A stroller chassis includes a frame and a wheel that are connected to each other by a hinge defining a pivoting axis extending perpendicularly to the wheels axis. The chassis can also include a bearing for guiding the frame and the wheel in free rotation about the axis. The chassis can include two plates, each including an annular body substantially centered with respect to the pivoting axis and arranged externally around the bearing. The two annular bodies are connected rotatably about the pivoting axis to the frame and the wheel and define substantially planar surfaces on the plate surfaces, the planar surfaces being mutually adjoining along a plane that is transverse to the pivoting axis. The plates cooperate with one another through sliding and frictional contact. The Chassis can also include resilient member for pressing the annular bodies against each other to maintain contact between the planar surfaces.
