Abstract

　ベッドの床上の荷重を検出するための種々の手段が提案されているが、荷重センサがベッドと別体に構成され、また外部に設置されているため種々の課題がある。 　本発明では、ねじシャフト１の一端側を基体２に回転可能に支持すると共に、ねじシャフトに雌ねじ部材３を螺合し、雌ねじ部材に固定した作動棒体４をねじシャフトの軸方向に進退可能に構成したアクチュエータにおいて、基体には、ねじシャフトと同軸に、スラスト軸受け６と、それを介してねじシャフトの一端側を軸方向に支持する作動筒体８を設けると共に、この作動筒体と、基体側の支持部材８との間に検出筒体９を設け、検出筒体の外面に歪みゲージ１０を取り付けた荷重センサ内蔵アクチュエータにより上記の課題を解決するものである。
