In a hinge device 1, a door-side mounting member 6 is rotatably connected to a housing-side mounting member 3 via an inner link 4 and an outer link 5. To prevent the inner link 4 and the outer link 5 from being rattled, one protrusion 72 of a torsion coil spring 7 as a rotationally biasing mechanism is pressed against one side plate 41 of the inner link 4 via a cam member 91 and the other protrusion 73 of the torsion coil spring 7 is pressed against the other side plate 52 of the outer link 5.
