Abstract
An actuator includes a fixed section that includes a spindle and a coil fixed to the spindle, a first movable section that includes a first magnet magnetized in an inside-outside direction and disposed to cover the outer peripheral surface of one end in an axial direction of the fixed section, that is mounted on the spindle in an elastically-maintained state, and that is movable in the axial direction, and a second movable section that includes a second magnet magnetized in the inside-outside direction and disposed to cover the outer peripheral surface of the other end in the axial direction of the fixed section, that is mounted on the spindle in an elastically-maintained state, and that is movable in the axial direction. When current flows in the coil, the first movable section and the second movable section move in the opposite directions.
