Abstract
A rodless cylinder is coupled to an elongated base. The construction for coupling the rodless cylinder to the base includes a hollow duct formed in the bottom wall of the base and extending along the entire length of the base. A projection extending along the entire length of the duct is formed on the upper inner wall of the duct when the base and duct are formed by a drawing or extrusion process. After the base is formed, the longitudinal ends of the projection are cut off by a predetermined length from both longitudinal ends of the base. The portions of the duct from which the projections are cut off act as receiving portions into which mounting nuts are inserted, and the end faces of the remaining projection act as stoppers which abut the inserted mounting nuts to position them. The upper walls of the duct above the receiving portions are cut off to form slits opening to the upper face of the base. The slits act as mounting bolt passages of the rodless cylinder. The rodless cylinder is coupled to the base by inserting mounting bolts through bolt holes on end caps disposed on both ends of the cylinder. The bolts further pass through the slits and engage the mounting nuts placed i…
