Abstract:
The invention relates to an electric hand tool device, comprising an electric motor having an armature (12) having a commutator (10), and comprising a brush holder (2) for accommodating and guiding a brush (4) to the commutator in the radial direction (8), wherein the brush holder (2) comprises a spring means (6), which preloads the brush (4) in the radial direction (8); in order to reduce the rattling of the brush, the spring means (6) and the brush (4) interact in such a way that the brush (4) is loaded not only inwardly in the radial direction (8) but also in the tangential direction (16) and in the axial direction (14) and thereby is pressed against one wall (30, 32) each of the brush (2) in the tangential direction (16) and in the axial direction (14) and the position of the brush is thereby defined.
