摘要：PROBLEM TO BE SOLVED: To provide a sheet material holding drum which is lightweight and has sufficient mechanical strength in a direction orthogonal to the axial direction of a rotary shaft. SOLUTION: A rotary drum 220 is arranged coaxially at prescribed distances, and a drum main body 222 is formed by connecting the parts 224 of the cylindrical main body to each other by means of reinforcement bars 230 at an eccentric position. Thereby, a space is formed between the main body parts 224 along the axial direction of the main body 222 of the drum. Accordingly, weight is reduced compared to the case that the cylindrical or columnar drum main body is uniformly arranged along the axial direction of the drum main body 222. Because the main body parts 224 are connected by means of the reinforcement bars 230 at a position eccentric from the axial center, rigidity in the radial direction is strengthened.
