Claims (5)
- 予め成形された雌ねじに対してねじ込まれる緩み止めねじにおいて、
ねじ山のフランク面が、雌ねじよりも緩傾斜な頂側フランク面と、この頂側フランク面とねじ山の谷底とに連なって雌ねじよりも急傾斜な谷側フランク面とから成り、これら頂側フランク面と谷側フランク面との交点付近が雌ねじに干渉する一方、当該干渉状態では谷側フランク面と雌ねじとの間に隙間が設定されることを特徴とする緩み止めねじ。 - 前記頂側フランク面と谷側フランク面との交叉角が、鈍角に設定されていることを特徴とする請求項1に記載の緩み止めねじ。
- 前記頂側フランク面と谷側フランク面との交叉部が、円弧面に成形されていることを特徴とする請求項1又は2に記載の緩み止めねじ。
- 前記ねじ山の頂部が平坦面に成形され、この平坦面と頂側フランク面との交点に対して前記雌ねじのフランク面が接するように構成されていることを特徴とする請求項1、2又は3に記載の緩み止めねじ。
- 前記谷側フランク面と雌ねじのフランク面との交点を、ねじ山高さの中間位置よりも高い位置に設定することによって、前記隙間が成形されていることを特徴とする請求項1、2、3又は4に記載の緩み止めねじ。
