ジエツト推進装置。 In a waterjet propulsion device in which a dirt removal device is provided in an inlet duct near the suction port of an impeller of a waterjet pump, the dirt removal device is fitted into an opening formed in the upper surface of the inlet duct and into this opening. A dirt collecting flange, a flexible diaphragm stretched over the flange so as to close the opening, and a watertight valve located closer to the inlet duct than the diaphragm and disposed in the flange so as to be openable and closable. A waterjet propulsion device comprising: an outer cover that closes the opening on the outside of the diaphragm; and a duct rectifying plate that is openable and closable at a portion of the opening on the inlet duct side.
