Abstract
A motor vehicle is provided with a side door hinge mechanism having rotary center shafts, two rotatable arms and a door check mechanism. The rotary center shafts are supported at two positions on the rocking proximal end of the side door and at two positions on the side of the vehicle body. The first arm is rotatably connected at its opposite ends by a rotary center shaft on the side of the vehicle body and a rotary center shaft on the side of the door. The second arm is rotatably connected at its opposite ends to a rotary center shaft on the side of the vehicle body and a rotary center shaft on the side of the door and is in a plane parallel to and directly below the first arm. The door check mechanism is comprised of a torsion bar, a cam plate and a roller. The torsion bar is mounted to either the first or the second arm. The cam plate is mounted on a side door of the vehicle body. A roller is rotatably supported on the torsion bar and rotatably urged against the surface of the cam plate by a torsion force. A door check force is generated by lifting the surface of the cam plate.
