PROBLEM TO BE SOLVED: To provide a function to restrict an open angle of each wing portion to a hinge device coupled in a rotatable manner for two wing portions. SOLUTION: In a hinge device 10 having wing portions 12a and 12b coupled in a rotatable manner by a pivot 11, a restricting means 17 limiting the open angle of both the wing portions is provided at both the end portions of the rod 17a extended in a direction perpendicular to the pivot 11, and a restricting rod 17b extended in a direction parallel to the pivot is provided, each restricting rod is arranged to make the slide route 18 provided at both wing portion in a movable and inseparable manner; when both the wing portion has a predetermined open angle, they come to contact with a stop portion 18a at the pivot side where a slide route is formed; when the open angle becomes smaller, the slide route moves and comes into contact with a stop portion 18b formed at the opposite side of the pivot side stop portion 18a and the open angle becomes smaller to a predetermined value as a feature of this hinge device.
