Abstract
A hand tool includes an apparatus housing (2), a drive shaft part (10) which is rotatable in the housing, and toolholder part (18) which is mounted pivotably in the housing, is operatively connected to the drive shaft part and has a securing portion (24) projecting from the housing for the purpose of receiving a file, for example. A shaft journal (30) is secured in the drive shaft part (10) and is eccentrically positioned (R) in relation to the center line (A) of the drive shaft part. The shaft journal (30) supports, on its section (48) outside the drive shaft part, a movement-transmitting member (50') with an outer limit surface (52'). This member is arranged in drive engagement with a recess (54) in the end portion of the toolholder part (18) located inside the apparatus housing (2). In the recess (54) the movement-transmitting member (50') can move transverse to the toolholder part (18), with the outside (52') rolling against adjoining contact surfaces (56, 58) which delimit the recess. The circular eccentric movement of the shaft journal (30) about the center axis (A) of the drive shaft part (10) imparts to the toolholder part (18), mounted pivotably in the housing (2), a sidew…
