ベアリングのロツク機構。 An eccentric bearing is rotatably interposed between the piston pin and the connecting rod, and a lock pin slidably provided on the connecting rod side is inserted into the lock pin guide groove formed on the outer peripheral surface of the eccentric bearing. In a locking mechanism of an eccentric bearing in a variable compression ratio mechanism, the surface of the lock pin engaging hole of the eccentric bearing facing the lock pin guide groove is inclined in a direction away from the lock pin engaging hole. An eccentric bearing locking mechanism characterized by a sloped surface.
