In other words, the third protrusion 53 so that the third protrusion 53 fitted in the groove 21 moves in a direction (downward) opposite to the recess direction (upward) of the groove 21. A space having a size larger than the allowance for fitting into the concave groove 21 is provided. That is, this space is a gap between the third protrusion 53 and the third door body 3 when the third protrusion 53 is fitted in the concave groove 21.

  The second protrusion 52 has an I-shaped cross section and contacts the upper surface of the protrusion 4. That is, the second projecting portion 52 is disposed at a position in contact with the surface of the projecting portion 4 on the concave groove 11 side in a state where the first projecting portion 51 is fitted in the concave groove 11. Yes. The second protrusion 52 has a left / right positioning portion 52a at the center in the left / right direction. The left and right positioning portions 52 a are fitted into the gap 32 of the third door body 3. The size of the gap between the lower surface of the third door body 3 and the upper surface of the protrusion 4 is larger than the height of the second protrusion 52 in the vertical direction.

  Then, the first protrusion 51 of the protection member 5 comes out of the groove 11 of the first door body 1 when the second protrusion 52 comes into contact with the upper surface of the protrusion 4. The downward movement is restricted so that there is no.

  At the same time, the third protrusion 53 of the protection member 5 comes out of the concave groove 21 of the second door body 2 when the second protrusion 52 comes into contact with the upper surface of the protrusion 4. The downward movement is restricted so that there is no.

  That is, the protection member 5 is restricted from moving in the vertical direction with respect to the refrigerator door. Moreover, the said protection member 5 is controlled by the said left-right positioning part 51a, 52a, 53a to the left-right direction with respect to the said refrigerator door.

  Thus, the protection member 5 maintains a state where it overlaps with a part of the outer surface of the first door body 1, the second door body 2, and the third door body 3. That is, the main body 50 of the protection member 5 covers at least part of the outer surfaces of the second door main body 2 and the third door main body 3 between the first door main body 1 and the protrusion 4. Since it covers and protects, all the door main bodies 1, 2, 3 can be reliably protected by the protective member 5.

  Next, a method for attaching the protective member 5 to the refrigerator door will be described.

  As shown in FIG. 5, with the first door body 1, the second door body 2, and the third door body 3 closed, the protective member 5 is placed on the refrigerator door in front of the refrigerator door. As shown in FIG. 6, the first protrusion 51 of the protection member 5 is inserted into the gap between the lower surface of the first door body 1 and the upper surface of the second door body 2. Then, the third protrusion 53 of the protection member 5 is inserted into the gap between the lower surface of the second door body 2 and the upper surface of the third door body 3.

  At this time, the distance between the lower surface of the third protrusion 53 and the lower surface of the second protrusion 52 is the distance between the upper surface of the third door body 3 and the upper surface of the protrusion 4. Therefore, the second protrusion 52 is not inserted into the gap between the lower surface of the third door body 3 and the upper surface of the protrusion 4. That is, the main body 50 is elastically deformed and bent between the third protrusion 53 and the second protrusion 52.

  Thereafter, the protective member 5 is slid upward, the first protrusion 51 is fitted into the concave groove 11 of the first door body 1, and the third protrusion 53 is moved to the second door body. 2 is fitted into the concave groove 21, and the second protrusion 52 is brought into contact with the upper surface of the protrusion 4.

Can be fitted into the groove 21 of the second door body 2. Thus, the protection member 5 can be easily attached to the second door body 2.

  Further, by fitting the left and right positioning portions 53 a of the third protrusion 53 into the gap 22 of the second door body 2, the protection member 5 is moved to the left and right with respect to the second door body 2. Positioning can be performed. Thus, it can prevent more reliably that the said protection member 5 detaches | leaves from a refrigerator.

  Further, since the protective member 5 is formed by integral molding, it is not necessary to assemble the protective member 5 before attaching the protective member 5 to the first door body 1, and the protective member 5 is used as it is. 1 can be attached to the door body 1 and workability is improved.

  Moreover, since the said protection member 5 consists of a polystyrene foam, the said protection member 5 is lightweight and can carry the said protection member 5 easily. Moreover, manufacture and a process of the said protection member 5 become easy.

  Moreover, since the said main-body part 50 has a part (upper part) extended above the said 1st projection part 51 (the dent direction of the said groove 11), the said 2nd projection part 52 is packed during packing of a refrigerator. Even if it comes to the front, the upper part of the main body 50 interferes with the first door main body 1 and the protective member 5 does not rotate around the vicinity of the first protrusion 51. Therefore, the second protrusion 52 is not separated from the upper surface of the protrusion 4, and the protection member 5 is difficult to be detached from the first door body 1.
