An automatic operating apparatus for a friction clutch is disclosed which apparatus performs the disconnection of the clutch of a transmission by the assistance of the accumulated load in a load accumulator which can perform the accumulation and the release of the load by a simple mechanism. In the automatic clutch operating apparatus having a reducer 9, 13 to reduce the forward rotating force of a motor 1 and a movement converter 10, 12 to make a piston rod 4a of a hydraulic master cylinder 2 move in the axial direction so as to disconnect the friction clutch, a link mechanism is constructed for accumulating the loads due to the rotating force of the motor 1 and the repulsive force of the clutch spring in the load accumulator 16, 18 when the motor 1 is rotated backward to connect the friction clutch and for releasing the accumulated loads when the motor 1 is rotated forward to disconnect the clutch. The link mechanism is formed as a toggle joint including a crank arm 10, a piston rod 4a, a link 21 which is rotatably connected with a load accumulator 16, 18 through a first connecting portion 20, and a second connecting portion 12 to rotatably connect these members with each other.
