PURPOSE: An underwater propulsion device using a jet principle is provided to rotate two propellers by powering an underwater motor when an emergency. CONSTITUTION: An underwater propulsion device using a jet principle comprises a first body(10), a second body(20), an underwater motor(50), a first propeller(60), a second propeller(60a), and a fixture(70). A first outer body(11), a first receiving part(12), a first inner body(13), and a first hinge(15) are formed in the first body. A second hinge coupled to the first hinge is formed in the second body. The second body has a second outer body(21), a second receiving part(22), and a second inner body(23). The first and second propellers are formed in both sides of the underwater motor and are rotated. The fixture is coupled to the first and second hinges. |
