<P>PROBLEM TO BE SOLVED: To provide a power transmission device for a wind power generator which holds effect of the power transmission device for the wind power generator and is further compact and low-cost. <P>SOLUTION: The power transmission device for the wind power generator includes: a wind shelter plate 5 which is opposed to a wind direction to a contrary wind receiving face part 4 of a helical blade 2 over the entire vertical direction of the helical blade 2 on the outside of a rotating body B with the helical blade 2 disposed on the outer circumference of a rotating shaft 1, is concentric with the rotating body, and is supported so as to rotate around the rotating body; and a guide plate 6 for rotating the wind shelter plate 5 to face the wind direction to the contrary wind receiving face part 4 according to the wind direction. The wind shelter plate 5 is formed in a quarter arc with an axis concentric with the rotating body. The guide plate 6 is consecutively provided at one end of the wind shelter plate 5, in parallel with a center line B1 in a radial direction of the rotating body passing through the other end of the wind shelter plate 5, so that a front end 60 is positioned on the outside than the outermost circumference of the rotating body B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
