The invention provides a lower swing arm, a manufacturing method thereof and an automobile, and relates to the technical field of automobiles. A first through hole is formed in a main plate of the lower swing arm, a second through hole opposite to the first through hole is formed in a reinforcing plate, and the main plate comprises a first contraction part located on the outer edge of the first through hole, a first extension part located on the outer edge of the first contraction part and a first flanging extending out of the first through hole. The reinforcing plate comprises a second contraction part located on the outer edge of the second through hole, a second extension part located on the outer edge of the second contraction part and a second flange extending out of the second through hole, and the thickness of the second extension part and the thickness of the second flange are both smaller than the thickness of the second contraction part. And the free end of the first flange and the free end of the second flange are in contact and fastened connection. According to the lower swing arm, the manufacturing method of the lower swing arm and the automobile, the first turned-over edge and the second turned-over edge can be in contact and fastened connection, the manufacturing cost of the lower swing arm can be saved, and the weight of the lower swing arm can be reduced.
