  In the figure, the refrigerator body 1 is divided into a plurality of storage chambers by partition members 2, 3 and 4, the refrigerator main body 1 is divided into a plurality of storage chambers, the uppermost portion is a drawer type ice making chamber 6, a switching chamber 7, and a freezer. There are a room 8 and a vegetable room 9. Each of the chambers is provided with a door, and the door of the refrigerator compartment 5 is a double door with a rotary first door 11A and a second door 11B. The doors 12, 13, 14, and 15 of the ice making chamber 6, the switching chamber 7, the freezing chamber 8, and the vegetable chamber 9 are drawer type doors.

  As shown in FIGS. 3 and 5, the first door 11 </ b> A and the second door 11 </ b> B serving as the kannon-type doors of the refrigerator compartment 5 are either one of the first door 11 </ b> A on the left side in this example, as shown in FIG. A body 16 is provided, and is configured to keep tightly attached to the magnetic packing 17 provided on the inner periphery of the first door 11A and the second door 11B when the door is closed to keep the refrigerator compartment 5 airtight. . The magnet packing 17 is a bag-like packing containing magnets 17A and 17B, as is well known.

As shown in FIG. 5, the upper and lower parts of the rotary partition 16 are pivotally supported by the hinge member 18 on the end of the first door 11 </ b> A. And a heat insulating material 22 is provided in the inner space, and a reversing spring 23 made of a coil spring is suspended between the hinge member 18 attached to the first door 11A. As a result, when the first door 11A is closed, the rotary partition 16 is urged in a direction in close contact with the magnet packing 17 provided on the inner periphery of the first door 11A and the second door 11B. When the door 11A is opened, it is biased toward the inside of the first door 11A, that is, the shelf side wall surface 21 side.

  The front plate 19 of the rotary partition 16 is made of a magnetic metal and is attracted to the magnets 17A and 17B of the magnet packing 17.

  The magnetic force of the magnets 17A and 17B of the magnet packing 17 is the magnetic force of the magnet 17A on the side of the first door 11A provided with the rotating partition 16, and the second, ie, the rotating partition 16 is not provided. It is set to be smaller than the magnetic force of the magnet 17B on the door 11B side.

  That is, the adhesion between the first door 11A on the side where the rotating partition 16 is provided and the rotating partition 16 is such that the second door 11B on the side where the rotating partition 16 is not provided and the rotating partition 16 are in close contact.
