Claims

[Scope of utility model registration request]

A contra-rotating marine propeller consisting of a main engine, a reversing transmission, an inner shaft and a tubular outer shaft forming coaxial double shafts, a rear propeller attached to the end of the inner shaft, and a front propeller attached to the end of the tubular outer shaft. In the device,
A counter-rotating marine propeller device comprising an inner shaft bearing coaxially supporting an inner shaft on the inner circumferential surface of an output end of a tubular outer shaft of a reversing transmission device.
