Abstract
A hinge device includes a shaft, a rotary cam, a fixed cam, and an elastic part that causes a side surface of the rotary cam to contact a side surface of the fixed cam. The side surface of the rotary cam includes a rotation-side reference surface, a rotation-side lower surface part, a rotation-side higher surface part, and an engaging recess. The side surface of the fixed cam includes a fixed-side reference surface, a fixed-side higher surface part, a fixed-side lower surface part, and an engaging protrusion. When the rotation-side lower surface part engages the fixed-side higher surface part, the engaging recess engages the engaging protrusion. When the rotation-side lower surface part is disengaged from the fixed-side higher surface part, the fixed-side higher surface part is in sliding contact with the rotation-side reference surface and the engaging protrusion is in sliding contact with the rotation-side higher surface part.
