The wall 20 can be easily installed. For this reason, the manufacturing man-hour of the refrigerator 1 can be reduced.

  Further, a seal member 53 is disposed between the inclined surface 40a and the inclined surface 37c. Thereby, even if the lower end of the fitting part 40 shifts upward with respect to the groove part 37 due to the processing accuracy of the partition wall 20, the gap between the fitting part 40 and the groove part 37 can be sealed by the inclined seal member 53.

  In addition, since the axial direction of the screw 41 is substantially orthogonal to the inclined surface 40a, the gap between the inclined surface 37c and the inclined surface 40a can be reliably sealed by tightening the screw 41.

  Further, the locking surface 43a is formed by an inclined surface, and the partition wall 20 has an abutting portion 44 made of an inclined surface facing the engaging surface 43a, and between the locking surface 43a and the abutting portion 44. Since the sealing member 39 is arranged, the sealing property between the vegetable compartment 5 and the freezing compartment 21 can be further improved, and the cooling efficiency of the refrigerator 1 can be improved.

  Further, a seal member 39 is disposed between the inclined locking surface 43 a and the contact portion 44. Accordingly, the gap between the contact portion 44 and the stepped portion 43 is sealed by the inclined seal member 39 even if the contact portion 44 is displaced upward with respect to the stepped portion 43 due to the processing accuracy of the partition wall 20. Thereby, the cooling efficiency of the refrigerator 1 can be improved.

  In addition, the vegetable compartment 5 (first storage compartment) is maintained at the refrigeration temperature, and the freezing compartment 21 (second storage compartment) partitioned from the vegetable compartment 5 by the partition wall 20 is maintained at the freezing temperature. For this reason, between the vegetable compartment 5 and the freezer compartment 21 can be sealed by the seal member 39 and the seal member 53, and intrusion of cold air having different temperatures can be prevented. Therefore, the cooling efficiency of the refrigerator 1 can be improved.

  Further, the heat radiating pipe 52 disposed on the front surface of the partition wall 20 can be disposed in the groove portion 37 before the partition wall 20 is installed. Therefore, damage to the heat radiating pipe 52 before the partition wall 20 is installed can be prevented.
