Abstract
In a nut disengagement prevention structure, a bolt has an external thread. A nut which is thread on the bolt has an internal thread. A thread portion which is the closest to a leading end of the bolt has a first minor diameter. Any other portion of the thread of the bolt has a second minor diameter which is smaller than the first minor diameter. The second minor diameter is substantially identical with a minor diameter of the internal thread of the nut.
