A baby carriage comprises a body frame including a pair of longitudinal side frame members, a seat hammock including a backrest sheet portion, a backside support, and an upper end connecting member. The backside support includes backside string members extending so as to support the backrest sheet portion from the back side such that it can be reclined. The upper end connecting member comprises an upper end string member extending along the whole width of the backrest sheet portion at the upper end in a width direction and having both ends connected to the pair of longitudinal side frame members. A length of the upper end connecting member is selected such that it is in an unloaded loose state until a reclined angle of the backrest sheet portion reaches a predetermined value and it is in a loaded tense state while the reclined angle of the backrest sheet portion ranges from the predetermined value to the maximum reclined angle to prohibit backward movement of the upper end portion of the backrest sheet portion.
