1. A Magnus-type wind power generator comprising:

  • a horizontal rotary shaft for transmitting a rotation torque to a power generating mechanism; and

    a required number of rotary columns arranged in substantially radial fashion from the horizontal rotary shaft;

    whereinthe rotary columns rotate about axes of the rotary columns, whereby said horizontal rotary shaft is rotated by Magnus lift that occurs due to interaction of wind power with rotation of the rotary columns, and said power generating mechanism is driven;

    said Magnus-type wind power generator characterized in thatan external peripheral surface of said rotary columns has a structure in which a spiral rib formed in a convex shape is provided, and a flow component of air at least parallel to the axes of the rotary columns is generated on the external peripheral surfaces of said rotary columns by the spiral ribs; and

    said spiral ribs are formed so that a lead angle of the spiral ribs is smaller at a distal end of said rotary columns than at a proximal end of said rotary columns near said horizontal rotary shaft.
