A foot pedal is located at a rear and lower portion of the automotive vehicle in an accessible position. The foot pedal is connected by actuating means to lifting means for lifting the back door in such a manner that the back door can rotate around the upper edge thereof to be opened. A door-lock release device is actuated in response to operation of the lifting means to release the lock of a locking device. The actuating means includes means for disconnecting the linkage between the lifting means and the foot pedal so that operation of the foot pedal cannot be transmitted to the actuating means.
