Abstract
In an internal-combustion engine, a piston pin of each piston is integrally and rigidly fixed to the small end of a connecting rod. The piston pin is pivotally coupled to the piston by way of a metal bearing interposed therebetween, and is held thus in coupled state by bearing caps respectively clamping the ends of the piston pin against the piston over an interposed metal bearing. The greater part of the piston pin is of a large diameter, and its length is only slightly less than the outer diameter of the piston, whereby a practically maximal bearing area is afforded between the piston and piston pin for withstanding forces transmitted therebetween.
