PURPOSE:To enable engine vibration to be absorbed effectively, by specifying the ratio of moment inertia on drive side to that on driven side with regard to a torque fluctuation absorbing unit installed between a drive member and a driven member. CONSTITUTION:The moment of inertia J1 on drive side is calculated by including rotary members, drive members 13, 14, 16, 17, a ring gear 15, bolts 12, 30, a pin 18, a thrust plate 26, a conical spring washer 28, a washer 29 etc. of an engine including a drive shaft 11. On the other hand, the moment of inertia J2 on driven side is calculated by including a flywheel 21, a driven plate 20, a bolt 31, a frictional member 22, a driven disc 23, a conical spring washer 24, a clutch cover 41 etc. And ratio A (J1/J2) between both moments of inertia J1, J2 is set in a range from 0.7-1.4. As a result, a vibration absorbing unit with a low resonance frequency f can be obtained. |
