Abstract
A structure for mounting a piston ring mounted around a piston head of a piston is provided. The structure includes a ring groove formed along the piston head with a guide recess circumferentially formed in the ring groove in a certain section. The piston ring is rotatably fitted into the ring groove. A guide protrusion is formed on the piston ring and is provided in the section of the guide recess such that the guide protrusion is rotated within the section. The structure is configured such that when a plurality of piston rings is mounted around the piston head, rotation sections of the end gaps of the piston rings are not aligned with each other.
