Abstract (en)
[origin: EP2441724A1] A first displacing body includes: a first movable core; a driven body that is disposed so as to be separated from the first movable core; and a first lining that is disposed on a surface of the driven body near the first movable core. A rotating body is interposed between the first movable core and the first lining. A second displacing body includes: a second movable core that is disposed between the first movable core and the rotating body; and a second lining that is disposed on a surface of the second movable core near the rotating body. The first displacing body is forced by a first forcing body in a direction in which the first lining contacts the rotating body, and the second displacing body is forced by a second forcing body in a direction in which the second lining contacts the rotating body. A common electromagnet is disposed between the first and second movable cores. The electromagnet displaces the first and second movable cores in directions in which the first and second linings separate from the rotating body in opposition to the forces from the first and second forcing bodies.
