徴とする可変圧縮比機構。 A piston fitted into the cylinder so as to be able to reciprocate is connected to one end of a connecting rod via a piston pin, and the other end of the connecting rod is connected to a crank pin of a crankshaft, so that the reciprocating movement of the piston is transferred to the crankshaft. A mutually eccentric outer peripheral surface and an inner peripheral surface are provided between at least one end of the connecting rod and the piston pin or between the other end of the connecting rod and the crank pin. 1. A variable compression ratio mechanism characterized by rotatably interposing an eccentric member having:
