A device for automatically rocking a stroller. Winding structure includes a connecting rod, whose first end is eccentrically mounted to the spring structure and whose second end is equally eccentrically mounted to the wheel axle extension so that the forward movement of the stroller winds the spring structure. The rocking structure includes a rod whose far end is mounted eccentrically to the wheel axle extension and whose forward end is less eccentrically mounted to the spring structure to ensure that the rod assumes a reciprocating motion during the unwinding of the spring structure. The user switches from winding mode to rocking mode. In an alternative embodiment a first rod attached to the shaft includes a lever that assumes different positions, the different lever positions changing the degree to which a second rod is eccentrically mounted to the spring structure and determining whether the device is in winding or rocking mode.
