Abstract

　締結用ナットとロックナットとの締め付け合う力を向上させることができるロックナットを提供する。ボルト６に締め付けられた締結用ナット７の緩みを防止するためのロックナット１は、内部にねじ孔４が形成されかつ一方の座面３のねじ孔４の周縁に溝３０が形成されたナット本体２と、ナット本体２の溝３０に形成されかつナット本体２と同じ材質の複数の突起５とを備える。突起５は、ナット本体２の座面３と溝３０との境界線からナット本体２の中心方向に向けられたねじ孔４と反対側の外側面と、ナット本体２のねじ孔４の内面の延長となるようにされたねじ孔４側の内側面３２とを有する。溝３０の深さは、ロックナット１をボルト６に締め付けた際に複数の突起５が潰されても締結用ナット７のナット本体２側の座面８とナット本体２の座面３との間に入り込まない深さに設定されている。
