A direction changeable stroller comprises a frame unit that includes a side leg frame and a push handle pivotable between front and rear positions. The side leg frame includes front and rear leg tubes, and front and rear wheel assemblies. Each of the front and rear wheel assemblies includes a wheel seat and a wheel. Each of the wheel seats includes a fixed portion connected fixedly to a corresponding one of the front and rear leg tubes, and a rotating portion connected pivotably to the fixed portion. The side leg frame further includes an automatic direction-limiting mechanism connected to the push handle such that, when the push handle is at a selected one of the front and rear positions, relative rotation between the fixed portion and the rotating portion of a corresponding one of the front and rear wheel seats is prevented. |
