PURPOSE:To improve durability and to reduce cost by interposing a sealing member between an inner ring and an outer ring in a rolling bearing, and interposing the resin whose friction coefficient is relatively large between the rolling bearing and one of the flywheels in a condition with tightening margin. CONSTITUTION:A torque transmission device is provided with two flywheels 2, 3 supported by a rolling bearing 4 in a relatively rotatable manner, and a buffer mechanism 5 to suppress the relative rotation is interposed therebetween. The first flywheel 2 is fixed to the crankshaft of the engine, while a friction clutch is fixed to the second flywheel 3, and a clutch disc is interposed therebetween. A rolling bearing 4 constituted by interposing a sealing member 43 consisting of an annular rubber to seal the space between an inner ring 41 and an outer ring 42. The outer circumferential surface and the edge surface of the outer ring 42 are covered by a pair of heat-insulating covers 6 which are formed in L-shaped section respectively. |
