摘要： A free-stop hinge apparatus employed in a folding-type mobile terminal preferably includes: a hinge housing; a driving part for providing a free-stop operation, which is received in the hinge housing. A hinge shaft restrains the driving part in the hinge housing, and the driving part includes a rotating driving actuating cam and a driven sliding cam slides according to rotation of the driving actuating cam. The driving actuating cam includes an inner cam formed on one surface of a body, and an outer cam confronting the inner cam, and the driven sliding cam includes an inner valley which is disposed to confront the inner cam and slides together with the inner cam, and an outer valley which is disposed to confront the outer cam and slides together with the outer cam.
