Abstract
A hand-held power tool drive device includes at least one wobble drive unit that has at least one rotatably mounted drive element, with at least one wobble unit positioned on the at least one drive element. The drive device also includes at least one counterweight unit that has at least one movably mounted compensating element configured to be driven by the at least one wobble unit. The at least one wobble unit includes at least one force application point that is configured to drive the at least one compensating element. An axis extending through a rotational axis of the at least one drive element and the at least one force application point encloses an angle of between 0° and 135° with a wobble element longitudinal axis of a wobble element of the at least one wobble unit.
