装置。 A bearing that supports a rotating shaft, a bracket that accommodates the bearing, a yoke of an electromagnetic brake fixed to the bracket, and a guide pin that is arranged to protrude in the axial direction from an end surface of the yoke so that it slides. The arranged movable disk, the end plate fixed to the tip of the guide pin, and the inner driver sandwiched between the movable disk and the end plate and fixed to the rotating shaft are fitted so as to be movable in the axial direction. In the brake motor, a first annular protrusion extending in the axial direction is provided on an end face of the housing of the bearing opposite to the end face of the inner driver, and a recess is provided in the end face of the inner driver in the axial direction. What is claimed is: 1. A bearing dust-proof device for a brake motor, characterized in that the annular groove is provided with a second annular protrusion extending along the outer peripheral surface of the first annular protrusion on an inner surface of the annular groove.
