Title: FASTENER, FASTENING STRUCTURE FOR FASTENER, HINGE STRUCTURE, AND MALE FASTENER
Abstract:
A fastening structure for a fastener, wherein a male screw is formed from a male screw head section, a male threaded section, and a male screw engaging section positioned closer to the male screw head section than the male threaded section. A female screw has a female threaded section, and a female screw engaging section formed to be closer to the male screw head section than the female threaded section. By screwing the male screw to the female screw, the male screw engaging section engages with the female screw engaging section and an engaging mechanism is configured wherein the mutually engaged state is maintained even if a relative rotation force acts in the loosening direction. As a result, it is possible to achieve anti-loosening effects with a simple structure.
