Abstract: An adjustment device of an auxiliary carry device connected to a baby stroller includes an expanding unit and a folding unit. The folding unit is connected to a board. The expanding unit has two cables, two links and a base. The two cables are connected to the baby stroller, and the two links are connected between the cables and the base connected to the board. The expanding unit makes the two links simultaneously be pivoted away from or toward each other. The folding unit is connected between the board and the expanding unit to pivot the base. The board is pivoted relative to the baby stroller to save space, and the cables provide cushion feature to the board.

Abstract: A seat rotating device for a baby stroller includes a rotation unit connected to an underside of the seat and two insertions on two sides of an underside of the rotation unit are inserted into a positioning unit. The rotation unit has a disk and the seat is connected to the disk. The disk has a plurality of positioning holes defined in a periphery thereof. The disk is pivotably connected to a base by a shaft extending through a center of the disk and the base. The base has two wings and the two insertions are inserted into the wings. Each wing has a biasing member inserted therein which his connected with a cable. The biasing member is inserted into one of the positioning holes to position the disk and the seat at an angle.
