Zusammenfassung:	To provide an actuator of a variable compression ratio mechanism for internal combustion engine capable of suppressing inclination of a wave generator.SOLUTION: A non-circular part 3711 of a wave generation plug 371 has a first portion 374 that is inside a cylindrical part 3712 in a radial direction, and a second portion 375 that is outside the cylindrical part 3712. In an X-axis direction, an end surface 375a of the second portion 375 on an X-axis negative direction side is closer to a second control shaft 11 than an end surface 374a of the first portion 374 on the X-axis negative direction side.SELECTED DRAWING: Figure 6 【課題】波動発生器の傾きを抑制できる内燃機関用可変圧縮比機構のアクチュエータを提供する。【解決手段】波動発生プラグ371の非円形部3711は、径方向において、円筒状部3712よりも内側にある第１部分374と、円筒状部3712よりも外側にある第２部分375とを有し、X軸方向において、第１部分374のX軸負方向側の端面374aに対し、第２部分375のX軸負方向側の端面375aは、第２制御軸11に近い位置にある。【選択図】図６
