The first magnet has a first surface facing the first coil, and the second magnet has a second surface facing the second coil. Each of the first and second surfaces has thereon N- and S-pole portions arranged in the first direction. In a state where the movable member is located at a center of its movable range, center positions of the first and second coils have differences from boundary positions of the N- and S-pole portions of the first and second magnets.
