1. A wastegate actuator mechanism configured to be used in a wastegate system of a turbocharger,
wherein the wastegate actuator mechanism comprises a elongated link plate, which has an elongated shape, and a pin that is attached to a lever plate, wherein the pin extends partially through an eye provided in the link plate, and wherein the link plate and the pin are rotatable relative to each other about a rotation axis extending in the longitudinal direction of the pin, wherein the wastegate actuator mechanism further comprises a sliding assembly arranged between the link plate and the pin at the position of the eye of the link plate, wherein the sliding assembly comprises a bushing that is fixedly connected to the link plate and a sleeve that is fixedly connected to the pin, and wherein an inner surface of the bushing and an outer surface of the sleeve are in sliding contact,
wherein at an interface of the bushing and the link plate, the bushing is provided with recessed portions and bulges of material of the link plate are received in the recessed portions, and
wherein the recessed portions of the bushing are notches that are distributed at a regular distance in a peripheral direction on chamfered outer rims of the bushing which are present at each of two axial ends of the bushing.
