The present invention relates to a roller curtain for a warship hangar with a reinforced damage prevention function that can prevent damage to the roller curtain due to strong winds. The present invention, in the roller curtain for opening and closing the entrance of the hangar of the warship, pillars vertically installed on both sides of the entrance of the hangar of the warship; A pair of cross arms horizontally connected to the upper and lower portions of the pillars on both sides; A support channel vertically connected to the pair of cross arms; A plurality of buffer members installed at predetermined intervals along the vertical direction of the support channel to buffer the impact of the roller curtain acting inside the hangar by strong wind; It is a technical idea to include an elastic pad for elastically supporting the inner surface of the roller curtain which is shaken by strong wind by connecting the plurality of buffer members up and down. Therefore, the present invention prevents damage of the roller curtain in advance because the elastic pad firstly elastically supports the impact acting on the roller curtain when a strong wind blows on a warship that is always waiting at sea or performs an operation, and the buffer member buffers the secondarily. There is an effect that can be done.
