<p>PROBLEM TO BE SOLVED: To check any drop in the initial reaction of damper rubber due to heat deterioration shrinkage as well as to make this damper rubber not to separate from a torque transfer pin, and besides, there is no crack occurring in the damper rubber even after long usage for months. SOLUTION: A peripheral part of damper rubber 31 is formed into a stepped peripheral part where an outer diametral size of an inner end face side colliding with an inner bottom face of a damper cover 30 is larger than that of an outer end face side being exposed on a tip side of this damper cover 30. In succession, a tip inner peripheral edge 30c of the damper cover 30 and a tip peripheral edge 32a of a torque transfer pin 32 both are made up into a section circular form each. A peripheral surface, a tip face of a large diametral part 37 and the tip peripheral edge 32a of the torque transfer pin 32 are all covered with the damper rubber 31. The peripheral part of an outer end of the damper rubber 31 is eccentrically positioned in a central part corresponding to a tip part of the torque transfer pin 32 and at the nearer side of an armature 33 than a tip of the damper cover 30.</p> |
