An X-shaped folding device of a baby stroller is connected between the front and rear wheel frames of the stroller and includes a pair of front rods pivotably connected to the front wheel frame and a pair of rear rods pivotably connected to the rear wheel frame. The rear rods are crossly and pivotably connected to the front rods. A link device is connected to the pivotable member on the pivotal point of the two rear rods. The X-shaped folding device is folded by lifting the link device to folding the baby stroller, and is unfolded by pressing the link device. The link device further locks the folding device to prevent folding of the X-shaped folding device.
