Vibration damping equipment for torsional damper, including a low rigidity member

摘要

A vibration damping equipment for a torsional damper comprises a hub plate, side plates, a torsion spring, a friction block, and low rigidity members. Each low rigidity member is interposed between the hub plate and each friction block to be adjacent to each other through a partition of the hub plate. The low rigidity members are connected to each other on at least one axial side of the partition.
