Claims

[Claims for Utility Model Registration] (1) A nut body having a plurality of concave grooves parallel to the axial direction and shorter than the axial length of the nut and having a narrow opening width on the inner diameter side of the threaded portion of the nut; A bridge member that is fitted in the groove so as to be movable in the axial direction and has an inner diameter thread machined simultaneously with the inner diameter thread of the nut and has a length shorter than the depth dimension of the groove; and a bridge member that applies an axial force to the bridge member. A locking nut characterized by further comprising a bridge member pressing means attached to one end side of the nut body. (2) The loosening mechanism according to claim 1, wherein the bridge member pressing means comprises a pressing setscrew screwed onto one end of a nut and whose tip end surface abuts the end surface of the bridge member. Stop nut. (3) The bridge member pressing means includes a tension bolt rotatably fitted loosely into one end of the nut, and a female thread provided on the bridge member that engages with a male thread at the tip of the tension bolt. The locking nut according to claim (1), characterized in that it consists of:
