The spring washer fixing bolt 5 is a member in which the bolt and the spring washer are fixed and integrated. The spring washer fixing bolt 5 has the same effect as the effect obtained when the spring 1 is engaged with the bolt 1.

図１７は、ナットにスプリングワッシャを固着したスプリングワッシャ固着ナット６の側面図である。スプリングワッシャ固着ナット６は、ナットとスプリングワッシャを固着し一体化した部材である。スプリングワッシャ固着ナット６は、ナット３にスプリングワッシャ２を係合した場合に得られる効果と同等の効果を有する。  FIG. 17 is a side view of the spring washer fixing nut 6 in which the spring washer is fixed to the nut. The spring washer fixing nut 6 is a member in which the nut and the spring washer are fixed and integrated. The spring washer fixing nut 6 has the same effect as the effect obtained when the spring 3 is engaged with the nut 3.

図１８は、係合したスプリングワッシャ２とナット３以外に、別のナットをボルト１の頭部に近いねじ軸１２に螺合した斜視図である。スプリングワッシャ２と係合したナット３の締め付けのみでは、緩みに対する不安が払拭できない場合、ボルト１と通常のナットで被締結部材Ａ８１と被締結部材Ｂ８２を螺合した後に、スプリングワッシャ２と係合したナット３により締め付ける。  FIG. 18 is a perspective view in which another nut other than the engaged spring washer 2 and the nut 3 is screwed to the screw shaft 12 near the head of the bolt 1. If the uneasiness of loosening cannot be wiped out only by tightening the nut 3 engaged with the spring washer 2, the member A 81 and the member B 82 are screwed together with the bolt 1 and a normal nut and then engaged with the spring washer 2. And tighten it with the nut 3.
