Claim:
A folding device adapted for interconnecting foldably first and second legs of a highchair, said folding device comprising: a first folding member adapted to be connected to the first leg and formed with at least one positioning groove; a second folding member adapted to be connected to the second leg and formed with a position limiting unit that has a first contact portion and a second contact portion adjacent to said first contact portion, said second contact portion forming a step with said first contact portion and being indented relative to said first contact portion; a toothed wheel including a wheel body that is disposed between said first and second folding members and that has a periphery provided with at least one primary tooth, a portion of said primary tooth being received in said positioning groove to arrest rotation of said wheel body relative to said first folding member; a spring disposed between said wheel body and said first folding member; and an actuator disposed on one side of said wheel body opposite to said spring and accessible externally of said second folding member; said second folding member being rotatable relative to an assembly of said first folding member and said toothed wheel between a folded position, where said primary tooth of said wheel body abuts against said first contact portion of said position limiting unit, and an expanded position, where said primary tooth of said wheel body abuts against said second contact portion of said position limiting unit; wherein said actuator is operable to move said primary tooth of said wheel body away from said second contact portion of said position limiting unit against urging action of said spring to permit movement of said second folding member from the expanded position back to the folded position.
