PROBLEM TO BE SOLVED: To improve torsion characteristic of a split type fly wheel by making the damper characteristic of the split type fly wheel with a torsional damper multistage and enhancing an integrated spring constant in order with increasing the mutual angle of torsion between the half-bodies of the fly wheel. SOLUTION: The first spring and the second spring having a greater play than that of the first are interposed in parallel between one half-body of fly wheel IT and a control plate 1, and a frictional connecting mechanism J and the preliminary compressed third spring are interposed in parallel between the control plate 1 and the other half-body of fly wheel IE. When the mutual angle of torsion between the half-bodies IE, IT, which corresponds to a play of the second spring isθ2 , the spring constant of the first spring is K1 , the pre-compressing force of the third spring is P, the frictional connecting force of the frictional connecting mechanism J is Fr , the following equation is obtained: K1 .θ2≈P+Fr .
