The present invention relates to a hinge apparatus for a door, and more particularly, to a separated type hinge apparatus with an automatic return function, in which a restoring device and a damping device are installed separately so that the overall length of the hinge apparatus is reduced, and thus the hinge apparatus may be buried less deeply. A separated type hinge apparatus comprises: an elastic casing; a first elastic member that provides a restoring force; a clutch device which is combined with one end of the first elastic member and controls the elastic force of the first elastic member to remain constant; a shaft penetratively combined through the clutch device in order to transmit a rotational force; and a spring fixing member which is coupled to the other end of the first elastic member and has a gear groove to control a spring elastic force.
