A backrest recline adjustment assembly 2 includes a stationary seat 3, a rotary seat 4, and a driving component 5. The stationary seat is connected to a stroller frame 8, and is provided with a first positioning unit 31. The rotary seat is connected to a backrest unit 9 and has a second positioning unit 41, a groove 42 formed thereon, and a first cam surface (421, figure 7) formed in the groove. The driving component is disposed in the groove of the rotary seat and provided with a second cam surface 51. The driving component is movable to drive sliding movement of the second cam surface relative to the first cam surface, thereby moving the rotary seat against biasing action of a resilient component 22 from a securing position (figure 5), where the rotary seat is positioned relative to the stationary seat, to a releasing position (figure 9), where the rotary seat is rotatable relative to the stationary seat. A control unit 6 may be attached to the backrest unit so as to move the driving component to either side of the stroller frame, thus allowing single-handed recline adjustment.
