Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an actuator of a link mechanism for an internal combustion engine capable of suppressing increase in size thereof in an axial direction.SOLUTION: An actuator of a link mechanism for an internal combustion engine includes a wave gear type speed reducer configured to reduce a rotation speed of an electric motor to transmit the same to a 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 has an internal gear that is fixed to the housing, has internal teeth engaged with a flexible external gear, and is formed of a ferrous metal material. The actuator has stopper mechanisms provided integrally with the internal gear and control shaft, and configured to regulate predetermined or more relative rotation by contacting with each other.SELECTED DRAWING: Figure 5 【課題】軸方向への増大を抑制可能な内燃機関用リンク機構のアクチュエータを提供すること。【解決手段】本発明の内燃機関用リンク機構のアクチュエータでは、電動モータの回転速度を減速して前記制御軸に伝達する波動歯車型減速機と、電動モータ及び波動歯車型減速機が固定されるハウジングと、を備え、波動歯車型減速機は、ハウジングに固定され、可撓性外歯車と噛合う内歯を有し、鉄系金属材料により形成された内歯車を有し、アクチュエータは、内歯車と制御軸にそれぞれ一体に設けられ、互いに当接することで所定以上の相対回転を規制するストッパ機構を有する。【選択図】図５
