<p>A vibration damper for a vibrational mechanical body, such as a chain saw or motorcycle, which is a source of vibration, comprises a support, such as an arm of the vibrational body for manipulation, a cylindrical grip mounted on the support, and a vibration-damping coiled spring having a row of small and large coiled portions and disposed between the support and the grip, with each of the small coiled portions being engaged with and supported by the support and each large coiled portion by the inner surface of the grip, whereby the vibration transmitted from the vibrational body to the support is absorbed by the vibration-damping coiled spring to control or lessen the vibration transmission to the grip. Instead of forming a continuous row of barrel-shaped units, the spring may be divided into such separate units or segments, or it may be replaced by a plurality of spiral unit springs for the same functions.</p> |
