Beschreibung
Zusammenfassung:	PURPOSE: A propulsion device and a ship with the same are provided to transfer power to a front propeller without using an outer shaft by directly connecting the front propeller and a driven gear of a reverse rotating device. CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), and a reverse rotating device(70). The rear propeller is fixed in a driving shaft. The front propeller is rotatably supported in the driving shaft in front of the rear propeller. The reverse rotating device reverses the rotation of the driving shaft and transfers the reversed rotation to the front propeller. The reverse rotating device comprises a driving gear, a driven gear, a first pinion gear, and a second pinion gear. The driving gear is fixed in the driving gear. The driven gear is connected to a front propeller hub. The first pinion gear is engaged with the outside of the driving gear. One side of the second pinion gear is engaged with the first pinion gear and the other side thereof is engaged with the driven gear.
