Abstract
An automatic clutch device includes an axial force generating mechanism including an electric motor arranged adjacent to the outer periphery of an end of an input shaft of a transmission, and a rotation-linear motion conversion mechanism for converting the rotation of the rotor of the electric motor to a linear motion of a release bearing. The rotation-linear motion conversion mechanism includes plural annular cam plates arranged in tandem on the input shaft, and torque cam mechanisms each disposed between each opposed pair of cam plates, for reduced size and improved responsiveness of the automatic clutch device.
