摘要： A lock nut is increased in locking effect by an increased frictional force produced due to deformation of projections of a double nut and to the projections being crushed and caught into a thread portion of the bolt when the double nut is fastened on the bolt. A plurality of projections (5, 5, 5) are formed on the peripheral-edge seat-surface of a thread hole (4) of the nut (2), and the nut (2) is fastened on a fastening nut (7), which has been fastened on a bolt (6) serving as a member (M) being fastened, with the projections (5) directed toward the fastening nut (7), so that the projections (5) deforming between the seat surfaces (3, 8) of the both nuts (2, 7) are caught into a threading portion between the thread hole (4) of the nut (2) and the thread (9) of the bolt (6) to enable prevention of loosening of the both nuts (2, 7).
摘要翻译：当双螺母紧固在螺栓上时，通过增加由于双螺母的突起的变形而产生的摩擦力以及突起被挤压并卡入螺栓的螺纹部分中，增加了锁定螺母的锁定效果。在螺母（2）的螺纹孔（4）的周缘座面上形成有多个凸起（5,5,5），螺母（2）紧固在紧固螺母（7）上，，所述凸起（5）在所述座面（3）之间变形，并且所述凸起（5）指向所述紧固螺母（7），所述凸起（5）已经紧固在用作被紧固的构件（M）的螺栓（6）（2,7）的螺纹孔（8,8）卡入螺母（2）的螺纹孔（4）与螺栓（6）的螺纹（9）之间的螺纹部分中，以防止螺母两个坚果（2，7）。

摘要： PROBLEM TO BE SOLVED: To perform rapid fastening work of a double nut, to easily confirm that an outside nut is doubly fastened, and besides to improve a locking effect through the increase of a friction force at the breakage spot of the coupling part thereof. SOLUTION: Two nuts 2a and 2b are paralleled and the seat surfaces 3 and 3 of the two nuts 2a and 2b are intercoupled through coupling tools 5, 5, and 5. The intercoupled two nuts 2a and 2b are fastened simultaneously with fastening of a bolt, the coupling tools 5, 5, and 5 are broken to further fasten one nut 2b, and unfastening of the nuts 2a and 2b is prevented from occurring.

摘要： PROBLEM TO BE SOLVED: To improve loosening-preventive function of a locknut by making fronts of projections formed on a seating surface of the nut bite into a screw part of a bolt at the time of fastening of the bolt and nut, rolling the crushed projections into the screw portion of the bolt, and thereby increasing friction. SOLUTION: Projections 5 each having a claw 6 directed to a center portion of a screw hole 4 of a nut 2 are formed on a seating surface 3 of the nut 2. The nut 2 is fastened in respect to a bolt 7 on the side of a fastened member M, from the side of the projections 5. The projections 5 biting into a screw part 10 of the bolt 7 and deformed are rolled into the screwing part between the screw hole 4 of the nut 2 and the screw part 10 of the bolt 7, for preventing loosening of the nut 2.
