Abstract

A connecting rod has a big end bearing eye for attachment to a crankshaft, a small end bearing eye for attachment to a piston of a cylinder, and an eccentric adjusting device for adjusting an effective connecting rod length. The eccentric adjusting device has eccentric rods (15, 16) with first ends that engage on an eccentric lever of the eccentric adjusting device and second ends that engage on pistons (20, 21) guided in hydraulic chambers of the connecting rod. The second ends of the eccentric rods (15, 16) are spherical heads that engage in a corresponding recess (40) in the respective piston (20, 21), and the respective piston (20, 21) further accommodates a retention element (41), one segment of which rests on the spherical-headed end of the respective eccentric rods (15, 16).
