Patent abstract

A door opening and closing apparatus has a motor, a door latch and a power generation mechanism. When the voltage of the battery is below a level needed to drive the electric actuator, a predetermined manipulation of the power generation mechanism generates the power needed to drive the motor. Therefore, when the voltage of a battery that supplies electric power to the electric actuator is below a level needed to drive the electric actuator, the door opens.
