ABSTRACT:
A lock-up torque converter for an automatic transmission includes a pump fixedly connected to a crankshaft of the internal combustion engine and a converter cover connected to a converter output shaft during a lock-up condition. A shock absorbing member connects the pump and the converter cover to be elastic in the rotating direction of the converter output shaft. Accordingly, both fluctuations of the engine speed and of the output shaft speed are absorbed by the pump and the converter cover, respectively and therefore the torsional vibrations and the noises generated in the passenger compartment are largely suppressed.
