According to the present invention, the hull stern structure for supporting a propeller shaft comprises: a propeller shaft wherein a propeller of a ship is mounted on one end thereof, and the other end thereof is connected to a main engine of the ship; and a stern tube bush which encloses and supports the propeller shaft. An inclined surface is formed on an inner circumferential surface of the stern tube bush to allow an inner radius of the stern tube bush to gradually become larger towards an end of the outside thereof. Accordingly, the propeller shaft can be flexibly supported even when shaft alignment is not maintained by an external force of a vibrational load or the like applied by vibration or the like such as rolling, pitching, yawing, or abrupt turning applied to the ship when sailing the ship in addition to a static load and a dynamic load of the propeller shaft to prevent heat generation and damage to the propeller shaft. |
