機関のピストン。In a piston having a top ring groove and a second ring groove above and below a second land, a notch that is slightly cut from the outer peripheral surface of the piston toward the center of the piston is formed directly below the top ring groove of the second land. Further, a volume space portion is formed on the second ring groove side so as to be connected to the notch and cut deeper toward the piston center side than the notch so as not to be connected to the second ring groove. piston of an internal combustion engine.
