PROBLEM TO BE SOLVED: To provide an underwater propulsion apparatus not only compactly fixable to an oxygen cylinder carried by a diver but also enabling the diver to easily change its propulsion direction without using the self-force of the diver. SOLUTION: The underwater propulsion apparatus 100 providing propulsion force to the diver comprises a pair of propulsion units 110, 120 fixed to the right and left sides of the oxygen cylinder 400 carried by the diver. Each of the propulsion units 110, 120 comprises at least a motor, a housing storing the motor, and a screw positioned at the rear of the housing and driven by the motor. Also, the motor of each of the propulsion units 110, 120 is connected to a motor control means controlling the rotational speed of the motor. COPYRIGHT: (C)2007,JPO&INPIT
