<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic brake device enabling a sufficient reduction in noise occurring during braking and sucking. <P>SOLUTION: This electromagnetic brake device comprises a fixed core around which an electromagnetic coil is wound, a movable core biased by a braking spring installed in the clearance thereof from the fixed core to generate a braking force and attracted by the fixed core to release the braking, and an elastic part installed so that it is partly projected from one end faces of the fixed core and the movable core facing each other and brought into contact with the other end faces thereof facing each other when the movable core is attracted to reduce the impact forces of the fixed core and the movable core. The elastic part comprises a first elastic body and a second elastic body with different projected amounts from one end faces of the fixed core and the movable core facing each other. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
