A reversible mechanism disposed on a stroller, the stroller comprising a stroller frame and a reversible member pivoted to the stroller frame, the reversible mechanism locking the reversible member at different positions relative to the stroller frame and comprising:

• anchoring portions disposed on at least two different positions of the stroller frame;
• a sliding sleeve movably jacketing the reversible member, the sliding sleeve being selectively engaged with any one of the anchoring portions for locking the reversible member at the different positions relative to the stroller frame;
• and
• a release actuator movably disposed on the reversible member and linked with the sliding sleeve, the sliding sleeve being switched between a locking position and a releasing position with movement of the release actuator or being directly operated for locking or releasing the anchoring portion;
• wherein the reversible member comprises a U-shaped tube, a straight tube and a joint structure comprising a cutout portion, and the U-shaped tube is pivoted to the straight tube via the joint structure to make the U-shaped tube rotatable relative to the straight tube;
• wherein the release actuator comprises an operating portion, and the release actuator is disposed on the reversible member in such a manner that the operating portion is disposed in the cutout portion and is slidable along a lengthwise direction of the reversible member through operating the operating portion.
