とするピストン。A cavity is formed in the piston crown part with the cavity center offset from the piston center axis, and a squish lip that protrudes toward the cavity center is provided on the periphery of the opening of the cavity, so that the distance from the piston center axis to the inner wall of the cavity is large. A piston having a squish lip with a longer protruding length, characterized in that a cooling passage through which a cooling liquid is supplied is provided in the piston crown portion along the inner wall of the cavity on the side where the distance is greater.
