An oil ring () includes an oil ring body () and a coil expander (). The oil ring body () includes a pair of rail portions () each including an end portion of an outer periphery having a land () formed protruding radially outward from each rail portion (). The land () includes an upper axial portion () and a lower axial portion () facing opposite to each other in an axial direction, a tapered portion () having one axial end contiguous to the upper axial portion () via a first curved portion (), and a protruding portion () having one of axial ends contiguous to the tapered portion () and the other axial end contiguous to the lower axial portion () via a second curved portion (). The protruding portion () is protruding in a direction perpendicular to the tapered portion ().
