Zusammenfassung:The invention mainly relates to a mechanical device (9) for transmitting movement for a combustion engine, comprising: - a connecting rod (10) comprising a connecting rod big end (13) intended to cooperate with a crank pin of a crankshaft and a connecting rod small end (12) having an internal bore (18); - a piston (16) comprising a pin hole (22); and - a piston pin (15) inserted into said pin hole (22) of said piston (16) and into said internal bore (18) of the connecting rod small end (12) in order to provide a rotary link between said connecting rod (10) and said piston (16), characterised in that the piston pin (15) is covered with a surface coating (14a) with a low friction coefficient and the pin hole (22) of said piston (16) or an insert interposed between said piston pin (15) and said pin hole (22) is covered with a layer of a surface coating (14b) with a low friction coefficient.
