ンダ。 Between a pair of head covers, a plurality of cylinder tubes made of a non-magnetic material and having pistons fitted therein in an airtight manner and freely slidable are fixed in parallel to each other, and a plurality of cylinder tubes are fixed in parallel to each other. A slider formed with a through hole is fitted into the through hole so that it can relatively freely slide, and a permanent magnet is fixed to either the outer periphery of the piston or the inner periphery of the through hole. , a permanent magnet or a magnetic body is fixed to the other side, and the slider is caused to slide integrally with the piston by a magnetic attraction force between the permanent magnet and the permanent magnet or the magnetic body. Rotless cylinder.
