Claims

[Claims for Utility Model Registration] (1) In a lock nut formed by screwing a plurality of nuts onto a bolt and polymerizing both nuts, one nut 11, 42 has a nut on the opposing surface 13, 51 of the other nut. A circumferential strip 14, 52 is formed which is concentric with the axis of the circumferential strip 14, 52, and two pressing surfaces 25, 25 are in contact with two places on either the outer circumferential surface 15 or the inner circumferential surface 53 of the circumferential strip 14, 52. ,35,35
, 47, 47, the convex portions 22, 32, 44,
By forming it on the facing surfaces 21, 31, 43 of the other nuts 12, 30, 41 with respect to one nut, when both nuts are superposed, the pressing between the peripheral surfaces 15, 53 of the circumferential strip and the convex portion Surface 25, 3
5 and 47 are configured to press against each other in a direction perpendicular to the axis. (2) The above-mentioned convex parts 22, 32 are the above-mentioned circumferential strips 14
Two pressing surfaces 25 in contact with two places on the outer peripheral surface 15 of
, 25, 35, 35, and the radius a of the outer peripheral surface at the tip of the circumferential strip 14 is smaller than the lengths b, b' between the tips of both pressing surfaces and the axis of the nut. A lock nut as described in claim 1 of the utility model registration claim characterized by: (3) Two pressing surfaces 47, 47 where the above-mentioned convex portion 44 touches two places on the inner circumferential surface 53 of the above-mentioned circumferential strip 52.
and the radius e of the inner circumferential surface at the tip of the circumferential strip
The lock nut according to claim 1, wherein d is greater than the length d between the tips of both pressing surfaces and the axis of the nut.
