Abstract
A torque converter with a lockup damper is provided to improve the vibration damping function. The torque converter has the lockup device for mechanically connecting and disconnecting a front cover and a turbine , which includes a clutch mechanism and a damper mechanism. A friction generating mechanism is a mechanism that generates friction resistance when the lockup damper operates, and includes a friction washer , which constitutes a friction surface, and a micro twisting angle adjustment gap , which is arranged to prevent the friction washer from operating within a range of micro twisting angles.
