8 1 is the friction plate 2 and the right end surface of the recess 33 1 of the driven plate 33.
The spring seat 28 1 on the left side is pressed against the end surface on the right side of the recess 21 1 of No. 1 and is pressed by the step portion 30 1 of the first flywheel 5 located on the left side of the spring 28 to compress the spring 28. As a result, the first flywheel 5 and the friction plate 21 move relative to each other, and a frictional resistance is generated in the friction connecting portion 11, and the relative motion acts as a reciprocating motion with a change in torque. When the relative movement is in the direction opposite to the arrow A, the action is opposite to that described above. Therefore, when the vibration rotation is transmitted, the vibration damping action due to the friction resistance occurs in addition to the buffer action due to the spring.

Since the ring groove 5a is formed on the inner peripheral side of the friction surface 5b which is in contact with the friction ring 22 due to the damping action of No. 1, the friction ring 22 and the friction surface 5b are prevented from hitting each other and the required friction resistance is obtained.

In addition to the dynamic vibration damping effect by the flywheel, the vibration damping effect by friction can be added. Moreover, since the ring groove is provided on the inner circumference of the friction surface, it is possible to prevent uneven contact of the friction ring and to act as a grease holding groove to improve wear resistance. Further, since the first flywheel is made by press molding, it can be mass-produced at low cost, and since no cutting chips are generated unlike those obtained by cutting, a step for removing cutting chips is unnecessary.
