Abstract
A rotating cylinder device includes a cylindrical belt having an axis line, several plate-shaped parts, several link mechanisms, and a cylindrical casing. The plate-shaped parts are disposed outside the belt and arranged symmetrically across the axis line. The link mechanisms are pivotally connected to the respective plate-shaped parts and each have a moving protrusion. The moving protrusions are adapted to move along a first direction parallel to the axis line. The cylindrical casing is adapted to rotate about the axis line and is coupled to the moving protrusions. When the cylindrical casing rotates about the axis line, the moving protrusions are driven to move along the first direction, and the plate-shaped parts are driven by the link mechanisms to move along a second direction perpendicular to the axis line, to contract the belt.
