Abstract
A coupling device includes an input member, an output shaft coaxial with the input member, and a clutch mechanism that includes a plate disposed at the side of the input member and a disc disposed at the side of the output shaft. The clutch mechanism transmits rotational torque of the input member by frictional engagement between the plate and the disc. A disc supporting member is disposed between the clutch mechanism and the output shaft, and supports the disc. An actuator is adapted to engage the plate with the disc, and a transforming device moves the disc supporting member so as to engage the disc with the plate when the rotational torque of the disc supporting member differs from the rotational torque of the output shaft.
