1 to 6, the storage basket 200 of the refrigerator according to the embodiment of the present invention has a storage space 210 for storing food. The top surface of the storage basket 200 is open, and may withdraw food into the storage space 210 through the open top surface. In addition, the storage basket 200 has a front wall 220, a rear wall 230, both sidewalls 250, and a bottom wall 240.

In particular, both sidewalls 250 of the storage basket 200 may have a lower first wall 260 and a second wall 270 projecting outwardly relative to the first wall 260, as shown in FIG. 4. And a coupling wall 281 that connects the first wall 260 and the second wall 270 and is formed substantially horizontally. Here, the vertical length L1 of the first wall 260 is smaller than the vertical length L2 of the second wall 270. Rail portions 310 and 320 of the support frame 300 may be disposed between the first wall 260 and the inner box 20.

With the above structure, the storage basket 200 of the refrigerator according to the embodiment of the present invention has a wider storage space 210 than the storage basket having a conventional flat sidewall.

On the other hand, the storage basket 200 is a support frame by placing a coupling wall 280 formed between the first wall 260 and the second wall 270 on the storage basket support surface 451 of the support frame 300. 300 may be supported.

Here, a coupling protrusion 281 protruding downward is formed in the coupling wall 280 of the storage basket 200, and a coupling hole 452 in which the coupling protrusion 281 may be inserted is formed in the support frame 300. Can be. Accordingly, the coupling protrusion 281 may be inserted into the coupling hole 252 to fix the storage basket 200 to the support frame 300.

On the other hand, the upper end of the storage basket 200, the roller support surface 290, the first roller 401 of the auxiliary basket 400 is supported, and the front projection protruding upward from the front end of the roller support surface 290 ( 291, a rear projection 293 protruding upward from the rear end of the roller support surface 290, and an upward projection between the front projection 291 and the rear projection 293 of the roller support surface 290. The auxiliary protrusion 292 and the second roller 290 may be formed in contact with the rear surface of the auxiliary basket 400 in a rolling motion.

The front protrusion 291 may serve as a front stopper that limits the relative position of the auxiliary basket 400 to the front relative to the storage basket 200, and the rear protrusion 293 conversely stores the auxiliary basket 400. It may serve as a rear stopper to limit the relative position to the rear with respect to the basket 200. Accordingly, the front protrusion 291 and the rear protrusion 293 are preferably formed to have a predetermined height that the first roller 401 cannot ride over.

If the force is not directly applied to the auxiliary basket 400 in the state, the auxiliary basket 400 may not move relative to the storage basket 200.

Accordingly, when the storage basket 200 is pulled out while the first roller 401 is accommodated in the roller accommodating portion 296, the auxiliary protrusion 292 presses the first roller 401 and the auxiliary basket 400 is stored. It may be withdrawn with the basket 200.

Of course, as described above, when the storage basket 200 is introduced in the state in which the first roller 401 is accommodated in the roller accommodating portion 296, the front protrusion 291 presses the first roller 401 to support the auxiliary basket 400. It may be retracted with this storage basket 200.

On the other hand, the auxiliary protrusion 292 may be formed at a somewhat lower height than the front protrusion 291 and the rear protrusion 293 so that the first roller 401 can ride over the auxiliary protrusion (292).

Therefore, when the first roller 401 is applied to the auxiliary basket 400 by directly applying a force to the auxiliary basket 400 in a state in which the first roller 401 is accommodated in the roller accommodating portion 296, the first roller 401 is the auxiliary protrusion 292. Only the auxiliary basket 400 may be introduced without moving the storage basket 200 without moving.

On the other hand, the support frame 300 has a rear rail portion 310 and the right rail portion 320 coupled to the inner box 20, and the rear end connecting the left end of the left rail portion 310 and the right rail portion 320, respectively.
