チユエータ。[Claims for Utility Model Registration] Either a magnet or a coil disposed within the magnetic field of the magnet is connected to an output shaft to form a movable part, and by energizing the coil, electromagnetic force can be reduced. In the direct-acting actuator, the movable part is linearly moved by the action of: a protrusion provided at the center of the movable part, and a protrusion provided on the fixed part facing the movable part. a compression coil spring disposed between at least one of the protruding parts, the fixed part and the movable part, and a bowl-shaped washer interposed between the end of the compression coil spring and the protruding part. A direct-acting actuator comprising: the washer, and the protruding portion is in contact with the bottom of the inner surface of the washer.
