Claim:
1. A tilt-type rotation blade apparatus for vertical-type power generation, the tilt-type rotation blade apparatus comprising: a vertical power shaft; a wind direction cooperation member installed independently from the vertical power shaft to rotate according to change of a wind direction; a tilt drum vertically fixed to the wind direction cooperation member and including a rail formed along a side-outer circumference thereof; a blade member including a blade stem and a blade plate to revolve around the tilt drum in a horizontal direction by wind power while applying rotational force to the vertical power shaft; and a tilt guider having one end fixed to a center of an end of the blade stem and an opposite end installed in the rail to move along the rail when the blade member revolves, wherein the rail includes a forward rail part and a backward rail part having a linear shape, bi-directionally spaced apart from a revolution path of the blade member by an equal distance, alternately formed at an interval of 180°, and linked with each other by one pair of switching rail parts having an oblique shape, and the tilt guider moves along the forward rail part such that the blade plate becomes vertical to the wind direction when the blade member revolves in a forward direction of the blade member, which is identical to the wind direction, moves along the backward rail part such that the blade plate becomes horizontal to the wind direction when the blade member revolves in a backward direction, which is opposite to the wind direction, and passes through the switching rail parts to allow the blade member to self-rotate at an angle of 90° such that the blade plate is tilted vertically or horizontally to the wind direction.
