A collapsible baby carriage has a main framework including a pair of right and left main rods, a pair of right and left auxiliary rods pivotally connected to the intermediate portions of the main rods, and a plurality of sets of bendable connecting rods installed between the pair of main rods and between the pair of auxiliary rods. The main rods are disposed to extend from the rear upper region to the front lower region, with their upper portions serving as push rods and their lower portions serving as front legs. The auxiliary rods extend rearwardly downwardly from their respective pivots to serve as rear legs. Of the plurality of sets of connecting rods, the sets provided for the main rods are connected to first rods which transmit their bending motion, whereby the spacing between the main rods is changed. This spacing changing motion is operatively effected through second and third rods with the rotation of the auxiliary rods relative to the main rods and with the motion for changing the spacing between the auxiliary rods. With this arrangement, a vertically extending elongated collapsed state can be obtained.
