PURPOSE: A dredging device for a lateral sewer of a street inlet is provided to prevent the submersion of a road or a house by discharging rainwater or wastewater rapidly. CONSTITUTION: The dredging device for a lateral sewer of a street inlet comprises: a driving unit(10) generating rotary power; a rotational control unit(20) rotated by the driving unit and shifting the rotary direction at need; a flexible cable(30) connected to the rotational control unit(20), rotated and approached into a street inlet at the bending state; and a flexible screw conveyor(40) connected to the end of the flexible cable(30), rotated and approached into a lateral sewer through an opening of a lateral sewer(5) at the bending state.
