[Scope of utility model registration request] The core part is divided into a plurality of cores, and a disc clock claw is provided between each core, and the disc clock claw is attached to a cantilever beam connected to the main body only at its base. In a two-piece CD case that has an annular core part in the center of the bottom that stores and holds the disc, which has a gap between it and the main body around the periphery other than the base part because of the shape of the disc. A CD characterized in that at least a part of the gap is closed with a thin film that can be molded simultaneously with the bottom during bottom molding so that the disc clock pawl can act freely.
