80.

[0092] As in this embodiment, when the latched portion 57 is provided in the wide area 54a of the mounting surface 54, the strength of the mounting surface 54 can be ensured while the latched portion 57 can be provided. Furthermore, by providing the narrow area 54b having a smaller protrusion than the wide area 54a in the portion where the latched portion 57 is not provided, deformation of the front surface 51 of the door panel 50 can be suppressed by the bending process of the mounting surface 54. In addition, when the latched portion 57 is provided in the central portion in the front-to-back direction of the wide area 54a, the strength around the latched portion 57 can be easily ensured.

[0093] Similarly, when the latched portion 58 is provided in the wide region 55a of the mounting surface 55, the strength of the mounting surface 55 can be ensured while the latched portion 58 can be provided. Furthermore, by providing the narrow region 55b, which protrudes less than the wide region 55a, in the area where the latched portion 58 is not provided, deformation of the front surface 51 of the door panel 50 caused by the bending process of the mounting surface 55 can be suppressed. Furthermore, when the latched portion 58 is provided in the center of the wide region 55a in the front-to-back direction, the strength around the latched portion 58 can be easily ensured. The latched portion 58 can be provided in the center of the wide region 55a in the front-to-back direction.

[0094] As in the present embodiment, the locked portions 57, 58 are arranged in the width direction of the door 40 at positions avoiding the recesses 66 to 68, 86 to 88, 99 that are recessed inward in the vertical direction of the door, thereby easily ensuring the protrusion amount of the mounting surfaces 54, 55 at the positions where the locked portions 57, 58 are arranged.
