<p>The object is to provide an automatic operating apparatus for a friction clutch which apparatus performs the disconnection of the clutch of a transmission by the assistance of the accumulated load in a load accumulating means which can perform the accumulation and the release of the load by a simple mechanism. In the automatic clutch operating apparatus having a reduction means 9, 13 to reduce the forward rotating force of a motor 1 and a movement conversion means 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 accumulating means 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 comprising a crank arm 10, a piston rod 4a, a link 21 which is rotatably connected with a load accumulating means 16, 18 through a first connecting portion 20, and a second connecting portion 12 to rotatably connect these members with each other. <IMAGE></p> |
