Abstract: A one piece fan blade for a wind machine is sandwiched between a hub and a plate, the fan blade and the hub and is secured thereto by a teeter pin extending through the bore from opposed passageways in the hub. The shaft is centered in the bore of the hub to permit tilting of the hub about an axis coincident with the teeter pin to an angle commensurate with the spacing intermediate the shaft and the bore. Apparatus at the extremities of the teeter pin reduce wear on the teeter pin retaining plates and contribute to lubrication of the opposed journals.
