To provide a controlling unit of a clutch capable of precisely compensating wear of a clutch facing.

In the controlling unit of the clutch used for vehicles varying a clutching state between a flywheel 21 and clutch disk 23, when a first condition is formed, a controlling means controls operation of an actuator so as to increase an axial distance between a diaphragm spring and pressure plate in an adjusting mechanism. When a second condition different from the first condition is formed, the adjusting mechanism controls operation of the actuator so as to decrease an axial distance between the diaphragm spring and pressure plate.
