LOCKING FASTENER ASSEMBLING BODY

Japanese Patent JP3808812

B2

PROBLEM TO BE SOLVED: To provide an improved locking fastener assembling body.
SOLUTION: The locking fastener assembling body comprises a nut and washer. Each nut and washer have a load supporting face which opposes each other, and the supporting face has a series of slightly slanting faces which extend in a ring-shape and form a shallow wave. The load supporting face of the nut is an approximately spherical convex-shape, and the load supporting face of the washer is an approximately spherical concave-shape. A flat surface of the spherical concave-shape of the load supporting face of the nut is seated on a gorge-shaped surface of the spherical concave-shape corresponding to the load supporting face of the washer at a coplanar state. Further, a convex- shaped before-slanting supporting face of the nut is seated on a concave-shaped after-slanting supporting face of the washer, and the nut is prevented from moving back. A concave-shaped fastening face is formed on an outside end of the washer of the flange extending to a radial direction. The flange is bent when the assembling body is assembled, and the washer is elastically pushed to the nut.
