The angular gear consists of a gear housing, a drive shaft provided with a helical gear, and a pinion. The drive shaft is provided with an operating means. The pinion, which meshes with the helical gear, is engaged with a rod suspending the venetian blind laths, by supporting ladder bands attached to the shaft. The drive shaft is provided with at least one bearing portion of circular cross section, which bearing portion cooperates with a complementary bearing portion in the gear housing. The bearing portion comprises a neck portion in the drive shaft, and in the housing there is at least one tongue having a hook-like means which, by the aid of the tongue, is biassed to protrude into the neck portion and which maintains the drive shaft in axial position in the gear housing.
