ABSTRACT:
In order to allow bending of members defining the cross-directional size of a frame of a foldaway baby carriage in association with movement of members forming side surfaces of the frame, side bars rotate with respect to front legs to draw up front leg sleeves through front leg rigid links. At this time, guide pins provided in the front legs are moved in spirally extending guide grooves which are formed in the front leg sleeves, so that the front leg sleeves rotate due to the spiral extension of the guide grooves. Thus, a front leg coupling link extending across the pair of front leg sleeves is bent about bend points. A similar structure is employed in relation to a rear leg coupling member extending across a pair of rear legs and a side bar coupling member extending across a pair of side bars.
