Conveying device

The invention relates to a conveying device for conveying a long sheet-shaped base material in a battery manufacturing process. When a base material is conveyed in a battery manufacturing process, friction between a roller and the base material can be prevented. The conveying device is characterized in that the conveying device is provided with a roller for conveying a base material; a shaft penetrating through the roller; a bearing disposed between the roller and the shaft; and a drive device that rotates the axial direction in the same direction as the conveyance direction of the base material in accordance with the conveyance of the base material. 本发明涉及输送装置，在电池的制造工序中输送长条片状的基材。在电池的制造工序中输送基材时，能够防止在辊与基材之间产生摩擦。输送装置的特征在于，具备：输送基材的辊；贯通辊的轴；设置在辊与轴之间的轴承；以及与基材的输送相应地使轴向与基材的输送方向相同的方向旋转的驱动装置。
