PURPOSE:To prevent horizontal and vertical vibrations and rotation in a bearing of a core caused by a vibration in transit, by providing two points which become axial supporting points of the core, on the inside surface of a magazine for the bearing of a roller-like material. CONSTITUTION:A roller-like material 3 wound and installed to a core supported pivotally on the inside surface of end caps 4, 4' is contained in the hollow inside consisting of a cylindrical body part 1 and two end caps 4, 4' for sealing both ends of the body part 1, and the roller-like material 3 is drawn out to the outside of a magazine from a slot 2 extended along the core axis in the corner of one face of the body part 1. In this case, on the inside surface of the end caps 4, 4', bearing 8, 8' for supporting the core 5 by two points are provided. That is, by providing two supporting points of the core 5 on the inside surface of the bearings 8, 8', the swinging of the core axis and the rotation of the core 5 caused by the vibration of the magazine can be suppressed. |
