Abstract: In a rodless cylinder unit with brake, which comprises a sliding table slidably held on a cylinder tube, brake bands inserted into the sliding table and both ends thereof fixed on both ends of the cylinder tube, and said sliding table provided with a brake for squeezing the brake bands, a slit with open upper end is formed on a side of the rodless cylinder of the cylinder tube, an air supply tube is accommodated in the slit, one end of the air supply tube is connected to the sliding table, and the other end of the air supply tube is connected to an end of the cylinder tube. When the air for brake release is supplied to the brake through the air supply tube, the brake is released, and the sliding table becomes movable. When the sliding table is moved, the air supply tube accommodated in the slit is overlapped or not overlapped with very low friction depending upon the moving direction of the sliding table.
