Abstract: PURPOSE: A VCR(Variable Compression Ratio) device with a dual eccentric link is provided to evenly distribute loads to an eccentric link, a piston pin, and a small end portion of a connecting rod as the eccentric link is connected to both sides of the small end portion of the connecting rod. CONSTITUTION: A VCR device with a dual eccentric link comprises a connecting rod(20), an eccentric rod, and eccentric links. The connecting rod comprises a large end portion(22) and a small end portion(21). One end of the connecting rod is connected to a crank shaft so that the large end portion is applied with the torque from an engine. The small end portion with a coupling hole is formed at the other end. Each end of the eccentric links is connected to the coupling hole from both sides, facing each other. The eccentric links are integrally rotated. The eccentric rod is connected to the other end of the eccentric links and turned within a predetermined angle range.
