摘要： A centrifugal fan that is light in weight and has a structure that restrains vibration are provided. The centrifugal fan includes a resin upper casing, a resin lower casing, an impeller, a motor, and a circuit board. The impeller, the motor and the circuit board are housed between the resin upper casing and the resin lower casing. Radial ribs and a concentric ribs for reinforcing are formed at a bottom surface of a concave part of the lower casing. Resin pins are provided in a standing manner at these rib parts, and the circuit board is fixed to the lower casing by the resin pins.

摘要： The present invention provides a centrifugal fan that can be easily positioned when it is installed in a device or apparatus, which can further improve positioning accuracy, and which can decrease noise, even if it is made thin. In the centrifugal fan in which an impeller is received inside a casing and air drawn in from a suction port formed on the casing by rotating the impeller is discharged from the casing to the outside of a blowing port, a circular protruded portion is formed on a peripheral edge of the suction port, and protrudes upwardly in a shaft direction from an upper surface of the casing.
