Similarly, the support protrusion 10d fitted into the groove 21b is also perpendicular to the back side and inclined toward the front side. Thereby, the friction between the wall surface of the groove 21b and the support protrusion 10d increases, and the case 13 cannot be easily detached from the support protrusion 10d. Further, when the case 13 is lifted up a little, the gap between the groove 21b and the support protrusion 10d becomes wider, so that sliding friction is reduced and the detachability of the case 13 is improved. The wall surface on the back side of the groove 21b may be inclined to form the wall surface on the near side vertically, or both the back side and the near side may be inclined.

  Further, the groove portion 21 b is formed to extend from the lower end of the storage portion 21 to the upper portion of the storage portion 21. For this reason, the case 13 does not easily fall off even when a stored item taken out from the lower case 15 (see FIG. 2) hits the bottom surface.

  A concave portion 10f extending downward from the bottom surface of the case 13 is formed on the back surface (the refrigerator compartment 2 side) of the door 10. Thereby, the front-end | tip of the finger hung on the bottom face of the accommodating part 21 can penetrate | invade into the recessed part 10f, the accommodating part 21 is supported deeply, the case 13 can be lifted and removed from the door 10 easily. Moreover, the upper part of the accommodating part 21 faces the upper side rather than the recessed part 10f, and approaches the back surface of the door 10. FIG. Thereby, the thickness of the door 10 can be ensured and the fall of the heat insulation effect can be prevented.

  Holes 21 f are formed in both side walls of the storage portion 21. A shaft 22c that fits into the hole 21f is provided at the tip of the arm 22a of the handle 22. The shaft portion 22c is inserted into the hole portion 21f from the outside of both side walls of the storage portion 21, and the handle 22 is rotatably supported. Thereby, the arm part 22a extended from the axial part 22c is arrange | positioned so that it may be pinched | interposed between the side wall of the accommodating part 21, and support wall 10a, 10b. Accordingly, the handle 22 can be prevented from falling off when the case 13 is attached to the door 10.

  The hole portion 21f is formed in a circular shape, and is provided with a protruding portion 21g that protrudes in the radial direction. The shaft portion 22c is formed in a circular cross section that fits into the hole portion 21f, and is provided with an engaging portion 22d that protrudes in the radial direction. When inserting the shaft portion 22c into the hole portion 21f, the engaging portion 22d is inserted through the protruding portion 21g.

The engaging portion 22d of the shaft portion 22c of the handle 22 protrudes from the shaft portion 22c in the direction in which the arm portion 22a extends. For this reason, when the left side of the handle 22 is attached to the storage portion 21, the angle formed by the arm portion 22a and the vertical direction is similarly 60 °.

  Therefore, the rotation angle of the shaft portion 22 c when the engaging portion 22 d protruding from the shaft portion 22 c is inserted into the protruding portion 21 g protruding from the hole portion 21 f is different between the left and right sides of the storage portion 21. Thereby, since the left and right ends of the handle 22 do not come off at the same rotation angle, it is possible to easily prevent the handle 22 from falling off when carrying the case 13.

  According to the present embodiment, it is movable between a first position that traverses above the opening 21a on the upper surface of the storage portion 21 and a second position that retreats from the first position and opens above the opening 21a. Since the handle 13 is provided on the case 13, the handle 22 can be held and carried when the case 13 is attached or detached.

  Thereby, when carrying stored things, such as a small foodstuff, it is not necessary to reciprocate between the refrigerator 1 and a table many times. In addition, small foods, seasonings and the like can be used while being put in the case 13 on the table. Further, since the storage portion 21 is formed deeper than the conventional rotating tray, it is possible to prevent the stored items from falling when being carried. In addition, it is not necessary to attach a handle when carrying the case 13. Therefore, the convenience of the refrigerator 1 is improved.

  Moreover, since it is only necessary to provide the handle 22 in the conventional case, the number of parts does not increase remarkably, and the portable case 13 can be obtained at low cost.

However, the shaft portion may be provided in the storage portion 21 and the handle 22 may be provided with a hole portion. Furthermore, instead of the hole portion 21f that penetrates the side wall of the storage portion 21, a non-penetrating hole portion that fits into the shaft portion 22c may be formed. At this time, the engaging portion can be engaged with a band-shaped opening formed in the peripheral wall of the hole.

  In addition, although the rotating handle 22 is attached to the storage unit 21, a sliding handle may be attached to the storage unit 21. For example, a groove extending in the front-rear direction is provided on the side wall of the storage unit 21, and the tip of the handle 22 is bent and fitted into the groove. Thereby, the handle 22 can be slid to the first position and the second position by guiding the groove.

  Moreover, although the case 13 provided in the door 10 of the refrigerator compartment 2 is demonstrated, the same effect is acquired by the same structure also about the case provided in the doors of other store rooms, such as the vegetable compartment 3 and the freezer compartment 4. be able to.
