Abstract
A hinge device 1 comprises a damper hinge 2 and a gravity hinge 3. The gravity hinge 3 comprises a rotational force imparting mechanism 70 for converting gravity of the door 6 to rotational force to a closing direction when the door 6 rotates to the closing direction. The damper hinge 2 comprises a damper mechanism 30 for reducing the rotational force to the closing direction of the door 6. The damper mechanism 30 includes a linear damper 31 disposed to the first hinge member 10 and a first cam member 32 and includes a second cam member 35 disposed to the second hinge member 20. The linear damper 31 is positioned far from the shaft member 40 in an orthogonal direction to a shaft line of the shaft member 40 and is positioned along the shaft member 40. When the door 6 rotates to the closing direction and goes down, the linear damper 31 is shortened along with a cam action of the first cam member 32 and the second cam member 35.
