Abstract
A foldable baby carriage or infant carrier comprises a pair of slide guide rods, a pair of sliders slidable on the slide guide rods, a pair of front legs turnably connected at the upper end thereof to the sliders, a pair of rear legs turnably connected to the intermediate portions of the front legs, a pair of support angle bars turnably connected at one of their respective ends to the intermediate portions of the rear legs and at the other ends thereof to the lower ends of the slide guide rods, and a pair of foldable operative connecting rods which are turnably connected in such a manner as to connect the above-mentioned intermediate portions to the slide guide rods at positions spaced a predetermined distance from the lower ends thereof. During the folding operation, the various connecting portions turn while the sliders slide on the slide guide rods. In the folded state, the support angle bars overlap the slide guide rods, so that the overall height has been decreased.
