係止させることを特徴とする。Means for solving the problem, ie, the method of the present invention, is to bend the circumferential edge of the boss portion protruding from the seat surface of the nut radially outward in advance so that the circumferential edge and the seat surface An annular groove is formed in between, and a screw shaft insertion hole of the washer is formed to be slightly larger than the outer diameter of the boss portion, and a plurality of locking protrusions are provided at appropriate intervals on the periphery of the washer. After the washer is fitted into the boss portion, the locking protrusion is pressed and bent by the seat surface to be locked in the annular groove.
実施例
以下、本発明の実施例を図面に基づいて説明する。第１
図において、ナツト１１の座面１３に環状のボス部１４
をねじ穴１２と同心状に突設する点は従来方法と同じで
あるが、該ボス部１４の周端縁１５を予め半径方向外方
へ屈曲して、該周端縁１５と座面１３との間に環状溝１
６を形成しである。この周端縁１５のかしめによる環状
溝１６の成形は、ボス部１４の成形加工と同時に簡単に
行なえ、コスト高につながることはない。Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
In the figure, an annular boss portion 14 is formed on the seat surface 13 of the nut 11.
This is the same as the conventional method in that the boss portion 14 is protruded concentrically with the screw hole 12, but the circumferential edge 15 of the boss portion 14 is bent radially outward in advance so that the circumferential edge 15 and the seat surface 13 An annular groove 1 between
6 is formed. Forming the annular groove 16 by caulking the peripheral edge 15 can be easily performed at the same time as forming the boss portion 14, and does not lead to increased costs.
一方、座金１７のねじ軸挿通穴１８はボス部１４の外径
寸法すなわち屈曲した周端縁１５の外径寸法よりやや大
きく形成し、その周縁に周方向に９０度ずつ間隔をおい
て４つの係止突起１９を設けである。この係止突起１９
の加工も座金１７のねじ軸挿通穴１８を打法き加工する
際、同時に加工できるからコスト高につながることはな
い。On the other hand, the screw shaft insertion hole 18 of the washer 17 is formed to be slightly larger than the outside diameter of the boss portion 14, that is, the outside diameter of the bent peripheral edge 15, and four holes are formed on the peripheral edge at intervals of 90 degrees in the circumferential direction. A locking protrusion 19 is provided. This locking protrusion 19
Since the machining can be performed at the same time when the screw shaft insertion hole 18 of the washer 17 is punched, the cost does not increase.
２０は座金１７の裏側に接着したシールワッシャで、ゴ
ムその伯の弾性材料でつくられ、そのねじ軸挿通穴２１

に設定されている。このようなシールワッシャ２０を接
着した座金１７は、シート状のシール材を接着した金属
板からプレスで打法いて安価に量産することができる。20 is a seal washer bonded to the back side of the washer 17, which is made of an elastic material such as rubber, and is inserted into the screw shaft insertion hole 21.
The inner diameter of is set to be slightly larger than the outer diameter of the male thread to be inserted. The washer 17 to which such a seal washer 20 is bonded can be mass-produced at low cost by pressing a metal plate to which a sheet-shaped sealing material is bonded.

ボス部１４に嵌合したのち、係止突起１９を座面１３で
押圧屈曲せしめて環状溝１６に係止させると、第３図の
ように、座金１７がナツト１１に対して回転自在に組込
まれる。Next, after fitting the washer 17 with the seal washer to the boss portion 14 of the nut 11, the locking protrusion 19 is pressed and bent by the seat surface 13 to lock it in the annular groove 16, as shown in FIG. , a washer 17 is rotatably assembled into the nut 11.
なお、以上の説明ではシールワッシャ２０を接着した座
金１７をナツト１１に組込んだが、本発明方法を、第４
図に示すように、座金１７だけを組込む場合にも適用で
きることは勿論である。In the above explanation, the washer 17 to which the seal washer 20 was bonded was assembled into the nut 11.
Of course, the present invention can also be applied to the case where only the washer 17 is assembled as shown in the figure.
