ーバーロード検出機構。[Claims for Utility Model Registration] 1. A piston that has a drive magnet array and reciprocates within the cylinder by fluid pressure, and a driven magnet array that attracts the drive magnet array and moves into the cylinder in synchronization with the piston. In a magnetic coupling type rodless cylinder equipped with an external slider that reciprocates along the axis, the rodless cylinder is equipped with a pressure sensor for detecting an axial thrust at an intermediate position of the stroke of the external slider. Features an overload detection mechanism in the rodless cylinder. 2. A piston that has a drive magnet array and reciprocates inside the cylinder by fluid pressure; and an external mover that has a driven magnet array that mutually attracts the drive magnet array and reciprocates along the cylinder in synchronization with the piston. An overload detection mechanism in a rodless cylinder, characterized in that the rodless cylinder is equipped with a position sensor for detecting that the piston has stroked to a terminal position. . 3. A piston that has a driving magnet array and reciprocates inside the cylinder by fluid pressure; and an external mover that has a driven magnet array that mutually attracts the driving magnet array and reciprocates along the cylinder in synchronization with the piston. An overload detection mechanism in a rodless cylinder, characterized in that the rodless cylinder is equipped with a magnetic sensor for detecting a positional deviation of the magnetic coupling.
