Abstract: A folding device for connecting legs of a highchair includes first and second folding members, a toothed wheel, and an actuator. The first folding member is formed with a positioning groove, and the second folding member is formed with a position limiting unit. The toothed wheel includes a wheel body that is disposed between the first and second folding members and that has a periphery provided with a primary tooth engaging the positioning groove. The primary tooth engages the position limiting unit to lock the second folding member from movement relative to the first folding member when the second folding member is at an expanded position. The actuator is operated to release the second folding member from the locking action of the toothed wheel when moving the second folding member back to a folded position.
