FRICTIONAL RESISTANCE GENERATING MECHANISM FOR REDUCING TORSIONAL VIBRATION DUE TO TORSIONAL FRICTION WHEN TWO ROTATING MEMBERS ROTATE RELATIVELY IN A VEHICLE

摘要

A friction resistance generation mechanism is disposed between two relatively rotatable members of a rotating mechanism. The mechanism includes an input side disk-like plate 32, output side disk-like plates 30 and 31, first friction shims 61A, and second friction shims 61B. The first friction shims 61A are frictionally engaged with the plates 30 and 31, and engaged in a manner that allows torque to be transmitted by way of a first rotational direction gap 79A to the plate 32. The second friction shims 61B are frictionally engaged with the plates 30 and 31, and engaged in a manner that allows torque to be transmitted to the plate 32 by way of a second rotational direction gap 79B with a different size than the first rotational direction gap 79A.
