A vibration damper for a vibrational mechanical body, such as a chain saw or motorcycle, which is a source of vibration, comprises a support (2), such as an arm of the vibrational body for manipulation, and a cylindrical grip (3) mounted on the support (2). A vibration- damping coiled spring has units (4) defining small and large coiled portions disposed between the support (2) and the grip (3), with each of the small coiled portions being engaged with and supported by the support (2) and each large coiled portion by the inner surface of the grip (3). The vibration transmitted from the vibrational body to the support (2) is absorbed by the vibration- damping coiled spring to control or lessen the vibration transmission to the grip. <IMAGE> |
