Abstract

An electric hand tool is disclosed which has a gt (15), received in a housing (10), with a gear shaft (20) and also has at least one radial bearing (30) for rotary support of the gear shaft (20), the inner bearing ring (301) of the radial bearing being fixed on the gear shaft (20) and the outer bearing ring (302) of the radial bearing being fixed in a bearing box (31) disposed in the housing (10), in each case being fixed axially nondisplaceably. For simple assembly of the gt (15) without tools, the outer bearing ring (302) of the radial bearing (30) rests with a sliding seat in the bearing box (31) and is fixed by means of a clamping bracket (32) fixed to the bearing box (31).
