Provided are an axial vibration damper and an engine for a ship including the same, wherein the axial vibration damper comprises: a body part arranged such that a crankshaft of an engine for a ship including a cam part in a ring shape can be penetrated, including a pair of oil chambers being in contact with both side parts of the cam part to accommodate oil inside, and at least one intercommunicating hole formed on an upper end of the pair of oil chambers respectively; a lower frame combined with an upper part of the body part, including a cap intercommunicating hole connected to the intercommunicating hole at a predetermined angle; and an upper cover combined with an upper end of the lower frame to form an oil intercommunicating flow path together with the lower frame. Accordingly, damping performance can be improved by maximally ensuring a moving path for oil.

    링 형상의 캠부를 구비하는 선박용 엔진의 크랭크 샤프트가 관통되도록 구비되며, 상기 캠부의 양측부와 접하여 내측에 오일이 수용되는 한 쌍의 오일 챔버, 및 상기 한 쌍의 오일 챔버 상단에 각각 형성되는 적어도 하나의 연통구멍을 포함하는 몸체부;상기 몸체부의 상부에 결합되며, 상기 연통구멍과 소정의 각도를 가지면서 연결되는 캡 연통홀을 구비하는 하부 프레임; 및상기 하부 프레임 상단에 결합되어, 상기 하부 프레임과 함께 오일 연통유로를 형성하는 상부 커버;를 포함하는 종진동 감쇠 댐퍼 및 이를 포함하는 선박용 엔진을 제공하여 오일 이동경로를 최대한 확보함으로써 감쇠 성능을 향상시킬 수 있다.
