Abstract
【解決手段】インテークバルブの位相が最遅角とCA(1)との間の第1の領域にある場合、電動モータの出力軸とスプロケットとの相対回転数が減速比R(1)で減速されて、インテークバルブの位相が変化される。インテークバルブの位相がCA(2)(CA(2)はCA(1)よりも進角側)と最進角との間の第2の領域にある場合、電動モータの出力軸とスプロケットとの相対回転数が減速比R(2)(R(1)>R(2))で減速されて、インテークバルブの位相が変化される。電動モータの出力軸とスプロケットとの相対的な回転方向が同じである限り、最遅角とCA(1)との間の第1の領域およびCA(2)と最進角との間の第2の領域の両方の領域において同じ方向にインテークバルブの位相が変化される。
