Claims

[Scope of utility model registration request]

A piston packing, which has a molded part on a part of its outer periphery that corresponds to the inner surface shape of an inner seal band that closes a slit formed along the axial direction in the cylinder barrel wall from the inside, is fitted into the fitting groove of the piston. In the slit tube type rodless cylinder, one of the seal mounting groove and the piston seal is provided with a locking recess, and the other side is provided with the locking recess with the molded part of the piston seal corresponding to the inner seal band. A rodless cylinder comprising a locking protrusion that engages with a recess and positions a piston seal in the circumferential direction.
