Abstract
A lateral foldable children's carriage comprises a frame body and wheels arranged below the frame body. The frame body comprises side brackets on two sides. The side brackets comprise a bracket of rear wheels, a handgrip that is rotatablely connected to the upper end of the bracket of rear wheels and a backrest rod that is arranged on the frame body. A back cross support bracket is arranged between the two side brackets. The back cross support bracket comprises a first component and a second component which are crossly provided. The backrest rod is supported by the back cross support bracket. The first component comprises a first upper connecting rod and a first lower connecting rod. The second component comprises a second upper connecting rod and a second lower connecting rod. The first upper connecting rod and the second upper connecting rod are rotatablely connected by a rotary shaft.
