A dust collecting container attached to the tapered casing of a dust collector for collecting dust taken therein through a suction hose by means of the operation of a forced-draft fan permitting clean air current to be exhausted to the outside through an exhaust pipe, said dust collecting container having an inlet hole at the top connected the peripheral bottom edge of said tapered casing, through which dust is collected inside said dust collecting container, and a conical flange projecting downwards inwards for guiding dust from said inlet hole into the holding space inside said dust collecting container and for prohibiting dust from floating out of said dust collecting container.
