A belt assembly is arranged on a back side of a backrest of a baby carriage, so that the angle of inclination of the backrest may be changed by adjusting of the length of the belt assembly. The belt assembly includes a first belt, a second belt, and a buckle which is attached to an end of the first belt and which has the second belt passing therethrough. The second belt has on its first major surface a plurality of engaging cavities. The buckle holds an operating member, which is cross-directionally or laterally movable across the second belt, and which is urged by a spring to move downwardly. The operating member is provided with engaging projections, which can selectively engage the engaging cavities. The length of the belt assembly is fixed when the engaging projections engage the engaging cavities, while the length of the belt assembly is rendered changeable when the former disengage from the latter. Thus, an adjusted length of the belt assembly can be reliably maintained by engagement of the engaging projections in the engaging cavaties.
