<p>PROBLEM TO BE SOLVED: To prevent loosening, etc., of a sheet-like member by effectively utilizing the centrifugal force produced by rotation of a rotating body to sure hold the end when this end is held in the wrapping around direction of the sheet-like member after the sheet-like member to be wrapped around the rotating body is wrapped around the rotating body. SOLUTION: The centrifugal force by the high-speed rotation of the rotating body 200 makes it possible to obtain an adequate shape and the holder of the structure by considering the distance L1 from the position of a fulcrum 206 to a clamping section 212, the distance L2 to the centroid, the position of the centroid, the weight (m) per unit length in the axial direction of the rotating body in a plate 150, the thickness size (t) and density (c) of the sheet-like member 202 and the coefficientsμ1 andμ2 produced with the sheet-like member 202. (μ1+μ2)×(L1/L2)×m}>c×r×t...(1).</p> |
