It has a concave portion 12A having a concave shape at a position corresponding to each of the portions 14A. If the elongated recessed portion 12B and the recessed portion 12A as described above are not formed on the load receiving portion surface 12 on which the post portion is located, the top portion of the post portion is located directly on the load receiving portion surface 12. Then, this cargo receiving surface 1
When the film sheet roll is loaded on the sheet 2, the top portion of the post portion slightly projects from the surface of the load receiving portion without the post portion due to the load. In this case, the sheet portion of the sheet roll that is in contact with the projecting post portion receives a large stress for a long period during storage and becomes white. The width and depth of the recess 12A are preferably set so as to prevent protrusion of the post portion that causes such a problem of whitening when stacking the sheet rolls. Further, the width and depth of the elongated recessed portion 12B prevent the protrusion of the post portion that causes such a problem of whitening when stacking the sheet rolls, and consider the molding resin amount accompanying the molding of the central leg.
