1. A parking lock for a transmission of an electric or hybrid vehicle, comprising:
a lock device including an actuatable actuating element and a setting element that is adjustable between a deployed position and a retracted position, the locking device structured and arranged such that, in response to repeated actuation of the actuating element, the setting element is, via a coupling mechanism, adjusted alternately between the retracted position and the deployed position,
a camshaft rotatable about an axis of rotation and a cam arranged on the camshaft that is connected in terms of drive to the lock device, the cam being coordinated with the lock device such that, when the camshaft rotates, the actuating element is actuated by the cam,
a ratchet wheel rotatable about a wheel axis and having a pawl that is adjustable between an engagement position, where the pawl blocks a rotation of the ratchet wheel about the wheel axis, and a release position, where the blocking of the ratchet wheel is released,
wherein the setting element is structured and arranged to adjust the pawl between the engagement position and the release position, and
wherein the setting element has a contact section that is mechanically in contact with the pawl to form a drive connection to the pawl and, for the adjustment of the pawl, tapers along an axial direction.
