An actuator is equipped with a moveable part 160 that moves according to changes in an intake amount of air, a cylinder 140 that contains air and pumps the air through a fluid pipe 150 to the moveable part 160 according to pressure applied to the air, and a piston 130 that applies pressure to the air in the cylinder 140. Further, the actuator is equipped with a motor 100 that generates rotational force, and a screw 110 and a slide nut 120 that convert the rotational force to a force to move the piston 130. The air is enclosed in the moveable part 160, the cylinder 140 and the fluid pipe 150. |
