The present invention provides a vibration isolation apparatus for a projectile including an elastic damper to effectively reduce the transfer of vibration and impacts to a main target. According to the present invention, the vibration isolation apparatus for a projectile including an elastic damper supports a projectile from a prescribed support body, reduces vibration, and comprises: a first support unit having a passing hole vertically penetrated therein; a first vibration reduction unit including a moving plate provided in the passing hole and connected to the support body, and an elastic damper connecting the gap between the outer circumferential surface of the moving plate and the inner circumferential surface of the first support unit, and formed to be elastically deformed in a direction parallel with a virtual extension line connecting the outer circumferential surface of the moving plate and the inner circumferential surface of the first support unit to reduce vibration in an x-axis and a y-axis direction; a second support unit separated from the first support unit, and connected to a projectile; and a second vibration reduction unit provided to connect the first support unit and the second support unit to each other, and reducing vibration in a z-axis direction.
