Description
Claims (1)
- 雄ねじ部を有しモータによって回転されるシャフトと、このシャフトの前記雄ねじ部に進退自在に螺合された雌ねじ部材と、この雌ねじ部材に固定されて前記シャフトの軸方向に移動する移動筒と、前記雌ねじ部材の外側に配置された支持筒と、この支持筒を支持するハウジングとを備えているリニアアクチュエータにおいて、
前記支持筒は樹脂が使用されて丸パイプ形状に形成されているとともに、前記雌ねじ部材を回り止めする回り止め部が内周に形成されており、
前記ハウジングは分割面が前記シャフトの軸線を含むように分割された第一分割体と第二分割体とが合わされて形成されており、
前記第一分割体と前記第二分割体との合わせ面間には、機械的強度の大きい材料が使用されて内径が前記支持筒の外径と等しい丸パイプ形状に形成された補強筒の一端部が、挟み込まれており、
前記支持筒の先端部外周には鍔部が突設されており、この鍔部の支持部側端面に前記補強筒の先端面が固定されている、
ことを特徴とするリニアアクチュエータ。
