<P>PROBLEM TO BE SOLVED: To provide a variable flywheel capable of preventing seizure of a bearing and capable of dispensing with replacement of the bearing without increasing a manufacturing cost. Ž<P>SOLUTION: The variable flywheel 1 is provided with a drive plate 3 fixed on a crankshaft 2 of an engine, a driven plate 7 rotatably attached to the crankshaft 2 through the bearing 4 and having a weight part 6, and a wet clutch 9 connecting and disconnecting the drive plate 3 and the driven plate 7 by oil from a hydraulic source 8. The wet clutch 9 is arranged on an outer peripheral side compared to the bearing 4, and an oil passage 11 extended to the wet clutch 9 from the hydraulic source 8 through the inside of the crankshaft 2 is formed so that the oil flowing through the oil passage 11 is brought into contact with the bearing 4.
