The present invention belongs to a spring. A damping structure, which can damp the motion of the spring and contains high-damp liquid material, is arranged on the body of the spring. Since the damping structure is arranged on the body of the spring, when the spring is stressed to generate vibration or deformation, the high-damp liquid material is also deformed, great internal friction is generated inside the high-damp liquid material to absorb partial energy, so that the deformation is hindered and the vibration is attenuated, and since noise is also caused by the vibration, the noise is greatly reduced as well. Since the spring adopts the highly viscous high-damp liquid material, the spring can provide a relatively high damping ratio, which is sufficient for the vibration reduction of most of mechanical devices and vehicle structures, and even in a case requiring a high damping ratio, the needed extra damp is much less. Normally, an additional damping device is no longer needed, and therefore the structure is simplified. Moreover, the spring effectively eliminates the sympathetic vibration of self under the inherent frequency.
