In a piston of an internal combustion engine equipped with a backup ring that seals the joint portion of the piston, a pressure passage is provided on the side surface portion of the backup ring located on the combustion chamber side to communicate the back space of the ring with the combustion chamber side. A piston ring device for an internal combustion engine, characterized by:
