Title: ELECTROMAGNETIC BRAKE DEVICE
Abstract:
The present invention provides an electromagnetic brake provided with a damping rubber mounting structure having extended life obtained by configuring the damping rubber mounting structure such that, when compressed, protrusion from the upper surface-side outer periphery of damping rubber and riding-over are prevented. This electromagnetic brake is provided with a core having a damping rubber insertion section in which a recess is formed by the tip of a drill. The electromagnetic brake is characterized in that the damping rubber is provided within the damping rubber insertion section, and the damping rubber has, at the center thereof, a through-hole extending therethrough in the thickness direction thereof and having a greater diameter than the recess formed by the tip of the drill.
