Abstract
PURPOSE: To make it possible to achieve a sure locking by forming a plurality of grooves on both end faces of the first nut and absorbing effectively the force applied to the first nut. CONSTITUTION: The first nut consists of the nut main body 2 and a conical protrusion 4. Three grooves 6 are formed at a positional interval at a central angle of 120 deg., respectively on the end face 5 of the nut main body 2. The extended line in the direction of extension of the grooves 6 pass the shaft center 7 and axial depth arrives at a half of the thickness of the protrusion 4. The protrusion 4 has a tapering shape and three grooves 17 at a positional interval at a central angle of 120 deg. are formed respectively at the leading end 14. The extended line of the grooves 17 in the direction of extension pass the shaft center 7 and the axial depth arrives at a half of the thickness of the nut main body 2. Grooves 6 and grooves 17 are arranged alternatively in such a way as to make a central angle of 60 deg. mutually. The second nut 20 opens with a smaller diameter than the largest diameter of the protrusion 4.
