Abstract: The retractable head lamp device includes a fixed bracket for fixing the device to the vehicle body, a movable bracket having a head lamp for positioning the head lamp between the retracted and projected positions, a drive mechanism having a motor to rotate the movable bracket relative to the fixed bracket. The device further includes a stopper member to define the retracted position of the movable bracket. The stopper member includes a threaded hole and the movable bracket includes a hole corresponding to the threaded hole of the stopper member for inserting a bolt into the holes to fix the relative position thereof during adjusting the relative position between the movable bracket and the drive mechanism so that the lines between the head lamp cover and the outer surface of the vehicle hood may be in a line.
