Kind Code:
A1
Abstract:
A relative rotation prevention structure for preventing relative rotation of a screw having a threaded section with respect to a counterpart member, said relative rotation prevention structure being equipped with: a counterpart-side displacement section formed in advance on the counterpart member and capable of displacement in the axial direction or the radial direction; and a screw-side deformation accommodation section that is formed on the screw and deforms when pressed into the counterpart-side deformation section by means of fastening force and, due to that deformation, produces a screw-side displacement section that is displaced in the axial direction or the radial direction.
