Abstract
An electric power tool includes an electric motor, an output shaft, a housing that houses the electric motor and at least part of the output shaft, and a reduction gear drivingly arranged between the electric motor and the output shaft. The reduction gear includes a load sensitive part that is rotatable in response to reaction forces created during operation of the power tool. A torsion spring, arranged to counteract any such rotation, includes a first end and a second end, the first end including a first connective interface that is rotationally lockable to a connective interface of the load sensitive part, and the second end including a second connective interface that is rotationally lockable with respect to at least one of the housing and the motor. At least one of the first and the second connective interfaces includes an element for prohibiting axial movement between the connected parts.
