Boss Cap having Asymmetry Type Fin and Propulsion Apparatus for Ship

摘要

The present invention relates to a boss cap having an asymmetric pin and a vessel comprising the same. The boss cap comprises: a cap which is coupled to a boss to which a propeller rotated by a driving force generated by a driving unit is coupled, and a pin having a first pin surface facing a first direction perpendicular to a direction projecting from the cap and a second pin facing a second direction opposite to the first direction. The pin and the propeller are formed to be asymmetrically protruding in the first direction, respectively, and the first and the second pin surfaces are located on the first direction with reference to a pin reference line connecting one end and the other end of the pin. The present invention intends to provide a boss cap having an asymmetric pin capable of dispersing a vortex generated in the rear of a boss, and a propulsion device for a vessel comprising the same.
