The object is to provide a small-sized automatic operating apparatus for a friction clutch. In an automatic operating apparatus 1 for a friction clutch in which the rotation of a motor 2 is reduced by a reduction mechanism 3 to rotate a crank 4, thereby axially moving an output rod 6 for connecting and disconnecting a friction clutch, a spring type accumulator 7 provided immovably on the casing 8 is connected with a crank 4 through a link 5. During connection of the friction clutch, the accumulator 7 accumulates the force received through the crank 4 and the link 5 from the output rod 6 axially moving in the direction of the arrow "a' by receiving the pushing force of a piston rod in a hydraulic cylinder. During disconnection of the friction clutch, the accumulator 7 releases the accumulated force through the link 5 into the crank 4, thereby aiding the axial movement of the output rod 6 in the direction of the arrow "b'. Consequently, it is not required to make a space for swaying of the accumulator 7, as differed from the case of the conventional automatic clutch operating apparatus. As a result, it becomes possible to constitute the automatic operating apparatus 1 for a friction clutch in a smaller size.
