<p>[PROBLEMS] To obtain a rodless cylinder device of simple structure in which sealing performance can be assured easily over a long term and friction resistance is eliminated so that it can operate at low pressure. To obtain a rodless cylinder device in which the stroke of an external moving body can be increased as compared with the overall length of the cylinder body. [MEANS FOR SOLVING PROBLEMS] The rodless cylinder device has a piston body integrated with the central top portion of a rolling diaphragm, a cylinder body to which the piston body is fitted movably while the annular fixing portion on the fringe of the rolling diaphragm is secured, a slit extending in the axial direction after penetrating an inside/outside coupling body formed in the cylinder body, an inside/outside coupling body secured to the piston body and projecting to the outside while penetrating the slit, an outer moving body located on the outside of the cylinder body and secured to the inside/outside coupling body, and a mechanism for supplying/discharging pressure fluid into/from a pressure chamber formed between the rolling diaphragm, the cylinder body and the piston body.</p> |
