摘要： PURPOSE: An automatically foldable side mirror assembly is provided to enable a driver or passenger from getting off while looking at the rear by enabling a driver to look at the rear when a main side mirror is folded and a dead space when the main side mirror is unfolded. CONSTITUTION: An automatically foldable side mirror assembly includes a mirror(20) for a dead space. The mirror for the dead space is rotated between a first position and a second position using the rotation force of a drive motor of the automatically foldable side mirror. In the first position, the mirror for the dead space monitors the dead space when the side mirror is unfolded. In the second position, the mirror for the dead space monitors the rear of the vehicle when the side mirror is folded.
