Abstract (en)
The invention refers to a plate-like backing pad member (9) for use with a hand-held and hand-guided power tool (1). The backing pad member (9) is adapted for releasable attachment to a driving shaft (27) of the power tool (1) by means of a mechanical form fit connection arrangement comprising a protrusion member (16) connected to the driving shaft (27) and a recess member (17) connected to the backing pad member (9). The form fit connection is releasable in an axial direction running parallel to a rotational axis (13) of the backing pad member (9). The protrusion member (16) is held in the axial direction within the recess member (17) by means of an axial holding arrangement. It is suggested that the axial holding arrangement comprises at least one permanent magnet (40) on the one hand and at least one ferromagnetic element (41) or at least one further permanent magnet on the other hand exerting a magnetic force for holding the protrusion member (16) in the axial direction within the recess member (17). The at least one permanent magnet (40) or the at least one ferromagnetic element (41) or the at least one further permanent magnet is located in or makes part of the recess member (17).
