PROBLEM TO BE SOLVED: To provide a vibration resistant hinge for simplifying assembling by stopping processing of either tube part inner face of upper and lower blade plates and indirectly inserting a spring necessary for the tube part and related members. SOLUTION: The hinge forms the tube part by rounding one side of a flat plate, assembles the two blade plates providing the required number of attaching holes on the flat plate part continued to the tube part upward and downward, inserts and fixes part of a rotating shaft on the tube part of any one blade part, and rotatably and detachably fits the tube part of the other blade plate on a fixed shaft. A unit 11 comprising a cylinder 12, a plug 16, a spring 20 and an ornamental top 21 is mounted in the tube part 4 of the blade plate 2 fitted rotatably and detachably to the 26. The unit supports the shaft so that a gap between the tube parts 4 and 8 of the blade plates 2 and 6 juxtaposed upward and downward through the shaft is not directly contacted in normal movement. The vibration resistant hinge has a structure in which the unit absorbs movement of the shaft when the gap between the tube parts of the blade plates juxtaposed upward and downward through the shaft is in abnormal movement to contract or eliminate the gap.
