The present invention relates to a propulsive device of a ship. The propulsive device of a ship comprises: a propulsive unit coupled to a stern of the ship to generate a propulsive force for the ship; a first duct unit coupled to the stern to be positioned between the propulsive unit and a prow of the ship; a second duct unit coupled to the stern to be positioned between the propulsive unit and the prow of the ship, and coupled to be placed apart from the first duct unit; and a flow speed control unit controlling a flow of fluid flowing to the propulsive unit from the first and the second duct unit. The flow speed control unit comprises: an acceleration member coupled to the first duct unit to protrude towards an inside of the first duct unit to increase the flow speed of the fluid flowing towards the propulsive unit through the first duct unit; and a speed reducing member coupled to the second duct unit to protrude from the outside of the second duct unit to reduce the flow speed of the fluid flowing to the propulsive unit through the second duct unit. According to the present invention, the propulsive device of a ship allows the flow speed distribution of fluid, passing through the propulsive unit, to be uniform by controlling the flow speed distribution of the fluid, flowing to the propulsive unit through the duct units, using the flow speed control unit; thereby increasing work efficiency of the propulsive unit.
