A collapsible baby carriage comprising a pair of front legs, a pair of rear legs, a pair of push rods, and a plurality of connecting links bendably installed between each pair of front legs, rear legs and push rods. The bending movements of these pluralities of connecting links are operatively associated with each other by link mechanisms. At least one of these pluralities of connecting links are upwardly bendable, so that when the bendable section of this plurality of upwardly bendable connecting links is lifted to allow the whole baby carriage to hang downwardly, the weight of the baby carriage acts to upwardly bend the connecting links, in operative association of which upward bending the other pluralities of connecting links are also bent, reducing the distances between the pair of front legs, the pair of rear legs and the pair of push rods, respectively, whereby the baby carriage is collapsed.
