DAMPER MECHANISM

WIPO Patent Application WO/2011/055442

A1

Disclosed is a damper mechanism (100) wherein small torque variations generate a small hysteresis torque due to pressure contact between a radial plate (153) and first friction zones (126a) when inputting torque into the damper mechanism (100). As a result, it is possible to damp the small torque variations between the radial plate (153) and the first friction zones (126a) within the damper mechanism (100), and output the damped torque variations to an input shaft. Furthermore, the configuration is such that the larger the torsional angle between an annular plate (126) and the radial plate (153) along the relative rotational direction, the larger the coefficient of friction between both plates. Therefore, even if the torque variations becomes large, it is possible to generate hysteresis torque corresponding to the size of the torque variation.
