摘要: PROBLEM TO BE SOLVED: To precisely control the phase of a shaft and prevent occurrence vibration noise in variable stroke characteristic engine. SOLUTION: Since pair driven gears 42a, 42b separatedly arranged at substantially axially central portion 25 are engaged with driving 41a, 41b rotated by an actuator so as to rotate 25, twist deformation is minimized size engine E axial direction can be reduced. Further, since phases displaced from each other, when either direction, it possible backlash between 42b, increase precision controlling reduce resulting backlash. COPYRIGHT: (C)2007,JPO&INPIT
