【発明の属する技術分野】この発明は、ナットの下端に
回転可能に座金を取り付けた座金付きナットに関するも
のである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nut with a washer having a lower end of a nut rotatably attached to a washer.
【０００２】[0002]
【従来の技術】周知のように、従来の座金付きナットに
おいては、座金は実質上平坦な形状のものが用いられて
いる。2. Description of the Related Art As is well known, in a conventional nut with a washer, a washer having a substantially flat shape is used.
【０００３】[0003]
【発明が解決しようとする課題】このような平坦な座金
によれば、当初の締付けは堅固に行うことができるが、
ばね力（ばね弾性力）が小さいため、例えば建築部材の
軽量気泡コンクリート（ＡＬＣ）パネルなどのように、
圧縮強度が余り高くない部材の締結に用いる場合には、
締結後に繰り返し作用する外力（特に微振動）によって
部材の表面に摩耗窪みが生じると、ナットとボルトの両
ねじ部の接触圧力、すわわち締付け力が減退して、緩み
が生じるという問題がある。According to such a flat washer, initial tightening can be performed firmly.
Since the spring force (spring elasticity) is small, for example, as in a lightweight cellular concrete (ALC) panel of a building member,
When it is used to fasten members whose compressive strength is not too high,
If the surface of the member wears due to an external force (especially microvibration) repeatedly acting after the fastening, there is a problem that the contact pressure of the two screw portions of the nut and the bolt, that is, the tightening force is reduced and loosening occurs. .
【０００４】この発明は、上記のような問題に鑑み、長
期にわたって締付け力を維持することができる座金付き
ナットを提供することを課題としている。[0004] In view of the above problems, an object of the present invention is to provide a nut with a washer capable of maintaining a tightening force for a long period of time.
【０００５】[0005]
【課題を解決するための手段】この発明は、座金の下端
に回転可能に座金を取り付けてなる座金付きナットにお
いて、座金を深皿形に形成するとともに座金に軸周りに
間隔をおいて上下にのびる複数のスリットを設けること
を特徴としている。SUMMARY OF THE INVENTION The present invention relates to a nut with a washer having a washer attached rotatably to a lower end of a washer, the washer is formed in a deep dish shape, and the washer is vertically arranged at intervals around an axis. It is characterized by providing a plurality of extending slits.
【０００６】この発明に係る座金付きナットにおいて
は、座金の深皿形状とスリット付きの構成上、座金のば
ね弾性力が大きく、長期にわたって所望の締付け力が保
持される。In the nut with washer according to the present invention, the spring elastic force of the washer is large due to the configuration of the washer having the deep dish shape and the slit, and the desired tightening force is maintained for a long period of time.
【０００７】[0007]
【発明の実施の形態】以下図面に基づいて、この発明の
座金付きナットの実施形態を説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a nut with a washer of the present invention will be described below with reference to the drawings.
【０００８】例示した実施形態は、ナット１１の下端に
形成した環状フランジ１２区画の環状溝１３に、上端に
環状フランジ１７を有するとともに軸周りに１２０°の
間隔をおいて上下にのびる三角の溝状のスリット１８を
形成した深皿形の座金１６の環状フランジ１７を、回転
可能に嵌合した構造からなっている。In the illustrated embodiment, a triangular groove having an annular flange 17 at the upper end and extending vertically at an interval of 120 ° around the axis is formed in the annular groove 13 of the annular flange 12 formed at the lower end of the nut 11. It has a structure in which an annular flange 17 of a deep dish-shaped washer 16 in which a slit 18 is formed is rotatably fitted.
【０００９】この実施形態においては、座金１６の深皿
形状とスリット１８により分割された各座金片による大
きなばね弾性力によって、堅固な締付け状態が維持され
る。In this embodiment, a firm tightening state is maintained by the deep spring shape of the washer 16 and the large spring elastic force of each washer piece divided by the slit 18.
【００１０】この発明は、このほか、スリットを方形の
