Abstract: A hinge mechanism includes a shaft (1), at least one cam follower (12), a cam (2), a washer (3) and an elastic member (4). Each cam follower has a projection (120) connected to the shaft. The cam has a cam surface (24) defined thereon. The shaft runs through the cam, the washer and the elastic member, in turn. The cam surface of the cam faces the projection of each cam follower, and the cam abuts the cam follower, due to the spring force generated by the elastic member. The washer and the cam are magnetic, the facing portions thereof having the same polarity. As a result of the repulsive magnetic force between the cam and washer, the hinge mechanism generates a smaller friction therebetween, so the waste of energy is very small. The present hinge mechanism can be used in foldable electronic devices.
