るトラニオン部又はコラムのボスを該作動機の作
動方向に摺動できるように支持し、更にその摺動
を抑制するように摺動方向両側から夫々スプリン
グにより前記ボスに予圧を掛けると共に、この予
圧に抗して該ボスが一定距離摺動した時にリミツ
トスイツチが作動するようにしたことを特徴とす
る直線作動機の過負荷検出装置。 In a linear actuator, the trunnion part or column boss that fixes these to the base is supported so that it can slide in the operating direction of the actuator, and furthermore, the trunnion part or column boss that fixes these to the base is supported by springs from both sides in the sliding direction to suppress the sliding. An overload detection device for a linear actuator, characterized in that a preload is applied to the boss, and a limit switch is activated when the boss slides a certain distance against the preload.
