A manifold comprises a base material section made from an amorphous resin, a solenoid valve section including a plurality of solenoid valves made up of valve bodies, and a coupling section including a plurality of pipe couplings. The overall surface of the base material section is covered in a surrounding fashion without pinholes by a protective film, which is a dense layer film made from a chemically stable material. The manifold is surrounded by a protective box as necessary.

Manufacturing method for fluid passage forming member made of synthetic resin

A rodless cylinder comprises a cylinder tube and guide shafts which are arranged in parallel to one another. The cylinder tube comprises a piston therein which is displaceable in the axial direction. Driving magnets are provided on outer circumference of the piston. A slider, which is displaceable in the axial direction, is provided on the guide shafts. The slider is supported on the guide shafts by the aid of ball bushes. Driven magnets, which correspond to the driving magnets, are provided in a hole of the slider. Inner circumferential surfaces of the driven magnets are slightly separated from an outer circumferential surface of the cylinder tube. Accordingly, it is unnecessary to apply any surface treatment to the cylinder tube, and it is possible to avoid appearance of dust or the like. It is unnecessary to assemble the rodless cylinder with a high degree of accuracy, and thus the production cost can be reduced.
