Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent mutual separation in axial directions of a bottom surface of a mirror housing and a support face of a base of a central shaft.SOLUTION: A hinge structure 1 is used in a door mirror unit of an automobile including a central shaft 2, and a mirror housing 3 disposed so it can revolve around its periphery. A bottom surface 4 of the mirror housing 3 is supported on a support face 5 of a base of the central shaft 2; it includes a first cam pattern 6 and a second cam pattern 7 cooperatively determining a predetermined angle position between the central shaft 2 corresponding to a protruding position of the mirror housing 3 and the mirror housing 3; the first cam pattern 6 is supported in a side separated away from the support face 5 of the mirror housing 3; and the second cam pattern 7 is rotatively joined and connected to the central shaft 2 so it can move in the axial direction. |
