Abstract

A dust collector for a vacuum cleaner, including a first cyclone disposed within an outer case to filter out dust from air introduced from an outside thereof and introduce the air from which dust has been filtered out to an inside thereof, a second cyclone accommodated in the inside of the first cyclone to form a first space between the first cyclone and the second cyclone to separate fine dust from the air introduced to the inside of the first cyclone, and a guide vane spirally extended along an inner circumference of the second cyclone to induce rotational flow to the air introduced to an inside of the second cyclone through an inlet of the second cyclone via the first space, wherein the guide vane is integrally provided on the second cyclone.
