Abstract
PURPOSE:To improve a flexible effect at high speed run by thickening forward and rearward end parts of a fan blade. CONSTITUTION:A fan blade 12 is formed on a boss part 11 of a fan equipment 10. Said fan blade 12 is made up of a central trunk part 13, and forward and rear edge side blades 14, 15 which are positioned at the front and the rear. The trunnk part 13 has an approximately elliptic section and gets thinner in the external direction of a radius up to a top 13b of the trunk where its thickness is equal to that of the peripheral area of the blade. Portions close to the respective side edges of the blades 14, 15 gain thickness and widths of the thick portions in the turning direction gain more toward the upper peripheral end. As the result, a position of a gravity point P may be set in access from the side edge to the external periphery, thereby providing a high flexible twist effect.
