The shaft rod ( 2 ) according to the invention has, at one of its narrow sides, at least one recess ( 21 ) which is later provided in the shaft rod and in which a reinforcing element ( 24 ) is glued. The material externally of the shaft rod forms securing zones ( 32, 33 ) which serve for the attachment of additional elements. The recesses are preferably applied in such a manner that hollow spaces free from Eloxal coating are exposed which may be utilized as recesses into which reinforcing elements are glued.
