  The space component member 60 is fitted and fixed by the outer component member 52 and the space component member fitting portion 66, so that the work at the time of assembly is easy, and the number of components is reduced because the fixing member is unnecessary. It can be performed.

  The pivot support side cold air circulation suppression member 63 is formed integrally with the space component member 60, so that the assembly work becomes unnecessary and the number of assembling steps can be reduced. Also, the pivot side cold air circulation suppression member 63 is reduced. Since the shape necessary for fixing the heat exchange is not required, the shape of the heat exchange suppression space 59 can be maximized, and the heat exchange suppression effect of the heat exchange suppression space 59 can be enhanced.

  The humidity sensor 68 provided on the right side of the refrigerator compartment door 38b senses the humidity in the vicinity of the front surface of the abutment plate 51 of the partition 50, thereby determining the amount of heat of the heating plate 54 attached to the back surface of the abutment plate 51. 51 can be adjusted to an optimum state in which condensation does not occur, and power consumption can be reduced.

  As mentioned above, since the refrigerator concerning this invention can suppress the amount of heat leaks from this board and can improve the power consumption capability of a refrigerator, all the cooling equipment provided with the double door type door device which has a partition member Applicable to.
