Abstract
A coupling structure for coupling a piston and a connecting rod has a protrusion formed on the rear surface of the crown of the piston and having a semi-spherical concavity and a threaded portion concentric to the concavity, a substantially spherical small end formed at one end of the connecting rod, a holder holding the spherical small end of the connecting rod slidably in the semi-spherical concavity of the protrusion and a fixing ring having a threaded portion engaging with the threaded portion of the protrusion for securing the holder to the protrusion of the piston.
