Claims (1)
- 下記のA乃至Fの構成を有する螺子におけるドライバービット嵌合用十字溝の構造。
A:螺軸部の一端にヘッド部を有し、該ヘッド部の頭頂面にドライバービット嵌合用十字溝が形成されている。
B:上記十字溝の第一乃至第四ウイング溝の各左右内側面は一対の基端部内側面と一対の中間部内側面と一対の先端部内側面とに区画されている。
C:上記基端部内側面は隣接するウイング溝の上記基端部内側面に対し外側方へ屈曲し、上記中間部内側面は上記基端部内側面に対し外側方へ屈曲し、上記先端部内側面は上記中間部内側面に対し外側方へ屈曲している。
D:上記各屈曲角は基端部内側面の屈曲角<中間部内側面の屈曲角<先端部内側面の屈曲角の関係に設定されている。
E:上記基端部内側面の対面によって十字溝の中央穴へ向け漸次拡大する台形の基端部溝を画成し、上記先端部内側面の対面によって先方へ向け漸次拡大する逆台形の先端部溝を画成し、上記中間部内側面の対面によって上記基端部溝と先端部溝間に略平行な中間部溝を画成している。
F:上記基端部内側面と中間部内側面と先端部内側面とは何れも十字溝の開口面へ向け拡開する仰角を有している。
