<P>PROBLEM TO BE SOLVED: To provide a turbofan integrally formed with a shroud and a method of manufacturing the same. <P>SOLUTION: The turbofan includes a rotating plate rotated by a driving motor, a plurality of blades having first ends connected to an outer peripheral portion of a front surface of the rotating plate while being arranged in a radial pattern, a shroud having an annular shape and being integrally formed with second ends of the blades, in which the shroud has an inner diameter equal to or larger than a diameter of the rotating plate, and an auxiliary rotating plate having a diameter larger than the diameter of the rotating plate and being fixed to the rotating plate. Since the inner diameter of the shroud is equal to or larger than the rotating plate, the turbofan is integrally formed with the shroud by a mold. <P>COPYRIGHT: (C)2008,JPO&INPIT |
