Embodiment Construction
[0066] image 3 Shown is a refrigerator housing according to a preferred embodiment of the present invention. In the following description, for the figure 1 The same elements are given the same reference numerals.
[0067] refer to image 3 , the base plate 51 of the case 50 defining the appearance of the refrigerator is made of an iron plate with a thickness of about 3 mm to 10 mm. A predetermined pattern 51 a is formed on the front surface of the case 50 . When substrate 51 is rolled (60 and 60 ', see Figure 4 ) rolling, the front surface of the substrate 51 is pressed into the shape of the uneven portion 61 of the outer periphery of the roller 60 that is closely attached to the front surface of the substrate 51, thus providing the pattern 51a.
[0068] For example, if the uneven portion 61 of the roll 60 is formed in waves, the pattern 51 a is formed in waves on the front surface of the substrate 51 . Here, the thickness of the pattern 51 a of the substrate 51 is det...
