Therefore, it is possible to give the user of the refrigerator 1 a feeling that the shelf board 3A1 is wide, and when the article is placed on the shelf board 3A1 in the article storage area 3C1, the front door 10 is closed. However, as compared with the conventional shelf, placing the article on the P line which is the conventional article placement front end position, or up to the front position beyond the P line which is the conventional article placement front end position, It is possible to give a psychological reassurance that an article can be placed.

  The shelf 3A (shown by 3A2) on the upper side of the article storage area 3C1 has a short overhang so as not to interfere with the articles 103A and 103B stored in the door pocket 100. Further, above the door pocket 100, shelves or small pockets 106, 107 on which eggs and other small articles are placed are detachably attached by the concave and convex fitting portions formed on the left and right protruding walls 101 of the front door 10. It has been.

  Since the storage container 60 is pulled out along the side wall of the refrigerator compartment 3 on the pivot support side of the front door 10, when the front door 10 is opened and the storage container 60 is pulled forward, the storage container 60 protrudes on both the left and right sides. It is necessary to prevent the obstacle from colliding with the wall 101. For this reason, in the lower part of the door pocket 100, the height of the protruding wall 101 is reduced or eliminated. The figure shows a configuration in which the height of the protruding wall 101 is lowered, and the accessory storage unit 108 is within a range that does not protrude beyond the height of the protruding wall 101 at a position facing the storage container 60 in the lower portion of the door pocket 100. A guard 109 is attached so as to form In the illustrated embodiment, the low temperature chamber 13 is disposed on the hinge device H side, and a small chamber 46 partitioned by a partition wall 47B is provided on the right side of the hinge device H. Therefore, in the portion corresponding to the small chamber 46, the guard 109 is slightly Even if the overhang is large, it does not become an obstacle when the storage container 60 is pulled forward.
