When there is no manufacturing error in each part, no shim adjustment is required. Because the box body, the worm shaft and the like adopt an economic processing mode, the manufacturing errors are inevitable. These errors add up and need to be eliminated by adjusting the axial position of the enveloping worm. The shim is typically adjusted. The gasket is arranged between the step surface of the worm bearing stopper on the ring surface and the inner ring of the bearing or between the outer ring of the bearing and the step surface of the bearing hole of the box body.
