  • Turbocharger
    Patent number: 10934882
    Abstract: A wastegate is attached to a turbine housing of a turbocharger. The wastegate opens and closes a bypass passage. An actuator is coupled to the wastegate via a link mechanism. The link mechanism includes a link rod and a link arm. The longitudinal direction of the link rod in a state in which the bypass passage is fully closed is defined as a width direction of the link arm. The coupling center position in the link arm to which the link rod is coupled is located at a position offset in a direction in which the link rod moves to open the wastegate from a middle of the link arm in the width direction.
