Claim Text:
1. A hand-held tool gear mechanism unit, comprising: a drive gearwheel having a first rotational axis; an output gearwheel having a second rotational axis spaced apart radially from the first rotational axis; a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio, the connecting unit coupling the drive gearwheel and the output gearwheel in such a way that the drive gearwheel and the output gearwheel are pivotable relative to one another about a pivot axis; a pivoting housing including (i) a first part fixed relative to the first rotational axis and defining a pivoting opening through which the second rotational axis extends and (ii) a second part extending around the second rotational axis, projecting through the pivoting opening, and configured to pivot about the pivot axis with the output gearwheel; and an output shaft configured at least partially integrally with the output gearwheel, the output shaft extending into the second part, wherein the second part includes an articulation closure configured to cover more than 90% of a region of the pivoting opening that is uncovered by the output shaft.
