The corner structure includes: a stationary member secured to an inner surface of a hull structure wall; a movable member disposed on the stationary member such that the sealing walls are joined thereto; and an insulating member interposed between the sealing walls and the hull structure wall. The stationary member includes a stationary member body bent at a curved portion thereof in an opposite direction to the movable member, and the movable member includes a movable member body bent at a bent portion thereof in an opposite direction to the stationary member. The stationary member and the movable member are coupled to each other by a fastening member that penetrates the curved portion and the bent portion.
