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.

A baby carriage comprising: a seat structure; a pair of front leg bars; a pair of armrest bars; a pair of rear leg bars pivotably attached to upper ends of said front leg bars at the front ends of said armrest bars, and extending downwardly and rearwardly from said seat structure; a handle bar to which the rear ends of said armrest bars are pivotably mounted, said handle bar extending upwardly and rearwardly from said seat structure; at least one stoppage-maintaining bar swingably attached at a pivot point above a first end thereof to one of said rear leg bars and at a second end to said handle bar, said stoppage-maintaining bar having at least one concave groove formed therein; and at least one stopper slidably mounted on said one rear leg bar for movement in an axial direction of said rear leg bar along said rear leg bar and having an upper end surface and an engagement-stopper protrusion formed on said upper end surface thereof engagable with said at least one concave groove; said pair of front legs, said pair of rear legs, said pair of armrests, said handle bar, and said at least one stoppage-maintaining bar being pivotal relative to one another so that said baby carriage may be in one of a folded state and an unfolded state; wherein said stopper has an upper end further comprising: an elastic plate attached to said rear leg bar above said stopper upper end surface; and a stoppage-maintaining plate attached on said upper end surface of said stopper, said stoppage-maintaining plate extending of said stopper, said stoppage-maintaining bar than said engagement-stopper protrusion such that said stoppage-maintaining plate overlaps said elastic plate, and wherein when said stopper is moved axially along said rear leg away from said seat structure, an edge of said elastic plate facing said upper end surface of said stopper and an edge of said stopper-maintaining plate projecting away from said upper end surface of said stopper contact one another and maintain said stopper and said stoppage-maintaining bar a fixed distance from one another so that said engagement-stopper protrusion is disengaged from said at least one concave groove.
