Claims

[Scope of utility model registration request]

In a shaft system device consisting of a tubular outer shaft and an inner shaft each having a front propeller and a rear propeller at the rear end of a contra-rotating marine propeller, a hollow shaft of a two-split type inserted in the tubular outer shaft is , a coupling part between the intermediate shaft and the propeller shaft in the inner shaft, the coupling part being a flange provided at the rear end of the intermediate shaft, an assembly type flange connected to the flange, and the assembly type flange. and a tapered portion formed at the front end of the propeller shaft to be tightly fitted into the tapered inner circumferential surface of the propeller shaft.
