ABSTRACT:
The brush holder comprises a cage and a detachable clip. The cage serves to accommodate a brush and has a channel. The clip has a central leg positioned in the channel. A self-winding band spring for biassing a brush is fixed at its outer end to the central leg, which also includes engaging means, e.g. in the form of a tongue, for retaining the central leg in the channel. The clip has also two side legs bearing elastically on to the outer sides of the cage to prevent rocking of the clip relative to the cage. The central leg has preferably raised side edges and the cage is preferably cut out from a hollow cross shaped section.
