Abstract: An automatic clutch operating control apparatus which can rapidly perform the disconnection of a friction clutch of a transmission by the assistance of the accumulated load in a coil spring. Comprising a motor 4 rotatable forward and backward; reduction means 27, 23 for reducing the rotation of the motor 4; movement conversion means 19, 21, 15, 9 for converting the rotation of the motor to the axial movement of a piston rod 6; a hydraulic master cylinder 3 including the piston rod 6 for supplying working oil into a friction clutch to compress the spring in the clutch so that the clutch will be disconnected; a coil spring 31 provided on the piston rod 6 of the hydraulic master cylinder 3 so as to accumulate the load by the compression due to the repulsive force of the spring in the clutch when the motor 4 is rotated backward to connect the clutch and so as to release the accumulated load when the motor 4 is rotated forward.
