Abstract
A stroller is provided with a handle having a horizontal middle part and two side pipes. The two side pipes are connected to the horizontal middle part by gear trains so as to be turnable about axes perpendicular to an axis of the horizontal middle part, respectively. A folding part operating mechanism is incorporated into the horizontal middle part of the handle. The side pipes can be folded and unfolded relative to the horizontal middle part by turning the horizontal middle part about its axis.
