[Features] It is a long disc spring bent with a constant curvature, and the restoring force (load) generated when it is stretched in a straight line is constant regardless of the stroke. -Once the maximum force is reached, the force remains constant regardless of how far the stroke is extended. (Maximum power is not reached until the drum has completed approximately 1/2 revolution).
