Claims

[Claims for Utility Model Registration] A pair of end plates, a cylinder body between these end plates, a mover movable along the outer surface of the cylinder body, and a piston that reciprocates within the cylinder body. A rodless cylinder that supplies pressure fluid from a port opened in the end plate to a pair of pressure chambers partitioned by a piston to move the mover integrally with the piston in synchronization with the piston. Ports for individually supplying pressure fluid to the pair of pressure chambers are provided in the front and on the side facing away from each other, and these ports are connected to each pressure chamber by passages provided in the end plate and the cylinder body A centralized piping mechanism for rodless cylinders, which is characterized by having two cylinders communicate with each other.
