And a fin portion 20b that extends vertically and terminates immediately before the upper surface of the vegetable compartment door 12. The blocking body 20 extends in the width direction of the lower surface 110 of the freezer compartment door 11 and is provided so as to partition the space SP between the freezer compartment door 11 and the vegetable compartment door 12 in the front-rear direction. Thereby, even when the compressor of the refrigeration cycle is OFF, it is possible to prevent the outside air from flowing into the space SP from the front direction, and the temperature of the space SP between the doors is low (for example, the upper surface of the vegetable compartment door 12). ) Can be prevented from attaching dew.

  The fin portion 20b of the blocking body 20 is made of a soft material such as soft vinyl chloride. Thus, by using a soft material such as soft vinyl chloride for the fin portion 20b, the upper surface of the blocking body 20 and the lower door (the vegetable compartment door 12 in the example of FIG. 2) is opened and closed by the door opening / closing operation. Even when touching, the top surface of the door is hardly damaged. As a drawer-type door, a drawer-type door having a step for self-closing when the door is closed and rising upward by several mm (for example, 2 mm) when the door is opened and closed is known. Even when such a drawer-type door is used as the vegetable compartment door 12, the opening / closing operation can be made smooth by configuring the fin portion 20b with a soft material.

  Then, the attachment structure of the interruption | blocking body 20 in this Embodiment is demonstrated with reference to FIG. FIG. 3 is a perspective view showing a mounting structure of the blocking body 20.
