Abstract: A hinge device includes first and second leaves provided respectively with first and second knuckles coupled pivotally to each other, a torsion spring having an end connected to the second knuckle, cam co-rotatable with the first knuckle, and a cam follower disposed in the first knuckle and coupled to an opposite end of the torsion spring. The first knuckle and the cam are rotatable in a first rotational direction for driving the cam to engage the cam follower and for rotating the cam follower so as to twist the torsion spring. The cam follower can be driven by a restoring force of the torsion spring to rotate in a second rotational direction opposite to the first rotational direction to drive the cam and the first knuckle to rotate in the second rotational direction, and is operable to rotate in the first rotational direction for twisting the torsion spring.
