PROBLEM TO BE SOLVED: To prevent the scattering at rupture besides reducing the weight of a Darrieus rotor. SOLUTION: The device is constituted of a vertical rotary shaft 11 rotatably supported by a body case 9, a wind-turbine part 3 formed by combining a Darrieus rotor 15 and a Savonius rotor 13 provided to the rotary shaft 11 and a power generating part 5 made up of a stator 45 arranged and rotationally supported in the body case 9 and a rotor 47 rotating together with the rotary shaft 11. The Darrieus rotor 15 in the windmill part 3 is bent in an arc shape of a wing-like shape having a hollow in a cross section to mount both upper and lower ends in the rotary shaft 11 via mounting members 25. A rope 41 for scattering prevention is provided in the rib 39 provided to inside spaces on both sides of the Darrieus rotor 15 so as to be disposed along the rib 39, whereby preventing the scattering.
