The shaft (3) is provided with at least one bearing portion of circular cross section and this bearing portion cooperates with a complementary bearing portion in the gear housing (2). In connection to the bearing portion or portions there is a neck portion (14) in the shaft, and in the housing (2) there is at least one tongue (6) having a hook-like means which by the aid of the tongue is biassed to protrude into the neck portion and gear which maintains the shaft (3) in axial position in the gear housing (2).
