Abstract: A hinge mechanism and a foldable electronic device are provided. The hinge mechanism is disposed in a foldable electronic device. When one rotation portion of the foldable electronic device moves, the hinge mechanism drives the other rotation portion to move. The hinge mechanism includes a fastening support, a transmission assembly, two first transmission shafts, a clamping assembly, and a first elastic portion. The fastening support is configured to be fastened to a base of the foldable electronic device, and the fastening support is coupled to the first transmission shaft to limit relative positions of the first transmission shaft and the fastening support. The first transmission shaft is coupled to the clamping assembly and the first elastic portion. The first elastic portion provides an elastic force for the clamping assembly such that friction between the clamping assembly and the transmission assembly generates damping.
