A spring box is made of a spring with an upper support area and that lower, formed by corresponding coils of the ends of the spring in the plane, perpendicular to axis thereof, between the support areas a pressure area, having the bicone design, is formed. In doing so the ends of the spring coils of the upper and lower support areas have the radius not exceeding the maximum radius of the coils of the pressure area. |
