ABSTRACT:
A stoppage-maintaining device for maintaining a baby carriage either in a folded or an unfolded state. The handle bar is pivotally connected to a rear leg by a pivoting stoppage-maintaining bar. The stoppage-maintaining bar has two concave grooves on two surfaces which are alternately engageable, as the bar rotates, with a protrusion on an upper end of a stopper sliding on the rear leg. Also, extending upwardly from the stopper is an engagement plate which, when overlapped with an elastic plate on the rear leg, prevents the rotation of the stoppage-maintaining bar from its unfolded state. The engagement plate is biased toward the elastic plate.
