Abstract
At the time of assembling an electric motor, plain bearings are installed over a worm shaft to form a shaft assembly. Then, the worm shaft together with the plain bearings is inserted into a gear housing in an inserting direction, which is generally parallel to an axial direction of the worm shaft, such that each of the plain bearings is press fitted into a corresponding installation part of the housing.
