An elevator hoisting machine braking apparatus comprising: a rotating body that is rotated together with a rotating shaft; a first displacing body comprising: 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, the rotating body being interposed between the first movable core and the first lining, and the first displacing body being displaceable in a direction in which the first lining contacts with and separates from the rotating body; a second displacing body comprising: 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 second displacing body being displaceable in a direction in which the second lining contacts with and separates from the rotating body; a first forcing body that forces the first displacing body in the direction in which the first lining contacts the rotating body; a second forcing body that forces the second displacing body in the direction in which the second lining contacts the rotating body; and a common electromagnet that is disposed between the first and second movable cores (22,26), and that displaces the first and second movable cores (22,26) in the directions in which the first and second linings (25,27) separate from the rotating body in opposition to the forces from the first and second forcing bodies (19,20). a rotating body that is rotated together with a rotating shaft; a first displacing body comprising: 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, the rotating body being interposed between the first movable core and the first lining, and the first displacing body being displaceable in a direction in which the first lining contacts with and separates from the rotating body; 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 second displacing body comprising: 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 second displacing body being displaceable in a direction in which the second lining contacts with and separates from the rotating body; 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, a first forcing body that forces the first displacing body in the direction in which the first lining contacts the rotating body; a second forcing body that forces the second displacing body in the direction in which the second lining contacts the rotating body; and a common electromagnet that is disposed between the first and second movable cores (22,26), and that displaces the first and second movable cores (22,26) in the directions in which the first and second linings (25,27) separate from the rotating body in opposition to the forces from the first and second forcing bodies (19,20).
