ABSTRACT:
A toy windmill includes a leaf member and a rod member. The rod member consists of a first large diameter grip rod, a small diameter shaft extending from an upper end of the grip rod, two washers, an action block and a second large diameter rod. The shaft passes through the washers, a post portion of the action block and the second large diameter rod to let the action block freely rotate relative to the rod member. Then the leaf member is assembled with the action block tightly so that the leaf member may rotate relative to the rod member to suit to the direction of wind to let the leaves of the leaf member receive and be rotated by the wind.
