PURPOSE: To inhibit an increase in a predetermined angle in a damper mechanism not activating a friction mechanism within the predetermined angle range. CONSTITUTION: A clutch disc assembly 1 is provided with an input rotation body 2 a spline hub 3 a damper part 4 a large friction mechanism 13 a friction inhibition mechanism and an elastic member 104. The spline hub 3 is disposed relatively rotatably with the input rotation body 2 and a torque is inputted from the input rotation body to the spline hub 3. The damper part 4 is a mechanism for connecting the input rotation body 2 and the spline hub 3 in a rotation direction. The large friction mechanism 13 can generate a friction when the input rotation body 2 and the spline hub are relatively rotated. The friction inhibition mechanism is a rotation direction gap Θ ACp not operating the large friction mechanism within a predetermined angle. The elastic member 104 is a member for relieving an impact of the members butting to each other at an end of the predetermined angle.
