According to the rodless power cylinder of the present invention, plug members (33) are inserted in the bore (34) of the cylinder barre (31). A slit (32) is provided on the cylinder barrel (31) and extending in parallel to the axis of the cylinder barrel. A piston (40) is disposed in the bore (34) of the cylinder barrel (31) and is movable along the slit (32). An external carriage (44) which is connected with the piston (40) by a yoke (42) extending through the slit (32) is provided. An inner seal band (50) which closes the inner opening of the slit (32) is disposed in the cylinder barrel (31) along the slit (32). The ends of the inner seal band (50) are clamped between the securing screws and the flank of the plug members (33). The securing screw (55) extends through the slit (32) from a fitting plate (53) disposed on the outer wall of the cylinder barrel (31). The fitting plate (53) is secured to the outer wall of the cylinder barrel (31) by mounting bolts threaded into the plug members through the slit (32). Therefore, the inner seal band and the outer seal band can be secured without any machining of the cylinder barrel (31). <IMAGE> |
