Claims (4)
- ハウジングと、このハウジングに軸中心回りに回転自在かつ軸方向に移動不能に支持されたねじ軸と、このねじ軸に螺合したナットを含み前記ねじ軸の回転によりねじ軸の軸方向に移動させられる直動体とを備えた直動案内装置であって、
前記ハウジングに前記ねじ軸の軸方向に沿う複数の案内面を設け、これら複数の案内面は2面ずつが対となり、これら対となる2つの案内面は、互いに非平行で背を向き合い、前記直動体に、軸方向に分割され互いに連結される複数の分割体を設け、この分割体に、前記各案内面に接する複数の被案内体を支持し、前記複数の分割体を、案内面と被案内体との間に予圧を付与するように連結したことを特徴とする直動案内装置。 - 前記分割体に、ねじ軸の径方向に突出するトラニオン軸を設け、このトラニオン軸に、前記被案内体を構成する案内ローラを設けたことを特徴とする請求項1記載の直動案内装置。
- 前記ハウジング内の内圧を外圧よりも高く設定したことを特徴とする請求項1または2に記載の直動案内装置。
- 前記直動体の往復動によってハウジング内に生じる圧縮側と膨張側の内圧差を緩和するベントフィルターをハウジングに設置したことを特徴とする請求項1〜3のいずれかに記載の直動案内装置。
