A rodless cylinder with a position detector and a brake has a sliding table which is slidably retained on a cylinder tube. A moving member (piston yoke) of the rodless cylinder is secured to the sliding table. A brake unit part is connected to one side of the sliding table, and a sensor part is connected to the other side of the sliding table. A brake plate is disposed to extend through the brake unit part. Both ends of the brake plate are connected to a first and second head covers, respectively, which are provided at both ends of the cylinder tube. A first and second brake shoes are disposed to sandwich the brake plate therebetween. The first brake shoe is subjected to brake spring force. A passage for supplying a pressure fluid is communicated with the other side of the sliding table. Thus, the brake is actuated by allowing the brake spring force, together with a fluid pressure if necessary, to act on the first brake shoe, and the brake is released by the action of a fluid pressure.
