Abstract: A turbocharger includes a wastegate valve, an actuator for the wastegate valve, and a link mechanism linking the wastegate valve with the actuator via a specific rod. A plate is a component of the link mechanism and connects the wastegate valve with the rod or connects the rod with the actuator. The plate includes a body portion in a plate shape and a pin portion protruding from the main body portion. The pin portion is in a tubular shape having a hollow portion opened to its outside. The pin portion is engageable with an other component of the link mechanism on its outer periphery to form a rotation axis of the other component.

Abstract: Positioning of a cover relative to a housing is made at two locations. i.e., fitting between a first intermediate shaft and a first recess and fitting between a second intermediate shaft and a second recess. In this way, a load of the cover is not conducted to an output shaft through a cover-side bearing. Therefore, in a state where the cover is fixed to the housing, an excessively large load is not generated between a cover-side bearing and the output shaft and a housing-side bearing and the output shaft.

Abstract: A turbocharger for an engine includes a compressor impeller, a turbine wheel, a turbine housing, a cover, and a flow passage switching valve. The impeller is for compression of intake air. The wheel drives the impeller. The housing includes first and second exhaust scrolls independently of each other, and a flow passage switching hole. The first and second exhaust scrolls swirl exhaust gas which is discharged from the engine and blow the swirled exhaust gas toward the wheel. The hole guides exhaust gas into the second exhaust scroll. The cover is provided separately from the housing. The valve opens or closes the hole, and includes a movable part having a rotatable shaft and a valving element. The movable part is attached to the cover. The cover is press-fitted to the housing, so that the valve is attached to the turbocharger.

Abstract: A first rod is rotatably connected to a first drive lever shaft and a first valve lever shaft. A second rod is rotatably connected to a second drive lever shaft and a second valve lever shaft. A first predetermined shape portion is formed at a location, which is spaced from an axis of an output shaft by a predetermined distance. A second predetermined shape portion is formed in a second drive lever and is contactable with the first predetermined shape portion. A spring is placed between the actuator and the second drive lever and urges the second drive lever in a predetermined direction, which coincides with a closing direction of a second valve and an approaching direction of the second predetermined shape portion toward the first predetermined shape portion.
