Abstract
A hinge devicecomprises a damper hingeand a gravity hinge. The gravity hingecomprises a rotational force imparting mechanismfor converting gravity of the doorto rotational force to a closing direction when the doorrotates to the closing direction. The damper hingecomprises a damper mechanismfor reducing the rotational force to the closing direction of the door. The damper mechanismincludes a linear damperdisposed to the first hinge memberand a first cam memberand includes a second cam memberdisposed to the second hinge member. The linear damperis positioned far from the shaft memberin an orthogonal direction to a shaft line of the shaft memberand is positioned along the shaft member. When the doorrotates to the closing direction and goes down, the linear damperis shortened along with a cam action of the first cam memberand the second cam member
