The clutch disconnection/connection device further includes a clutch pedal stroke sensor for detecting magnitude of clutch pedal stroke(CPS), a clutch stroke sensor for detecting magnitude of clutch stroke(CS), and a controller for, based on output signals from the clutch pedal stroke sensorand the clutch stroke sensor, when the clutch pedal is stepped during automatic disconnection/connection operation in such a degree as corresponding to the actual clutch stroke(CS) state or thrusting the clutch to more disconnected state, discontinuing the automatic disconnection/connection operation and initiating the manual disconnection/connection operation.
