Beschreibung
Zusammenfassung:	Provided is an actuator for a link mechanism for an internal combustion engine, which can be prevented from being increased in size in an axial direction. The actuator for a link mechanism for an internal combustion engine of the present invention includes: a wave gear type speed reducer configured to reduce a rotation speed of an electric motor, and to transmit the rotation speed to the control shaft; and a housing to which the electric motor and the wave gear type speed reducer are fixed, the wave gear type speed reducer including: an inner gear, which is fixed to the housing, has inner teeth meshed with the flexible outer gear, and is made of an iron-based metal material, the actuator including a stopper mechanism, which is provided to each of the inner gear and the control shaft, and is configured to restrict relative rotation of a predetermined amount or more when the inner gear and the control shaft are held in abutment against each other.
