PURPOSE: An opening/closing device of a door in a vehicle is provided to smoothly open and close the door without any interference by installing a cylinder barrel of a door check cylinder as a hinge type inside the door. CONSTITUTION: A compressor(1) and an air tank(2) are installed inside a vehicle. A hinge bracket having a hinge hole is screwed inside an inner panel of a door(5). A hinge pin to be protruded in a cylinder barrel of a door check cylinder(10) is inserted inside the hinge hole. A rod is protruded in front of the inner panel. A door check hinge having a hook is installed in a doorframe to be corresponding to the rod. The end of the rod is hinged in the hook of the door check hinge. A door lock cylinder(16) is installed in the back side of the hinge bracket. A rod of the door lock cylinder is connected between a door lock and an inner handle. By pulling the inner handle, the rod is connected with a pulling rod through a connecting rod. Solenoid valves are connected with air hoses to supply air to the door check cylinder and the door lock cylinder. A solenoid valve is installed in an inlet of an air tank to flow air only into the air tank. Solenoid valves are installed in outlet of the air tank in each door. A switch operating unit(3) having opening, closing and neutral ports controls each solenoid valve. Thereby, the installation cost is reduced and the door is opened smoothly.
