The present invention relates to a fastening mechanism having unfastening prevention features. A cross-shaped cut portion is formed at the end of a fastening member for fixing two objects, a nut portion is fastened to the outer peripheral surface of the cut portion to fix the fastening member, a fixing screw is input into the fastening member to be screwed in the vicinity of the cut portion, the fixing screw is inserted into the cut portion, the cut portion is expanded, and unfastening is suppressed by close contact between the threads of the nut portion and the cut portion. According to the present invention, a fastening member in which a nut portion is fastened to an outer screw of the end to penetrate two objects or an outer screw fastened to a nut portion formed in one of the two objects is provided, the outer screw is formed of a cut portion split in a cross shape, the fastening member is provided with a passage connected to the cut portion at the inner center thereof, an inner screw is formed to be close to the cut portion at the end of the passage, the passage is provided with a fixing screw fastened to the inner screw, the cut portion gets wider while the thread of the fixing screw penetrates into the inner corner of the cut portion, and adhesion with the nut portion is enhanced. |
