Beschreibung
Zusammenfassung:	A cylinder includes grooving in the inner peripheral surface of the cylinder. In the cylinder, the grooving includes a honed groove and recessed grooves of which the groove widths and groove depths are more than those of the honed groove, the honed groove and the recessed grooves extend in the circumferential direction of the cylinder and include an inclination angle with respect to a direction perpendicular to the axis direction of the cylinder, and a length of 4 mm in which four or more of the recessed grooves exist in the axis direction of the cylinder in a region in which an oil ring slides in a case in which a crank angle is 50° or more and 140° or less can be selected on the inner peripheral surface of the cylinder.
