Abstract: A baby carriage having a pair of front legs and a pair of rear legs. The pair of rear legs each have an angle bar pivotally connected thereto while the angle bar has a pusher rod pivotally connected to the other end thereof. With the baby carriage in the opened state, the angle bar is substantially in line with the associated pusher rod body. With the baby carriage in the closed state, the pusher bar body and the associated angle bar are in bent relation to each other, thus reducing the vertical dimension of the baby carriage. Further, in response to the turning movement of the angle bars relative to the rear legs, both the longitudinal and the transverse spacings between the front and rear legs are reduced. In this manner, the baby carriage is folded.
