ABSTRACT:
According to the rodless power cylinder of the present invention, plug members are inserted in the bore of the cylinder barrel. A slit is provided on the cylinder barrel and extending in parallel to the axis of the cylinder barrel. A piston is disposed in the bore of the cylinder barrel and is movable along the slit. An external carriage which is connected with the piston by a yoke extending through the slit is provided. An inner seal band which closes the inner opening of the slit is disposed in the cylinder barrel along the slit. The ends of the inner seal band are clamped between the securing screws and the shank of the plug members, The securing screw extends through the slit from a fitting plate disposed on the outer wall of the cylinder barrel. The fitting plate is secured to the outer wall of the cylinder barrel by mounting bolts threaded into the plug members through the slit. Therefore, the inner seal band and the outer seal band can be secured without any machining of the cylinder barrel.
