<p>PROBLEM TO BE SOLVED: To provide a flywheel power unit in which strict horizontal alignment is not necessary and which is strong against transverse waves of earthquakes and the like. SOLUTION: In a flywheel power unit, a recessed reception hole 10 is formed above a flywheel 2, a short shaft 11 is protrusively installed on a casing 1 side and the reception hole of the flywheel 2 is engaged with the short shaft 11 of the casing 1 is mode idlene so that it is freely rotatable. In the device, since the force due to rotation acts in the direction opposite to a conventional case, even if the upper part of the flywheel 2 vibrates and the reception hole 10 is brought into contact with the short shaft 11, and therefore the device tends to be restored easily to a noncontact state.</p> |
