PROBLEM TO BE SOLVED: To provide a centrifugal dust collector capable of increasing a rotating-directional component of a rotational flow by fixed vanes installed in a separation chamber even if a force of a pressure-feed or suction device is strong and the axial component of the flow rate of the rotational flow generated in the separation chamber is large. SOLUTION: This centrifugal dust collector is provided with the separation chamber 4 having an approximately cylindrical inner shape and centrifuging dust from an air flow including the dust by the rotational flow C, a suction port 2 tangentially passing the air flow A including the dust to the separation chamber 4, a dust collecting chamber 5 communicated with the separation chamber 4 and collecting the separated dust, and an exhaust tube 7 exhausting an air flow D separated from the dust to the outside of the centrifugal dust collector 1; and is installed with the fixed vanes for increasing the rotating-directional component (f) of the flow rate (g) of the rotational flow B in the separation chamber 4. The area of the flow channel of the rotational flow is reduced when flowing among the fixed vanes, thereby the flow rate of the rotational flow B in the separation chamber is increased so as to weaken the axial component of the rotational flow B and enlarge the rotating-directional component.
