ABSTRACT OF THE DISCLOSURE: This invention relates to a profiled blade of a fan and its application in a motor-driven ventilating device. The blade has an axis which is the locus of the thrust centres of its cross-sections parallel to its foot which has a connecting point between an abyssal arc whose concavity faces toward the leading edge and a summit arc whose concavity faces toward the trailing edge of the blade. This blade can be used for the construction of a fan of a motor-driven ventilating device, especially for use in automobiles.
