PROBLEM TO BE SOLVED: To make high viscosity oil flowing out onto the sea surface, flow easily into a suction port so as to facilitate recovery by forming the suction port of an eductor pump into cylindrical shape, and providing an inward protrud ing edge at the upper end of the suction port. SOLUTION: An eductor pump 3 is fitted to a triangular frame 2 provided with floating bodies 1 at the respective vertexes, and the position relation between a suction port 4 and the sea surface is made adjustable to constitute an oil recovery device S. The eductor pump 3 jets high pressure water (w) from a nozzle 32 to suck oil in the suction port 4 by negative pressure, and transfers the oil to a support ship through a transfer hose 5. The suction port 4 is formed in cylindrical shape, and a wedge-like edge protruded inward is provided at the upper end of the suction port 4 so as to separate oil flowing out onto the sea surface, from the edge tip to make it flow down directly into the suction port 4, this preventing the oil from flowing down along the inner surface of the suction port 4. High viscosity oil exceeding 100,000 cp. can therefore flow down easily into the suction port 4 so as to be recovered efficiently.
