Claims

[Scope of utility model registration request]

It has an inner shaft that is rotationally driven by the main engine, a rear propeller attached to the rear end of the inner shaft, and a tubular outer shaft that is connected to the inner shaft through a reversing mechanism and overlaps with the inner shaft. , a front propeller attached to the rear end of the outer shaft and disposed in front of the rear propeller, and an inner shaft bearing attached between the outer periphery of the inner shaft and the inner periphery of the outer shaft. and a lubricating oil supply system that supplies lubricating oil to the inner shaft bearing via the internal oil passage of the inner shaft, and the lubricating oil supply system is connected to a lubricating oil supply source to supply lubricating oil to the inner shaft bearing. The structure includes a floating ring-shaped oil chamber surrounding the shaft, and an oil supply hole drilled in the inner shaft to communicate the oil chamber with the internal oil passage of the inner shaft. A marine vessel, characterized in that a magnet is provided to capture iron powder therein, and a strainer net is provided at or near the oil supply hole to capture foreign matter in the lubricating oil passing through the oil supply hole. Counter-rotating propeller device.
