Abstract

A device for shifting an operation element of an automatic transmission of a vehicle in a parking position includes a rotationally mounted locking comb directly coupled with the operation element, with a stop member, a locking pin which is designed in a first position to fix the locking comb and in a second position to release the locking comb for a rotational movement, and a rotationally mounted set collar with a switching cam and a catch, wherein the switching cam is formed at a rotational movement of the set collar to move the locking pin from the first position to the second position, and the catch is formed at the rotational movement of the set collar to entrain the stop member to turn the locking comb so far that the operation element is shifted to the parking position.
