  In FIG. 3, the right door 46 and the left door 47 are in a closed state, but at this time, the right-handed spring 27 and the left-handed spring 28 are slightly narrower than the natural angle. Therefore, the right partition 23 and the left partition 24 receive a force in a direction in which they are pressed against each other. And since the film-like right packing 29 and the film-like left packing 30 are compressed by this force, they are in an excellent state of sealing when the door is closed. In this case, a magnetic body is provided in an opposing portion of either the right partition 23 or the left partition 24, or a magnetic body is provided in one partition (for example, the right partition 23), and the other partition 24 is steel. By providing the sheet metal, the sealing performance can be further improved.

Due to the action of the right-handed spring 27 and the action of the right groove portion 23a correcting the position of the right guide shaft 25c, the right partition 23 is in contact with the right gasket 56 in a state where the right door 46 is closed.

The surface 53a is locked at the substantially maximum extension portion position. Therefore, when the doors 46 and 47 are closed, the air heat insulation layer formed by the film-like left packing 30 and the film-like right packing 29 has a substantially maximum thickness, so that the amount of heat leakage from the refrigerator compartment 2 is small. It becomes a refrigerator, and thus power consumption is reduced. Further, it is not necessary to provide a heating means such as a dew proof heater, so that the cost is low.

Next, the operation will be described.
As shown in FIG. 4, when the left door 47 is opened in the direction B, the left partition 24 moves to the left because the left guide groove 24b provided on the upper surface of the left partition 24 moves along the left guide pin 109a. Slide in the direction of the door inner plate 54. Since the left-handed spring 28 has a neutral point, when the left-handed spring 28 passes through the neutral point in accordance with the operation of the left partition 24, the direction in which the left partition 24 is pulled toward the left door inner plate 54 side. To generate elastic force.
For this reason, the left partition 24 does not interfere with components on the right door 46 side in the locus accompanying the rotation of the left door 47. Since the film-like packing 30 is made of a soft material, it can be deformed along with the operation of the left partition 24, and the operation of the left partition 24 is not hindered.

When the left partition 24 slides, the left partition 24 is provided with a left groove 24a that inclines toward the inner side of the refrigerator compartment 2 toward the left door inner plate 54 side. As the left door 47 opens in the direction B, the left door 47 moves away from the left door gasket 57.
For this reason, the left partition body 24 is not rubbed against the left door gasket 57 with the operation of the left door 47, the deterioration of the left door gasket 57 over time can be suppressed, and the quality is excellent. Note that the right door 46 operates in the same manner as the left door 47.
