An electric activating system for vehicle roofs and openable members in which an openable member is opened and closed by rotation of driving shafts provided on right and left sides. The system includes a motor which rotates the driving shafts via a reduction mechanism and switching relays which switch the rotational direction of the motor. Open and close command switches command the opening and closing of the openable member and a rotation synchronization sensor associated with the motor generates pulses synchronized with the rotation of the motor. A mechanical stopper limits the rotation of the driving shaft which is rotated via the reduction mechanism of the motor and a motor lock detecting means detects locking of the motor by detecting the pulse width generated by the rotation synchronization sensor. Also, an actuation stopping arrangement stops the actuation of an actuation device which supplies current to the motor if a signal is generated by the detection apparatus that detects locking of the motor.
