Wind mill blades are mounted on spokes provided on a power shaft via springs, and thereby in an ordinary wind velocity the wind mill blades are adjusted into a prescribed angle, while in a storm they are made parallel to the direction of a wind, thus enabling the wind mill blades, etc., to be prevented from being damaged and the wind mill blades to be large-sized.

A power electric generator comprising: (a) a power shaft having a horizontal axis of rotation and a support column, said power shaft rotatably coupled to said support column for free rotation about a vertical axis; (b) a plurality of spokes radially extending from said power shaft; (c) a plurality of springs having first and second ends, with first ends connected to said spokes; (d) a plurality of wind mill blades, each blade spaced apart from said spokes by at least one spring, said springs having said second ends supporting said blades and biasing said blades in a first extreme position facing typical air currents for rotation of said power shaft about said horizontal axis and about said vertical axis to align said power shaft parallel the direction of the air current, said springs providing a force such that storm type air currents move said wind mill blades to a second extreme position parallel to said storm type air currents, said power shaft rotation about the horizontal axis causing rotation of a main shaft of an electric generator.
