May be good. Further, the locking portion 430 is not limited to the tip of the shaft portion 440, but is at least at a position where it can be locked to the bottom surface portion 240 around the notch 253, and is spaced from the partition portion main body 410 or the support portion 420. It suffices if it is provided at the above position. When the partition portion main body 410 can be supported only by the locking portion 430, the partition member 400 does not have to have the support portion 420.

Next, the dimensional relationship of each member will be described with reference to FIGS. 4 and 5. The diameter of the shaft portion 440 is smaller than the width L2 in the lateral direction of the insertion hole 251 of the door pocket 200, the width L3 in the lateral direction of the locking portion 430, and the width L5 in the lateral direction of the notch 253. However, in order to restrict an unintended slide of the partition member 400, a restricting portion 253a may be provided in which the width in the lateral direction in a part of the notch 253 is narrower than the diameter of the shaft portion 440. Specifically, a restricting portion 253a may be provided in which the width L5a in the lateral direction of the notch 253 immediately before reaching the mounting hole 252 from the insertion hole 251 is set to a width L5a narrower than the diameter of the shaft portion 440. Further, the width L3 of the locking portion 430 in the lateral direction is narrower than the width L2 of the insertion hole 251 in the lateral direction. Further, the longitudinal width L4 of the locking portion 430 is narrower than the longitudinal width L1 of the insertion hole 251 and wider than the lateral width L2 of the insertion hole 251 and the lateral width of the notch 253. Wider than L5. That is, the locking portion 430 and the shaft portion 440 of the partition member 400 and the hole portion 250 of the door pocket 200 are arranged so that the dimensional relationship is L1> L4> L2> L3> L5> the diameter of the shaft portion 440> L5a. It is configured.

Next, a method of attaching the partition member 400 to the door pocket 200 will be described.
First, the locking portion 430 of the partition member 400 is inserted into the hole portion 250 from the side where the stored items of the door pocket 200 are stored, that is, the upper surface side of the bottom surface portion 240. Then, the locking portion 430 is slid into the notch 253 and locked to the bottom surface portion 240 around the notch 253 (mounting hole 252). In this way, the partition member 400 is attached to the door pocket 200 with the bottom surface portion 240 of the door pocket 200 sandwiched between the support portion 420 and the locking portion 430 of the partition member 400. With such a configuration, the partition member 400 can be attached to the door pocket 200 without the support portion 420 and / or the locking portion 430, even if a load is applied from the stored object. It becomes difficult to come off from the door pocket 200.

By the way, the upper surface of the bottom surface portion 240 of the door pocket 200 has a planar shape at least within the range in which the partition member 400 can be attached. Further, the lower surface of the support portion 420 of the partition member 400 has a planar shape. Therefore, when the partition member 400 is attached to the door pocket 200, the bottom surface portion 240 of the door pocket 200 and the support portion 420 of the partition member 400 come into contact with each other, and a gap is unlikely to occur between them. Therefore, since it is difficult for dust and dirt to enter between the support portion 420 and the bottom surface portion 240, the usability of the refrigerator 100 can be improved, for example, the inside of the door pocket 200 can be easily cleaned.

Next, a method of removing the partition member 400 from the door pocket 200 will be described.

Then, the locking portion 430 is moved toward the upper surface side (vertical direction) of the bottom surface portion 240 and pulled out from the insertion hole 251. In this way, the partition member 400 can be removed from the door pocket 200 only by moving it in the horizontal direction and the vertical direction. Therefore, even if a load from the stored object is applied to the partition member 400, it is applied from the horizontal direction of the partition member 400, not from the vertical direction of the partition member 400. The partition member 400 is difficult to move in the vertical direction of the partition member 400 and is difficult to come off from the door pocket 200. Further, the refrigerator 100 can improve the usability of the refrigerator 100, for example, the inside of the door pocket 200 can be easily cleaned as compared with the case where the partition member 400 cannot be removed from the door pocket 200.

Next, a method of adjusting the position where the partition member 400 is provided will be described.
FIG. 6 is a diagram showing an example in which the position where the partition member 400 is provided is adjusted. As shown in FIG. 6, three notches 253 are formed in the bottom surface portion 240 of the door pocket 200. The shaft portion 440 of the partition member 400 passes through any of the plurality of notches 253 and moves to the mounting hole 252. Therefore, as shown in FIGS. 6A, 6B, and 6C, the position where the partition member 400 is provided can be adjusted according to the position of the notch 253 through which the shaft portion 440 of the partition member 400 passes. With such a configuration, the position where the partition member 400 is provided can be adjusted according to the size of the stored items to be stored in the door pocket 200, the storability of the door pocket 200 is improved, and the usability of the refrigerator 100 is improved. Can be improved.

Further, even when adjusting the position where the partition member 400 is provided, it is only necessary to move the partition member 400 in the horizontal direction, and it is not necessary to move the partition member 400 in the vertical direction. Therefore, even when the stored items are stored in the door pocket 200, the position where the partition member 400 is provided can be adjusted without taking out the stored items from the door pocket 200, which improves the usability of the refrigerator 100. be able to.

By the way, when the partition member 400 is locked along the second direction in which the notch 253 extends (that is, the direction in which the notch 253 extends and the longitudinal direction of the partition member 400 are substantially the same directional components. The partition member 400 is removed from the door pocket 200 by sliding in the longitudinal direction of the partition member 400. When such a configuration is adopted, even if a load from the stored object is applied to the partition member 400, it is applied from the lateral direction of the partition member 400 and is applied in the longitudinal direction of the partition member 400. It is not added from. Therefore, even if a load from the stored object is applied, the partition member 400 is difficult to slide in the longitudinal direction of the partition member 400, so that it is difficult to come off from the door pocket 200.

According to the present embodiment, the position of partitioning the space in the door pocket 200 provided in the storage chamber of the refrigerator 100 can be adjusted, and the partition member 400 which is hard to come off due to the load from the stored items stored in the door pocket 200 can be provided. Since the provided refrigerator can be provided, the usability of the refrigerator 100 can be improved.
