A backrest angle adjusting device 30 adapted to a baby carriage includes a fixing base 31 and a driving base 32, wherein the fixing base is fixed on a frame 10, and the driving base is connected to a backrest 20 and capable of rotating with respect to the fixing base. The fixing base has at least two engaging grooves (fig 2, 310), wherein the engaging grooves are arranged in an arc shape to form a multi-stage structure. The driving base has a lock member (fig 2, 320) engaged with one of the engaging grooves (fig 2, 310). The engaging groove and the lock member are capable of engaging with each other at a predetermined angle, so as to lock the driving base 32 with respect to the fixing base 31. Accordingly, when the lock member disposed on the driving base is engaged with different engaging grooves of different stages, the angle of recline of the backrest with respect to the frame is different.
