The present disclosure relates to a cylinder having an inner wall formed with fine uneven patterns to improve durability. The fine uneven patterns according to the present disclosure increases oil film pressure between a piston ring and an inner wall of the cylinder, and smoothly supplies engine oil to where the engine oil is insufficient, thereby reducing abrasion between the piston ring and the inner wall of the cylinder.
