An electromagnetic valve, a circuit board on which a control circuit for controlling the electromagnetic valve is mounted, and a cover for covering the electromagnetic valve and the circuit board are installed on a device-attaching surface of an adapter plate disposed at one end in a direction of an axial line of an air cylinder, in a manner so as to be housed within a surface area of the device-attaching surface, and an output port of the electromagnetic valve and a pressure chamber of the air cylinder are allowed to communicate with each other through an air through-hole provided in the adapter plate.
