ABSTRACT:
A baby carriage has lateral walls along its seat section. These lateral or side walls are divided into first and second side wall panels (50, 51) which are normally contiguous with each other to extend longitudinally of the baby carriage when the carriage is unfolded. The first and second panels are turnably interconnected by a pivot shaft (13) positioned between the upper and lower edges of the side walls so that the panels of a pair are displaceable relative to each other axially of the pivot shaft when the panels are rotated. When the first and second panels are turned around the axis of the pivot shaft, they partly overlap each other while they are guided by spirally inclined surfaces (81, 88) formed around the pivot shaft and inclined surfaces (82, 90) formed on end edges of the side wall panels for folding these panels simultaneously with the folding of the baby carriage.
