Zusammenfassung:	A wastegate valve device for a turbocharger includes a valve body, a swing arm configured to support the valve body, a rotating shaft to which the swing arm is fixed, a drive arm fixed to the rotating shaft, and a rod connected to the drive arm. The drive arm includes a fixed portion to which the rotating shaft is fixed, a first extension portion where the rod is connected, and a second extension portion extending on the opposite side of the first extension portion. The turbine housing is provided with a stopper with which the second extension portion abuts at the time when the valve body is distanced from the wastegate port due to a rotation of the rotating shaft in a valve-opening direction.
