- connection area 223 may connect the first area 221 and the second area 222 at an angle. Accordingly, it is possible to minimize line-shaped scratches that may occur on the exterior of the secondary battery 10 due to the stepped edges formed by the first region 221 and the second region 222 .
- connection area 223 facing the secondary battery 10 may be formed as a curved surface in order to more effectively prevent the occurrence of the line-shaped scratches.
- the lower support part 220 may have various materials. However, since it comes into contact with the center of the lower end of the secondary battery 10, it is preferable to use a synthetic resin material to minimize damage to the external appearance of the secondary battery 10.
- the lower support part 220 may be made of an ABS (Acrylonitrile Butadiene Styrene) resin material including acrylonitrile, butadiene, and styrene.
