Disclosed is a counter rotating device. A counter rotating device according to an embodiment of the present invention includes: a driving shaft; a driven shaft rotating around a central axis identical to the driving shaft, formed into a hollow shape to enable the driving shaft to penetrate, and rotating in a direction opposite to the driving shaft; a counter rotating unit rotating the driving shaft and the driven shaft in opposite directions; a first driving shaft rotating member joined to the driving shaft protruding from an output side of the counter rotating unit and integrally rotating with the driving shaft; a first driven rotating member joined to the driven shaft protruding from the output side of the counter rotating unit, integrally rotating with the driven shaft, and having a fixated load; and a first rotation inducing member interposed between the first driving shaft driving member and the first driven shaft rotating member and inducing the relative rotation of the first driving shaft rotating member and the first driven shaft driving member. The purpose of the present invention is to provide the counter rotating device facilitating the installation of a heavy object such as a propeller in the hollow driven shaft.
