    • Provided is a loosening preventive structure for a bolt and nut, comprising a bolt, a nut member to be threadably engaged with the bolt and a lock nut. Said nut member has a lock nut engaging section made in a tapering shape extending axially toward one end thereof. The lock nut engaging section includes a male thread defined in an exterior circumferential wall in the identical or the inverse threading direction relative to a female thread defined in the interior circumferential wall and also includes a slit extending axially toward the one end thereof.
    • 提供一种用于螺栓和螺母的松动防止结构,包括螺栓,与螺栓螺纹接合的螺母构件和锁紧螺母。 所述螺母构件具有锁定螺母接合部分,其形成为沿其一端轴向延伸的锥形形状。 锁紧螺母接合部分包括一个外螺纹,该外螺纹限定在外圆周壁上,该外螺纹相对于在内周壁中限定的阴螺纹相同或相反的螺纹方向,并且还包括沿其一端轴向延伸的狭缝。

    • A double nut is provided in which a flange nut and an insert nut are coupled. The flange nut has a longitudinal axis and has, in an end region facing the insert nut, a stop surface and a wall surface. The insert nut has a longitudinal axis and has at least one snap element in an end region facing the flange nut. The stop surface extends over the at least one snap element radially in the direction of the longitudinal axis of the flange nut. The flange nut has a guide surface in the end region facing the insert nut which is disposed closer to the longitudinal axis of the flange nut than the wall surface.
    • 提供了一个双螺母,其中法兰螺母和插入螺母联接在一起。 凸缘螺母具有纵向轴线,并且在面向插入螺母的端部区域中具有止动表面和壁表面。 插入螺母具有纵向轴线并且在面向凸缘螺母的端部区域中具有至少一个卡扣元件。 止动表面在法兰螺母的纵向轴线的方向上沿着至少一个卡扣元件径向延伸。 凸缘螺母在末端区域中具有面向插入螺母的引导表面,该引导表面比壁面更靠近凸缘螺母的纵向轴线设置。
