A variable compression ratio apparatus may include a crankshaft, a connecting rod, first and second eccentric links mounted at both sides of the connection rod, respectively, and having one ends at which the piston pin may be eccentrically and rotatably installed, a swing link of which one end may be branched into two parts to form first and second branches, the first and second branches being connected to the other ends of the first and second eccentric links, and a control device connected to the other end of the swing link to control the swing link, wherein the crank arm includes guide surfaces formed in a predetermined thickness at an inner circumferential surface of the crank arm so that the first and second branches of the swing link slide to move between the guide surfaces. |
