PURPOSE: A hinge apparatus of a door for a ship is provided to minimize the friction between a hinge guide part and a hinge bolt shaft by applying lubricating oil, which stays always in the retention space of the hinge bolt shaft, to the exterior of the hinge bolt shaft. CONSTITUTION: A hinge apparatus of a door for a ship comprises a hinge guide part(10), a hinge body(20), a hinge bolt shaft(30), and a hinge nut part(40). The hinge guide part is installed in a door frame and has a vertical coupling hole. The hinge body is supported in the hinge guide part to rotate a door and has a plurality of fixing holes(22) and a through hole(21). The hinge bolt shaft is inserted into the coupling hole and the through hole and supported with the hinge guide part in the rotation of the hinge body. The hinge bolt shaft has a plurality of retention spaces(33) filled with lubricating oil and a lubricant transfer passage(34) for transferring the lubricating oil. The hinge nut part is coupled to the end tip of the hinge bolt shaft and prevents the hinge bolt shaft separating from the coupling hole and the through hole. |
