Claims

[Scope of utility model registration request]

In a propeller shaft disposed at the stern of the ship so as to extend from inside the ship to outside the ship, the front end of the propeller shaft is provided with a coupling for coupling to the rear end of the intermediate shaft, and the coupling has a pyramidal inner wall surface. A pyramid-shaped protrusion that fits into the engagement hole is formed at the front end of the propeller shaft, and a male thread is coaxially formed at the tip of the protrusion. A propeller shaft with a removable coupling, characterized in that a nut is provided that is screwed into a screw and tightens the coupling to the propeller shaft.
