<p>A damper flywheel, comprising: a primary wheel (3) that is connected to receive a rotational force from a power supplier and is provided with an arc-type damping space (1) which forms a concentric shaft with a rotary shaft of the rotational force therein; a secondary wheel (5) that is joined to be comparatively rotatable by forming the concentric shaft with the primary wheel (3) and is connected to draw power to a rotational load; and an elastic unit (7) that is disposed in the damping space (1) to supply an elastic force in response to the comparative rotation of the primary wheel (3) and the secondary wheel (5), wherein the elastic unit (7) includes one or more coil springs (9) and two or more slide guides (13) that are provided with a pressing unit (11) that supports an end of the coil spring (9), are installed to be slidable on an arc-type trajectory of the damping space (1), and are inserted or drawn while being inter-guided on the arc-type trajectory.</p>
