A home appliance comprising a drawer rail configured to withdraw an item accommodation unit provided in a storage chamber, wherein the drawer rail comprises: a first rail mounted to the storage chamber; a second rail coupled to the item accommodation unit; a third rail disposed between the first rail and the second rail; a first retainer disposed between the first rail and the third rail to allow relative sliding movement; a second retainer disposed between the second rail and the third rail to allow relative sliding movement; a first stopper (216, 545) for limiting an allowable relative sliding distance between the first rail and the third rail, the first stopper (216, 545) comprising a stopper flange being disposed at a position further inward than a distal end of the first rail and a stopper protrusion being disposed at a position further inward than a distal end of the first retainer; and a second stopper (316, 545) for limiting an allowable relative sliding distance between the second rail and the third rail, the second stopper (316, 545) comprising a stopper flange being disposed at a position further inward than a distal end of the second rail and a stopper protrusion being disposed at a position further inward than a distal end of the second retainer, wherein the first rail and the second rail each comprise vertical surfaces (210, 310) and bent surfaces (220, 320) bent laterally from upper ends and lower ends of the vertical surfaces (210, 310), wherein the vertical surfaces (210, 310) have therein a plurality of perforated portions (211, 311), and the first rail and the second rail are preferably formed so as to have a same size, a same shape and same perforated portions (211, 311) as each other, wherein the perforated portions (211, 311) comprise bending-perforated portions for a bending process, and the stopper flanges (216, 316) are formed by bending portions of the vertical surfaces (220, 320) through the bending-perforated portions formed in the first rail and the second rail, and wherein the bending-perforated portions are located at positions further inward than outermost perforated portions (211, 311). a first rail mounted to the storage chamber; a second rail coupled to the item accommodation unit; a third rail disposed between the first rail and the second rail; a first retainer disposed between the first rail and the third rail to allow relative sliding movement; a second retainer disposed between the second rail and the third rail to allow relative sliding movement; a first stopper (216, 545) for limiting an allowable relative sliding distance between the first rail and the third rail, the first stopper (216, 545) comprising a stopper flange being disposed at a position further inward than a distal end of the first rail and a stopper protrusion being disposed at a position further inward than a distal end of the first retainer; and a second stopper (316, 545) for limiting an allowable relative sliding distance between the second rail and the third rail, the second stopper (316, 545) comprising a stopper flange being disposed at a position further inward than a distal end of the second rail and a stopper protrusion being disposed at a position further inward than a distal end of the second retainer, wherein the first rail and the second rail each comprise vertical surfaces (210, 310) and bent surfaces (220, 320) bent laterally from upper ends and lower ends of the vertical surfaces (210, 310), wherein the vertical surfaces (210, 310) have therein a plurality of perforated portions (211, 311), and the first rail and the second rail are preferably formed so as to have a same size, a same shape and same perforated portions (211, 311) as each other, wherein the perforated portions (211, 311) comprise bending-perforated portions for a bending process, and the stopper flanges (216, 316) are formed by bending portions of the vertical surfaces (220, 320) through the bending-perforated portions formed in the first rail and the second rail, and wherein the bending-perforated portions are located at positions further inward than outermost perforated portions (211, 311).
