リンダ。 A slider having a through hole is slidably fitted onto a tube made of a non-magnetic material into which a piston is airtightly and slidably fitted, and either the outer periphery of the piston or the inner periphery of the through hole is fitted. A cylinder member having a permanent magnet fixed to one side and a permanent magnet or magnetic material fixed to the other side so that the slider slides integrally with the piston by the magnetic attraction force acting between the two is attached to a pair of end covers. A plurality of pieces are passed parallel to each other between them, and at least one end thereof,
The end cover is provided with a split part, and the ends of the cylinder members are sandwiched between the split parts and fixed by tightening. One end and the other end of each cylinder member are communicated with each other through a passage provided in each end cover, and a fluid pressure supply/discharge port is opened in each passage, and each slider is connected to a connecting plate. A rodless cylinder characterized in that the rodless cylinders are integrally connected to each other while allowing movement in parallel directions.
