OG exemplary drawing
 
1. An oscillating machine tool having a tool receiving device which is movable around an output shaft axis in an oscillating manner,
wherein said tool receiving device is adapted to hold a tool device in such a manner on the oscillating machine tool that the output shaft axis and an axis of rotation of the tool device are substantially coincident,
wherein said tool receiving device comprises at least one torque transmission region and a holding device,
wherein, for transmitting a driving force to the tool device, said torque transmission region has at least two output area regions facing towards the output shaft axis and which are spaced apart from the output shaft axis, each output area region having a plurality of surface points,
wherein tangent planes to the surface points are inclined relative to an axial plane which includes the output shaft axis,
wherein said tangent planes are inclined relative to a radial plane extending perpendicular to the output shaft axis, and
wherein the at least two output area regions define a recess suitable for receiving at least a portion of the tool device.
