Abstract: An improved apparatus for opening and closing a door including a hydraulic hinge and a spring-type hinge is provided. The hydraulic hinge includes a rotary member having a first housing, a piston guide placed inside the first housing, a rotary shaft disposed inside the piston guide and a piston screwed with the rotary shaft, and a fixed member having a second housing, a cylinder placed inside the second housing and having an oil outlet penetrating the cylinder for allowing oil to pass through the oil outlet, an outflow part formed on the top surface of the cylinder and having a plurality of support protrusions, a head mounted on the top surface of the cylinder and an adjusting bolt screwed with the head such an oil circulating passage is formed in the fixed member. The spring-type hinge includes a spring for closing an opened door by compressive tension and an elevation part rotatably elevated while being rotated, the elevation part having a spring fixing part formed on the top surface thereof for fixing the lower end of the spring.
