Abstract

1. Screwing tool with reversible ratchet having clamping bodies (20, 58) in wedge-shaped clamping spaces between an outer driving ring part (7, 34) and an inner driven core part (9, 36) which clamping bodies can be displaced by a rotatable switching member into the released position with respect to the wedge walls of the associated clamping space by means of drive members (23, 48) engaging on the clamping bodies, characterized in that the displacement direction of the drive members (23, 48) lies transverse to the plane of rotation of the driving ring part (7, 34).
