Precursor of a cathode active material for a lithium secondary battery, cathode active material, method for manufacturing the cathode active material, and lithium secondary battery including the cathode active material

A side view mirror having a rotatable housing comprises a cover plate mounted on an exterior of a vehicle body, wherein an inside and outside of the cover plate are divided based on the vehicle body. A stay includes a lever disposed at an inner side of the cover plate. An up/down/left/right angle adjusting part is integrated with a connection bar, connected to the lever through the connection bar, and configured to be movable in up/down and left/right directions with respect to an outer surface of the cover plate. A folding supporting part is integrated with the up/down/left/right angle adjusting part at the outer surface of the up/down/left/right angle adjusting part and connected to the mirror-integrated housing. A mirror-integrated housing is foldably or unfoldably coupled with the folding supporting part, and an angle of the mirror-integrated housing is adjusted in up/down and left/right directions by the up/down/left/right angle adjusting part.
