PROBLEM TO BE SOLVED: To provide a movable blade structure in which a fluid pressure load is settled within a fixed range by making a drag blade, provided on a cylindrical inner wall, profiling-movable in a downstream direction in accordance with fluid pressure in the case where a rotary drum formed from a hollow cylinder is used as a power section, and changing an opposing angle of a drag blade face in a flow direction in accordance with drag.SOLUTION: A cylindrical drum per se is used as a rotational power section by a drag blade D provided on a cylindrical inner wall B, a drag blade support shaft fulcrum to the cylindrical inner wall B is located at a predetermined position closer to an upstream side of the drag blade, and a drag blade support shaft orthogonal to a cylindrical inner wall surface is used as a movable shaft support elastically rotating in a predetermined direction within a circular wall. Therefore, a drag blade surface is made profiling-movable in a downstream direction in accordance with fluid pressure increase with respect to a reference setting of a drag blade face opposing angle, and stable power can be obtained in a rotary part of a small power generation device to which unstable natural fluid energy is applied. |
