And a power storage device that generates [0003] Such devices are used in certain fields of use.
Results in better vibration or noise characteristics
However, this device is often a compromise solution.
It doesn't work. This pure mechanical solution is completely different
Operating conditions with different vibration and noise characteristics.

I can't. Therefore, such devices have many operating conditions.
The more you try to catch, the more expensive and expensive
You. Because for the additional amplitude range,
This is because each requires complicated procedures. Especially this
Such devices are suitable for multiple operating conditions with varying damping characteristics
I can't let that happen. This is because individual damping stages or
Indicates that hysteresis belonging to the energy storage device
This is because it cannot be changed according to the conditions of production. Moreover
This device is vulnerable to wear and failure. In a conventional device of the type described at the outset,
Is a relatively small rotational elastic phase between the flywheel parts.
Since only counter rotation is possible, at least this relative rotation
Effective damping between flywheel sections over a large area
The attenuation value of the member is relatively high. But many use eyes
It is necessary to achieve good damping of vibration
Large relative rotation is given between the wheel parts
Is more advantageous. Because the amplitude
This is because large vibrations are more effectively damped. SUMMARY OF THE INVENTION Problems to be Solved by the Invention
The problem is that the damping effect of such a device is improved,

Medium is extruded through a gap 54 which acts like a throttle.
Is done. The other part of the viscous medium is
It can be moved between the passage-shaped receiving portion 51 and the wall. First
The viscous medium displaced inward is centrifuged to act on it.
Again, it is distributed evenly in the circumferential direction based on the force. Outside
When the spring 45 is loosened, the spring 45
Is a similar type of viscous medium on the other side.
Pushed through the gap and moved through the gap 54
And the spring 45 is again actuated by the centrifugal force acting on the medium.
Satisfies. Damping caused by viscous media
Is related to the centrifugal force acting on the medium. In other words, the rotation speed
As the size increases, the damping effect also increases. For the viscous medium of the radially inner spring 48
