関の可変圧縮比機構。 In a variable compression ratio mechanism for an internal combustion engine, an eccentric bearing is rotatably interposed between a piston pin and a connecting rod, and a compression ratio is varied by fixing and releasing the movement of the eccentric bearing using a locking mechanism. , a first gear extending in the circumferential direction is provided on the outer peripheral surface of the eccentric bearing, an oil chamber filled with oil is formed near the eccentric bearing of the connecting rod, and the oil chamber is filled with the first gear.
A variable compression ratio mechanism for an internal combustion engine, characterized in that a damping member having a second gear meshing with the second gear is rotatably arranged.
