Abstract: A stroller push cart (1) for a young infant, including an infant carrier (2) and a frame (3) equipped with wheels (23) on which the infant carrier can be mounted. The infant carrier (2) includes a shell (5) and a handle (6) and presents a relatively rigid structure. The ends of the handle (6) are mounted in a pivoting fashion on opposite sides of the infant carrier (2). Assembly and locking mechanisms are arranged in part on the infant carrier (2) and in part on the frame (3). The disembly and locking mechanisms selectively interconnect to permit detachable installation of the infant carrier (2) on the frame (3). The frame (3) includes pivotally connected supports (20, 21) and is without a handle.
