For example, a ship propulsion unit, referred to as a Counter / Contra Rotating Propeller (CRP), has two propellers on opposite concentric axes with opposite rotational directions. The propulsion efficiency of the ship can be increased by recovering the rotational kinetic energy of the water that is thrown to the sea through the propeller through the hydrodynamic interaction between the forward propeller and the rear propeller.

In a conventional CRP marine propulsion system, two shafts are rotatably fitted to each other to form a double shaft, in which two motors rotate the double shaft in opposite directions to rotate the two propellers connected thereto in the opposite direction .

However, the CRP ship propulsion system as described above is not only complex in construction, but also has a problem of cost loss due to installation of two motors and an increase in installation volume.

On the other hand, in the past, a device for rotating the two shafts in the opposite direction through the application of the bevel gear has been proposed. Such a device is disclosed in, for example, US Pat. No. 5,890,938. The disclosed apparatus has a structure in which a bevel gear is formed on two shafts rotatably fitted to each other and a bevel gear engaged with the bevel gear is rotated in opposite directions.

However, the above-described conventional apparatus has a complicated structure, has a large manufacturing cost of each component constituting an important component, and has a problem that the design of the two shafts rotating in opposite directions is limited.
