An improved doll-carriage having a retaining and adjusting mechanism which makes assembly and operation easier. The retaining and adjusting mechanism comprises a retaining piece and an adjusting piece mounted in a fixed relation to the retaining piece. The retaining piece has a guide channel thereon for press-fittingly engaging with a corresponding rear support leg when the carriage is in an extended configuration. The adjusting piece has a protrusion with teeth and pins on an outer face thereof for engaging with corresponding teeth and holes provided in a cylindrical recess of the retaining piece. The adjusting piece is urged to bear against the retaining piece by a spring received within a receiving recess formed on the adjusting piece and secured by a cover so that the adjusting piece is angle-adjustable in a limited manner. The retaining piece has an extension wing formed on a face proximate to the outer face of the adjusting piece which prevents any undesirable gap to be formed between the retaining piece and the adjusting piece.

In an improved doll-carriage of the type having a respective pair of front and rear support legs, a pair of linkages, a substantially U-shaped handle, a back seat linked to the handle, a pair of retaining pieces having inner and outer faces and an annular periphery, each securely attached at an end of the handle and pivotally connected to one end of a corresponding linkage for operably moving the front support legs via the linkages, a pair of adjusting pieces, each having an inner and an outer face and an annular periphery, fixed on end portions of the back seat for securing the back seat to said retaining pieces, a cover and a spring for urging each adjusting piece to bear against a corresponding retaining piece, the improvement comprising: on each retaining piece; an extension wing extending rearwardly from said retaining piece and substantially occupying a crotch between the retaining piece and the adjusting piece, the crotch being formed during relative movement therebetween said extension wing having a rearwardly and downwardly extending upper edge which intersects with a downwardly and forwardly extending lower edge; a cylindrical recess on the inner face of the retaining piece, having a plurality of first divided teeth on an annular periphery; and at least one arcuate-shaped adjustment hole formed therein; and on each adjusting piece: a substantially cylindrical protrusion on the outer face thereof, said cylindrical protrusion conforming to said cylindrical recess of said retaining piece and having a plurality of second divided teeth on an annular periphery thereof, said second divided teeth facing and forming a frictional engagement with said first divided teeth on said retaining piece; and a corresponding number of cylindrical adjustment pins in engagement with said adjustment hole for limiting an angular movement of said adjusting piece relative to said retaining piece.
