ABSTRACT:
A propeller shaft provided including, a tubular body (1) and a balance weight (5) attached to the body (1). The propeller shaft is characterised in that a stud (4) is welded to a cylindrical outer surface of the body (1) so as to project outwardly from that surface. The weight (5) has a hole (8) therethrough and located over the stud (4) so that the stud (4) extends into the hole (8). A terminal end portion (10) of the stud (4) contacts the weight (5) so as to thereby prevent separation of the weight (5) from the stud (4). A method for attaching a balance weight to a propeller shaft is also provided.
