3 is preferably formed as one piece with a plurality of spigots 4 the spigots 4 extend essentially perpendicular to a main plane of extension h of the bearing plate 3 the spigots 4 are formed on a rear side 5 of the bearing plate 3 fig1 shows the front side 6 of the bearing plate 3 furthermore fig1 also shows that a plurality of lugs 11 are formed on an outer circular periphery 7 of the bearing plate 3 preferably four of the lugs 11 are disposed along the periphery 7 of the bearing plate 3 these can for example each be disposed at an angle w of 90 u00b0 to each other about a middle axis m 1 the bearing plate 3 is produced from metal preferably steel in a step s2 a brush carrier part 12 see fig3 is provided the brush carrier part 12 has through openings 13 the through openings 13 can be formed in the region of indentations 14 in the brush carrier part 12 the brush carrier part 12 is preferably produced from synthetic material in a step s3 the brush carrier part 12 is pushed with its through openings 13 onto the spigots 4 of the bearing plate 3 subsequently the spigots 4 are shaped by means of wobble or radial riveting in such a way that a head 15 is formed as shown for spigot 4 u2032 see fig3 the head 15 engages behind the brush carrier part 12 and therefore fixedly connects the brush carrier part 12 to the bearing plate 3 during radial or wobble riveting.
