α スリット
Claims (2)
- 外部からの荷重を受けて変形するハウジング(26)の内部に収納した環状の磁歪材料(27)にコイル(29)を巻き付け、ハウジング(26)の変形に伴って変形する磁歪材料(27)の透磁率の変化をコイル(29)のインダクタンスの変化として取り出すことにより、前記荷重の大きさを検出する荷重センサにおいて、
前記ハウジング(26)はスリット(α)を有するC字状断面を有しており、前記荷重の入力によりスリット(α)の幅が減少する方向に変形するとともに、限界値以上の荷重が入力したときにスリット(α)が閉じることでハウジング(26)の最大変形量を規制することを特徴とする荷重センサ。 - 前記ハウジング(26)は荷重受け部(26f)を有しており、この荷重受け部(26f)は荷重伝達部材(13)に対して線接触あるいは点接触することを特徴とする、請求項1に記載の荷重センサ。
