Abstract
The present invention relates to a disc package having a structure in which a cover can be fixed on a base by simply pressurizing the cover with respect to the base in a base shaft axial direction and, at the same time, the cover can be prevented from being accidentally separated from the base while the disc package is being transported. Further, in the disc package, a cover once fixed on a base can be separated therefrom by rotating the cover along the circumference of the base in any direction, i.e., in either a clockwise or a counterclockwise direction. Furthermore, an end portion of a shaft can be fitted into a concave portion of a cover even in case the end portion of the shaft is not aligned with the concave portion of the cover.
