To largely relieve positioning between a packaging box and bodies to be packaged, when the bodies to be packaged are stored in the packaging box.

In a packaging box 1 for storing bodies A to be packaged, each of which has the form of a cylinder or a tube similar to a cylinder, right and left erection plates 3 and 4 erected from a bottom plate 2 are provided with position-correcting functions 5 for correcting the positions of the bodies A placed on the bottom plate 2 and for disposing the bodies A into specific storage positions. The position-correcting functions 5 comprise holding parts 14, each having the shape of nearly semicircular arc in plan view, which are provided in the erection plates 3 and 4 and so constituted as to form storage holding parts 16 for the bodies A by means of right and left holding parts 14 opposed to each other. The holding parts 14 each are provided with a tongue 17. After the bodies A are placed on the bottom plate 2, the erection plates 3 and 4 are erected, and, at the time, the storage positions of the bodies A are corrected with the right and left holding parts 14 and the bodies A are stored into the storage holding parts 16 at the same time.
