A hinge device equipped with a resinous base hinge and a resinous arm hinge which rotatably engages the resinous base hinge via a rotating shaft, wherein: the resinous base hinge or the resinous arm hinge has the rotating shaft, while the other hinge has a rotating-shaft receiver for pivotally supporting the rotating shaft; and a biasing member positioned on the rotating-shaft side and a sliding body positioned on the rotating-shaft-receiver side are both interposed between the rotating shaft and the rotating-shaft receiver. Furthermore, the sliding body has a convexity on the outer-circumferential surface thereof, the periphery of the convexity has a notched section formed therein, and displacement occurs in a manner such that on the inner-circumference of the rotating-shaft receiver, the convexity is pressed toward and pushed into the biasing member side.
