The motor comprises a rotary shaft, and a ring engaged on one terminal end of the shaft and a casing comprising an end plate (4). The end plate houses a bearing (17) which internal cylindrical face (20) defines a seating in which the ring is received. The bearing includes a base (19) and a edge (18) opposite to the base. The bearing includes several discontinuous projections (22) adjacent to the edge of the bearing, and extending radially in the direction of an axis (12). The projections also extend in a common plane perpendicular to this axis (12), and are spaced apart. The projections provide an elastic grip, retaining the bearing in position, and may be made from a moulded plastic material. |
