A fluid coupling power transmission having a lockup clutch, in which a housing is formed by the shell of a pump impeller and a front cover integrally connected to the shell, in which a turbine runner facing the pump impeller is arranged in the housing, and in which the lockup clutch is disposed in the housing for transmitting a torque selectively between the housing and an output member integrated with the turbine runner. The fluid coupling power transmission comprises: a damper mechanism including a rotational inertial mass made rotatable relative to the housing and selectively engageable with the lockup clutch, and elastic members arranged between the rotational inertial mass and a drive side member made rotatable together with the housing, and adapted to be compressed by the relative rotation of the rotational inertial mass and the drive side member; and a friction mechanism for establishing a sliding frictional force for suppressing the rotation of the rotational inertial mass relative to the drive side member if the relative rotation exceeds a predetermined angle.
A fluid coupling power transmission having a lockup clutch, in which a housing is formed by the shell of a pump impeller and a front cover integrally connected to said shell, in which a turbine runner facing said pump impeller is arranged in said housing, and in which said lockup clutch is disposed in said housing for transmitting torque selectively between said housing and an output member integrated with said turbine runner, comprising:
