A clutch plate g is arranged between the turbine b and the input case e on the other side and connected to the output shaft f, and is frictionally engaged with the input case e between the turbine b and the input case e. The clutch plate g and the turbine b are connected to each other so as to be relatively rotatable in the circumferential direction via a longitudinal coil spring h, and the clutch plate g is pressed against the input case e. There is also described a system in which torque fluctuations are absorbed by the spring h when the input case e and the turbine b are directly connected.
