Abstract
A parking lock for a motor vehicle includes a pivotably mounted locking pawl (), an interlocking element (), and a guide rod (). A spring element () preloads the locking pawl () in a disengagement direction of the parking lock. A first free end () of the spring element () is supported directly on a support section () of the locking pawl () and, during the swiveling of the locking pawl (), rests against the support section () in a stationary manner. A second free end () of the spring element () is supported directly on a support contour () of the guide rod () and, during an axial movement of the guide rod (), slides along the support contour (). The geometry of the support contour () is configured such that the preload force of the spring element () does not decrease during the disengagement of the parking lock.
