A structure for swiveling and anchoring the front wheel of a tricycle includes an actuation assembly, which has a rotary knob located above an anchor dock to turn a driving disk that has sloped surfaces to move an anchor pin upwards to control release and latching of a wheel seat so that the front wheel of the tricycle may be swiveled freely or moved forwards in a constant direction. As the rotary knob is located above the driving disk, the latch condition of the tricycle frame is less likely to be released by incidental impact. Therefore improved safety may be achieved.
