Beschreibung
Zusammenfassung:	A wastegate valve device (40) for a turbocharger includes a valve body (41), a swing arm (43) configured to support the valve body (41), a rotating shaft (42) to which the swing arm (43) is fixed, a drive arm (44) fixed to the rotating shaft (42), and a rod (45) connected to the drive arm (44). The drive arm (44) includes a fixed portion (441) to which the rotating shaft (42) is fixed, a first extension portion (442) where the rod (45) is connected, and a second extension portion (443) extending on the opposite side of the first extension portion (442). The turbine housing is provided with a stopper (47) with which the second extension portion (443) abuts at the time when the valve body (41) is distanced from the wastegate port (36) due to a rotation of the rotating shaft (42) in a valve-opening direction (C2).
