A dust suction port of a vacuum cleaner is provided to eliminate dust and foreign matters from a duster easily by enlarging an external air suction body, and to function as a dustpan by mounting a blade in the body. A dust suction port is combined with an intake pipe(160) of a vacuum cleaner and composed of a body(210) opening one side and having a collecting space for sucking and collecting dust, a handle part(260) integrally combined with the body and composed of a discharge passage to flow dust from the collecting space to the intake pipe, and an intake regulating unit(300) installed to the handle part to regulate the amount of suction flowing into the intake pipe. The intake regulating unit comprises a fitting sill formed in an edge of the handle part, an adjusting hole formed in a guide surface of the fitting sill, and an adjusting ring inserted between the fitting sills to regulate suction air.
