Abstract

PURPOSE: To make it possible to achieve a sure locking by forming a plurality of grooves respectively on both end faces of a nut and absorbing effectively the force applied to the nut. CONSTITUTION: A nut consists of the nut main body 2 and a protrusion 4 in a tapering shape. Three grooves 6 are formed with a positional interval at a center angle of 120 deg., respectively, on the end face 5 of the nut main body 2. Likewise, three grooves 17 are formed with a similar positional interval at the leading end 14 of the protrusion 4. The grooves 6 and grooves 17 are arranged alternatively so that they form the central angle of 60 deg. with their pairs. The extended line of the grooves 6 and grooves 17 in the extension direction passes the shaft center 7 and the axial depth arrives at a half of the protrusion 4 and the nut main body 2 in thickness. One end face of a washer 20 opens with a smaller diameter than the largest diameter of the protrusion 4, the other end face opens with a smaller diameter than the smallest diameter of the protrusion 4 and concentric fitting with the protrusion 4 is performed.
