A folding device is configured at the bottom of rear leg frame and at the pivot between the rear leg frame and front leg frame of a high chair. The folding device allows a user to complete folding process by pressing a button at the bottom of the rear leg frame. When the button is pressed, a rotator in the housing of the folding device rotates correspondingly and drags connected steel wires to move horizontally inward. The other ends of the steel wires further connect to engaging parts at the pivots and engaging between the front leg frame and the rear leg frame and retract the engaging parts so that the rear leg frame disengages from and pivots about the front leg frame. The high chair may be folded with one-foot operation.

The high chair of claim 1, wherein the actuator is linked to the rotation part for rotating the rotation part to a release position relative to the housing, and when the rotation part rotates to the release position relative to the housing, the rotation part moves the engaging part to slide via the linking part and the engaging part disengages from the front leg frame. 3. The high chair of claim 2, wherein the front leg frame comprises a pivoting segment where the first end of the rear leg frame pivots to and the engaging part engages with, and when the rotation part moves the engaging part to slide via the linking part, the engaging part disengages from the pivoting segment. 4. The high chair of claim 3, wherein the pivoting segment of the front leg frame comprises a recess and the engaging part secures the rear leg frame at the unfolding position by engaging with the recess. 5. The high chair of claim 2, wherein the folding device further comprises a first elastic part connected between the engaging part and the rear leg frame for providing a restoring stress on the engaging part when the rotation part moves the engaging part to slide and disengage from the front leg frame. 6. The high chair of claim 1, wherein the folding device further comprises a cover rotatably mounted on the housing for covering over the button. 7. The high chair of claim 1, wherein the folding device further comprises a second elastic part connected between the button and the housing for providing a restoring stress on the button when the button moves along the first direction. 8. The high chair of claim 1, wherein the rotation part further comprises a ditch for containing the linking part when the button moves along the first direction and the rotation part rotates relative to the housing and rolls the linking part along a second direction into the ditch. 9. The high chair of claim 1, wherein the linking part is a steel wire. 10. The high chair of claim 1, wherein the linking part is configured within a tube of the rear leg frame. 11. The high chair of claim 1, wherein the folding device further comprises a spindle mounted on the first end of the rear leg frame and pivoting to the front leg frame, the engaging part mounted in the spindle and slidable to engage with the front leg frame by extending out of the spindle. 12.
