PROBLEM TO BE SOLVED: To set a first circumferential clearance and a second circumferential clearance to appropriate angles in the respective second stages. SOLUTION: A damper mechanism of a clutch disc assembly 1 is provided with an input rotor 2, an output rotor 3, a separation flange 6, a first spring 7, a second spring 8, and an intermediate plate 11. Torsion characteristic second stages where the second spring 8 is compressed in the rotation direction are present in a positive side where the input rotor 2 is twisted in the drive side in the rotation direction of the output rotor 3 and the negative side twisted in the inverse side respectively. The intermediate plate 11 is friction engaged with the input rotor 2 so as to slide in its rotation direction so as to constitute a large friction mechanism 13. Such a positive side second-stage clearance angleθACp is secured that, when the second spring 8 is actuated in the positive side second angle area, the second spring is prevented from actuating on the intermediate plate 11. In the negative side second angle area, the negative side second clearance angle can be secured similarly.
