Abstract

PURPOSE: To adjust windy energy to be utilized by each turning a plurality of slender sail pieces supported rotatably to an outer frame, forming openings among the sail pieces and adjusting the areas of said openings.
CONSTITUTION: The outer frame structure consisting of a longitudinal frame 2 and sail girders 3 is mounted to a mast 1 through a shaft 5 of a sail device. Both end sections of a plurality of each slender sail piece 4 are supported rotatably to the longitudinal frame 2. Each sail piece 4 is turned until the projections of shafts 6 for the sail collide with stoppers 7 centering around said shafts 6 by pulling a wire 10 for extending the sail, and each sail end is joined mutually and one sail is formed as a whole. Each sail piece 4, on the other hand, is rotated until they collide with stoppers 8 in the direction that gearing is unfastened mutually by pulling a wire 11 for contracting the sail, and set where making a wind escape.
