<Effect in Embodiment 1>
As described above, in the refrigerator 100 of Embodiment 1, the fixing sheet metal 16 for attaching the guide portion 14 is arranged in the space between the outer case 11 and the inner case 12. does not reduce the storage capacity of At this time, in the space between the outer box 11 and the inner box 12, in addition to the foamed heat insulating material 18, the vacuum heat insulating material 17 is arranged. The fixing sheet metal 16 has a U-shape, and a pair of fixing holes 16a are formed on one surface 161 in contact with the inner box 12, and a pair of convex surfaces 16b are formed on the other surface 162 at positions facing the fixing holes 16a. is formed. In the fixing sheet metal 16, since the tip of the guide fixing screw 15 can be covered with the convex surface 16b, the guide fixing screw 15 does not come into contact with the vacuum heat insulating material 17. can be prevented from being damaged. That is, it is possible to prevent the guide fixing screw 15 from contacting the vacuum heat insulating material 17 and causing the vacuum heat insulating material 17 to break and become a defective product. In addition, by providing the fixing sheet metal 16 with a convex surface 16b having a flat projecting surface rather than a sharp protrusion, the vacuum heat insulating material 17 is not damaged even when it comes into contact with the vacuum heat insulating material 17.例文帳に追加In particular, by providing the convex surface 16 b having a flat projecting surface, the vacuum heat insulating material 17 is prevented from touching the edge 163 of the fixing sheet metal 16 , and the fixing sheet metal 16 damages the vacuum heat insulating material 17 . can be suppressed. Thus, according to the refrigerator 100 of Embodiment 1, contact between the tips of the guide fixing screws 15 and the vacuum heat insulating material 17 can be avoided without reducing the storage capacity.

Here, conventionally, a reinforcing plate for fixing the screw to the inner box and an adhesive for fixing the reinforcing plate are used, and the tip of the screw and the vacuum insulation material are used to protect the vacuum insulation material. Measures such as providing a soft sheet between the material and the material were devised. However, in this case, there is a problem that the number of parts increases due to additional parts such as a soft sheet in addition to the reinforcing plate, and the number of man-hours in the assembly work also increases.

In contrast, the refrigerator 100 of the first embodiment does not require the conventional adhesive for fixing the reinforcing plate and the soft sheet for protecting the vacuum heat insulating material 17. There is no increase in man-hours for assembly work.

Furthermore, in the refrigerator 100 of Embodiment 1, the fixing sheet metal 16 has the convex surface 16b formed in a range wider than the size of the fixing hole 16a including the area facing the fixing hole 16a. Further, according to the refrigerator 100, in the fixing sheet metal 16, the convex surface 16b is arranged on the extension line of the fixing hole 16a. With such a configuration, even when the guide fixing screw 15 is screwed in at an angle, the guide fixing screw 15 is accommodated within the convex surface 16b, and the tip of the guide fixing screw 15 is securely attached to the convex surface 16b. covered. Therefore, it is possible to prevent the tip portion of the guide fixing screw 15 from damaging the exterior material of the vacuum heat insulating material 17 .

Further, according to the refrigerator 100, the elongated hole 16d for visual confirmation of the rivet 20 is formed in the fixing sheet metal 16 facing the fixing hole 16c for the rivet 20 on the extension thereof. As a result, when the fixing sheet metal 16 is temporarily fixed to the inner box 12 by the rivets 20, the positions of the fixing holes 16c of the fixing sheet metal 16 can be visually confirmed, thereby facilitating the assembly work.

Furthermore, by forming long holes 16d for visual confirmation of the rivets 20 between the pair of convex surfaces 16b of the fixing sheet metal 16, the space between the outer box 11 and the inner box 12 is filled with the foam insulation material 18. In this case, the foam insulation material 18 can be easily filled. Therefore, since the foam heat insulating material 18 is completely filled in the U-shaped gap of the fixing sheet metal 16, it is possible to prevent the fixing sheet metal 16 from moving.
