(42) The first damper protrusions 52 protrude from the first damper body 51. The first damper protrusions 52 may protrude upward from a top surface of the first damper body 51. The first damper protrusions 52 may be disposed to be spaced apart from each other. Accordingly, the first damper protrusions 52 may come into contact with mutually different parts of the one side of the core 100. A contact area of the first damper portion 5 which comes into contact with the one side of the core 100 may be reduced using the first damper protrusions 52. Also, elastic deformation for each of the first damper protrusions 52 may be further smoothly performed. Accordingly, the first damper portion 5 may be implemented to further reduce the level of vibrations, shaking, or the like being transferred to the one side of the core 100. The first damper protrusions 52 may be formed to have a rectangular parallelepiped shape as a whole but is not limited thereto, and may be formed in other shapes capable of reducing the level of vibrations, shaking, and the like being transferred to the one side of the core 100. For example, the first damper protrusions 52 may be formed to have a size which is reduced when gradually protruding upward from the first damper body 51. In this case, parts of the first damper protrusions 52 which come into contact with the one side of the core 100 may be formed to have curved surfaces.

(43) The first damper protrusions 52 may be disposed to be spaced apart from each other in a first axial direction (X-axis direction). The first damper protrusions 52 may be formed to have a greater length in a second axial direction (Y-axis direction) in comparison to a length in the first axial direction (X-axis direction). The second axial direction (Y-axis direction) and the first axial direction (X-axis direction) are perpendicular to each other in one plane. When the first damper portion 5 is coupled to the first support portion 3, the copper foil 200 may be accommodated in the accommodation body 2 to be parallel to the second axial direction (Y-axis direction).

(44) The first damper protrusions 52 may be formed to have the same length on the basis of the first axial direction (X-axis direction). As shown in FIG. 12, the first damper protrusions 52 which are disposed further outward from a central point CP on the basis of the first axial direction (X-axis direction) may be formed to have a greater length. The central point CP means a point spaced at the same distance apart from the both ends of the first damper body 51 on the basis of the first axial direction (X-axis direction). Also, when being further outward from the central point CP on the basis of the first axial direction (X-axis direction), a gap between the first damper protrusions 52 may increase.

(45) The first damper portion 5 may include a plurality of first damper grooves 53. The remaining part of the first damper portion 5 excluding parts in which the first damper grooves 53 are formed may be coupled to the first support portion 3. The first damper grooves 53 may be formed in a bottom surface of the first damper body 51. The first damper grooves 53 may be formed to have a rectangular parallelepiped shape parallel to the first axial direction (X-axis direction). The first damper grooves 53 may be disposed to be spaced apart from each other in the second axial direction (Y-axis direction). A contact area of the first damper portion 5 which comes into contact with the first support portion 3 may be reduced using the first damper grooves 53. Also, elastic deformation for the first damper body 51 may be more smoothly performed due to the first damper grooves 53. Accordingly, the first damper portion 5 is implemented to reduce the level of vibrations, shaking, or the like being transferred from the first damper body 51 to the first damper protrusions 52 so as to further reduce the level of vibrations, shaking, or the like transferred to the one side of the core 100. The first damper grooves 53 may be formed to have a rectangular parallelepiped shape as a whole but is not limited thereto, and may be formed in other shapes capable of reducing the level of vibrations, shaking, and the like being transferred. For example, the first damper grooves 53 may be formed to have a size which is reduced when gradually receding upward from the first damper body 51. In this case, an inner wall of the first damper body 51 in which the first damper grooves 53 are formed may be formed to have a curved surface.

(46) As shown in FIG. 14, the first damper portion 5 may be coupled to the first support portion 3 to cover an entire surface of the first support surface 32. In this case, the first damper protrusions 52 may be disposed to be spaced apart from each other along a curvature of the first support surface 32.

(47) As shown in FIG. 15, the first damper portion 5 may be coupled to the first support portion 3 to cover a part of the first support surface 32. When the copper foil 200 wound on the core 100 is accommodated in the accommodation space 21, the first damper portion 5 may be coupled to the first support portion 3 to be disposed below the one side of the core 100.

(48) Here, the copper foil accommodation apparatus 1 according to the present disclosure may include a plurality of such first damper portions 5. The first damper portions 5, 5, and 5 may be coupled to the first support surface 32 at positions spaced apart from one other. Although three first damper portions 5, 5, and 5 are coupled to the first support surface 32 in FIG. 15, the present disclosure is not limited thereto and two or four or more first damper portions 5 may be coupled to the first support surface 32.

(49) When the copper foil accommodation apparatus 1 according to the present disclosure includes the first damper portions 5, 5, and 5, the first damper portion 5 may be disposed below the one side of the core 100 and the first damper portions 5, and 5 may be disposed on both sides of the first damper portion 5 on the basis of the first axial direction (X-axis direction). The first damper portions 5 and 5 may be disposed to be spaced apart ambilaterally from the one side of the core 100. The first damper portions 5 and 5 may come into contact with the one side of the core 100.

(50) As shown in FIG. 15, all the first damper portions 5, 5, and 5 may be implemented to have the first damper protrusions 52.

(51) As shown in FIG. 16, the copper foil accommodation apparatus 1 according to the present disclosure may be implemented through a combination of the first damper portion 5 and a first auxiliary damper 20. Unlike the first damper portion 5 implemented to come into partial contact with the one side of the core 100 using the first damper protrusions 52, the first auxiliary damper 20 may be formed to come into entire contact with the one side of the core 100. That is, the first auxiliary damper 20 may be implemented without the first damper protrusions 52. In this case, a surface of the first auxiliary damper 20 which comes into contact with the one side of the core 100 may be formed to have a curved surface. Since the manufacturing costs of the first auxiliary damper 20 is lower than that of the first damper portion 5, the manufacturing costs of the copper foil accommodation apparatus 1 according to the present disclosure may be reduced through the combination of the first auxiliary damper 20 and the first damper portion 5. The first auxiliary damper 20 and the first damper portion 5 may be formed of different materials. The copper foil accommodation apparatus 1 according to the present disclosure may include a plurality of such first auxiliary dampers 20. In this case, the first damper portion 5 may be disposed below the one side of the core 100, and the first auxiliary dampers 20 and 20 may be disposed on both sides of the first damper portion 5 on the basis of the first axial direction (X-axis direction). The first auxiliary dampers 20 and 20 may be disposed to be spaced apart ambilaterally from the one side of the core 100. The first auxiliary dampers 20 and 20 may come into contact with the one side of the core 100.

(52) As shown in FIG. 17, on the basis of the second axial direction (Y-axis direction), the first damper portion 5 may be formed to have the same length as that of the first support surface 32. The first damper portion 5 may be disposed at a middle position spaced at the same distance apart from both ends of the first support portion 3 on the basis of the first axial direction (X-axis direction).
