Abstract

The invention relates to a parking lock (1) for the transmission of a motor vehicle, comprising a parking lock wheel (2). The parking lock comprises a pawl (3) which is designed to interact with the toothing of the parking lock wheel (2) in order to block the rotation of the parking lock wheel (2) in a locked position and to release the rotation of the parking lock wheel (2) in an unlocked position. The pawl (3) can be actuated via a slide (9) and is received on a pin (5) in a pivotal manner about a rotational axis (4), and a guide rod (7) and a spring element (8) are arranged on the slide (9). The slide (9) is operatively connected to the pawl (3) and can be moved axially in the longitudinal direction of the guide rod (7) in order to actuate the pawl (3). A guide element (6) is designed to guide the guide rod (7) and receive the spring element (8), and the guide element (6) has a casing (10) with a base (11), wherein the base (11) has a through-opening (12) for axially guiding the guide rod (7), and a first end section of the spring element (8) comes into contact with the base (11).
