PROBLEM TO BE SOLVED: To provide a hinge structure allowing a boss to move in the axial direction and preventing a rattle motion of a first case and a second case using a hinge unit regulating an angle. SOLUTION: A cylindrical case 45 is arranged in a fixing part 46, and a shaft 34 is inserted into a shaft core part of the cylindrical case 45. Further, an engaging recessed part 51 slidable with an engaging projecting part 49 provided protrudedly in the cylindrical case 45 is formed on an outer peripheral face of a slide cam 38, which can slide in the axial direction but cannot rotate for the cylindrical case 45. Consequently, a rattle motion caused when a lid 20 is rotated is eliminated by merely attaching the cylindrical case 45 to the fixing part 46 by sliding the slide cam 38 assembled integrally as the hinge unit 10 in the axial direction for the cylindrical case 45. As a result, the slide of the slide cam 38 in the axial direction is guaranteed by the hinge unit 10 itself, and the rattle motion in the direction of rotation is absorbed.
