Abstract

A lever (3) for the temporary disengagement of a parking lock (2) of a vehicle drive unit (1). The lever (3) comprises a fixing piece (31) for fitting the lever (3) onto a parking lock shaft (26), which extends inside the vehicle drive unit (1) and serves to actuate the parking lock (2). The lever (3) is a hand lever with a gripping handle (32). The gripping handle (32) is designed to enable a user to apply a manual force for manual actuation of the lever (3). When the lever (3) is fitted on the parking lock shaft (26) and moved, the parking lock shaft (26) is moved from an engagement position to a disengagement position. In the disengagement position, by further movement of the gripping handle (32) into a locking position, the lever (3) is blocked against a reverse movement out of the disengagement position.
