構の偏心ベアリング。 A variable lock pin is rotatably interposed between the piston pin and the connecting rod, and has a lock pin guide groove provided on the outer circumferential surface for guiding the lock pin slidably provided on the connecting rod side to the lock pin engagement hole. In an eccentric bearing for a compression ratio mechanism, the outer diameter of the eccentric bearing is composed of a small diameter part and a large diameter part, and the lock pin guide groove and the lock pin are provided on the large diameter part side where the wall thickness in the circumferential direction is thicker than on the small diameter part side. An eccentric bearing for a variable compression ratio mechanism characterized by having an engagement hole.
