Abstract
Bearings (5, 7) fixed to the two ends of a rotation shaft (2) of a motor/generator are pressurized by plate springs 15, 17. The plate springs (15, 17) absorb the deflection off the rotation shaft (2) due to external vibration by the extension and contraction. An effective gaps L is set to value at which the bearings (5, 7) do not collide with the housing (9) in the most compressed state of the plate springs (15, 17). By this setting, the effective gap L is set to a value larger than the maximum amplitude in the direction of the rotation shaft (2) due to the external vibration.
