In such a flywheel device, for example, if a vertically upward impact is applied to the casing 4, this impact force will move the annular piston 11a through the thrust bearing 5a and the spring 1.
0aK, and push it into the pressure chamber 12a. Therefore, the pressure of the oil in the pressure chamber 12a rises, and the first ball 15a is pushed upward, closing the small-diameter oil groove 148 and closing the small diameter oil groove 148.
While preventing the oil from flowing out from inside, due to the increased oil pressure in the pressure chamber 12a, the oil in the pressure chamber 12a is forced through the slight gap between the annular groove 9a and the annular piston 11a. Therefore, the impact force 7j applied to the casing 4 is a force for compressing the spring 10a and a small amount of oil in the pressure chamber 12a between the annular piston 11a and the annular piston 11a. The impact force is consumed by the viscous force flowing into the gap, and a weakened impact force is transmitted to the bearing 3. Therefore, the impact applied to the bearing 3 is significantly alleviated.

In the above description, a flywheel was exemplified as the Takaoki rotor, but the present invention is not limited to a flywheel, and any Taka4011 rotator having a vertical axis can be applied. In addition, although the pressure chamber is exemplified as having an annular groove and an annular piston, several holes hKTh may be provided around the circumference of the sleeve, and the pressure chamber may be formed by these holes and a piston that fits in these holes. . Furthermore, the oil that fills the pressure chamber can be replaced with other viscous liquids.
Further, as an oil outflow passage, a thin groove may be provided in one or both of the piston and the annular structure (or the hole) that constitute the pressure chamber.3. Furthermore, a check valve can be used instead of the small diameter oil groove and ball to supply liquid to the pressure chamber.
