This invention is an actuator having the function of control operation displacement. The invention comprises of cylinder ( 100 ), pistons ( 160 ), a rotating axis ( 140 ) rotatably mounted through the wall of the cylinder ( 100 ), a power transmission unit ( 120, 130 ) connected between the piston ( 160 ) and the rotating axis ( 140 ), the flow pathways ( 11, 12 ) connecting the first and the second space ( 101, 102 ) to the exterior solenoid valve ( 20 ), a magnet ( 231 ) provided on one side of the piston ( 160 ), a guide ( 211 ) provided on one side of the cylinder ( 100 ), a slider ( 213 ) being guided by the guide ( 211 ) and moving reciprocally along the piston ( 160 ), a magnet sensor ( 235 ) adjacent to the wall of the cylinder.
