PROBLEM TO BE SOLVED: To provide a simple structure to control an error of an axial position of an inner seal band relative to a slit of a rodless cylinder. SOLUTION: A piston mount 23 moves while an inner and outer seal bands 30 and 31 close a slit 3 when a fluid is supplied/discharged from a supply/ discharge port 15 of an end cap 10. A widthwise error of the inner seal band 30 relative to the slit 3 is controlled since the right and left positions of the inner seal band 30 are restricted by both ends thereof and a thin plate sliding contact member 100 stuck to a side 20c of a band passage groove 20b. As the thin plate sliding contact member 100 uses a different member from an inner moving body, a high abrasion-resistant material is employed besides the forming material of the band passage groove 20b. Accordingly, occurrence of widthwise errors in manufacture of the groove 20b and the band 30 are dealt with by suitably selecting the thickness of the sliding contact member 100 mounted thereon.
