摘要： PROBLEM TO BE SOLVED: To inhibit oil introduced into a ring groove of a piston from adhering on a cylinder again, and to reduce oil consumption.
SOLUTION: This piston 1 has: the ring groove 5 on an outer circumference surface part 2; and energizing grooves 9, 10 at least on one of an upper surface 6 or a lower surface 7 of the ring groove 5. The energizing grooves 9, 10 have asymmetry cross section to orient oil introduced into the ring groove 5 to a piston inner circumference side. When the oil is squashed between the ring groove 5 and a piston ring fitted therein, the oil is made to positively flow to the piston inner circumference side by the asymmetry cross section energizing grooves 9, 10. The oil is thereby inhibited from adhering to the cylinder again and oil consumption is reduced.
