Claims

[Claims for Utility Model Registration] 1. A bearing that supports a rotating shaft, a bracket that houses the bearing, a yoke of an electromagnetic brake fixed to the bracket, and a guide that protrudes in the axial direction from the end surface of the yoke. A movable disk arranged to slide along the pin, an end plate fixed to the tip of the guide pin, and a rotating shaft sandwiched between the movable disk and the end plate so as to be movable only in the axial direction. A brake motor comprising: a brake disc fitted into a brake disc; and a grease receiving collar fixed to the rotating shaft at a position adjacent to the bearing and facing an inner surface of the yoke,
A brake motor characterized in that a first annular protrusion having a hook-shaped cross section is provided on an inner surface of the yoke facing the rotating shaft, and a grease reservoir is formed in a portion facing the grease receiving collar. 2. The brake motor according to claim 1, further comprising a second annular protrusion projecting in the axial direction on a surface of the grease receiving collar facing the grease reservoir.
