PROBLEM TO BE SOLVED: To provide a sub-damper unit and clutch disk assembly capable of attaining space saving in a radial direction of a circle around a rotation axis. SOLUTION: The clutch disk assembly 1 comprises an operating plate 30, a fixed plate 9, a torsion spring 7, and a third hysteresis torque generation mechanism 61. A coiled wave spring 36 in the third hysteresis generation mechanism 61 is formed by interconnecting a plurality of waved annular spring materials in the direction of the rotation axis.
