Abstract
The utility model is a front wheel rotating and positioning device for a baby carriage. A movable positioning rod is arranged between a wheelset and a wheel seat, and is provided with three moving positions. A first position makes the wheelset at the state of directional rotation. A second position makes the wheelset at the wheelset at the state of free rotation in the wheel seat. A third position makes the wheelset break away from the wheel seat. Thus, the movable positions enable a user to select rotation or orientation for the wheelset easily, and assemble or dismantle the wheeelset in a simple way, so rotation of the baby carriage becomes more steady and smooth, and the baby carriage will not be out of control due to a outside force or a barrier and cause inappropriate rotation or positioning, so as to ensure the safe use and convenient operation of the baby carriage.
