Abstract
In a rodless cylinder 1, a band accommodating depression 60 having a transverse inner surface 62 extending along the width of a slit 12 of an inner hole 10 of a tube 2 and a wall surface 64 inclined with respect to the transverse inner surface 62 is formed on each side of the inner opening of the slit 12. In the case where one of the edges of the inner seal band 42 comes into contact with one of the wall surfaces 64, the other edge of the inner seal band 42 comes into contact with the other one of the transverse inner surfaces 62, while at the same time securing a distance I between the inner seal band 42 and an inner opening 58 of the slit 12. Once a fluid is introduced into the tube 2, the inner seal band 42 can be bent toward the slit 12 due to the distance I even in the case where one of the edges of the inner seal band 42 comes into contact with the transverse inner surface 62 and the other edge comes into contact with the wall surface 64. As a result, a rodless cylinder is provided in which by forming transverse walls and preventing the seal band from being displaced by more than a predetermined amount, the slit is accurately sealed and the moving unit can be positively moved.
