Abstract

The rotary impact mechanism has a plurality of helical springs disposed adjacent to the outer peripheral surface of a rotary inertia member which springs are anchored at one end to the inertia member and at the opposite end to a rotary driving input member so that upon relative rotative movement between the input and inertia members the springs are loaded and thereafter function to rotatively drive the inertia member. The inertia member carries at least one pawl which is capable of engagement and disengagement from a driven, toothed, output member, the pawl impacting against a tooth of the output member to drive the latter when the inertia member is rotatively driven by the springs.
