摘要： Sail movement is achieved having rotation while revolving, using a simple structure that does not easily break. A sail device includes a supporting body, a sail body, a guide track comprising recessed portions, and engaging portions. Rotational energy is output from or input to a rotating body forming part of the supporting body. The sail body is attached to the supporting body which freely rotates, and revolves around an axis of the supporting body. The sail body converts fluid energy into rotational energy or converts rotational energy into fluid energy on the basis of the motion of the sail body which contacts a fluid. In the guide track, two recessed portions are continuous with one another, and form an endless track which defines an angle of rotation of the sail body during the process of revolving. The engaging portions engage the sail body with the guide track, and displace the sail body along the guide track.

摘要： [Problem] To achieve a sail movement comprising rotation while revolving, using a relatively simple structure that does not easily break. [Solution] A sail device 1 includes a supporting body 2, a sail body 4, a guide track comprising recessed portions 5a, 5b, and engaging portions 8a, 8b. Rotational energy is output from or input to a rotating body 2c forming part of the supporting body 2. The sail body 4 is attached to the supporting body 2 with freedom to rotate, and revolves around an axis of the supporting body 2. The sail body 4 converts fluid energy into rotational energy or converts rotational energy into fluid energy on the basis of the motion of the sail body 4 which is in contact with a fluid. In the guide track, the two recessed portions 5a, 5b are continuous with one another, forming an endless track which defines an angle of rotation of the sail body 4 during the process of revolving. The engaging portions 8a, 8b engage the sail body 4 with the guide track, and cause the sail body 4 to be displaced along the guide track.
