Abstract

PURPOSE:To prevent blow-by and ensure smooth sliding of the piston in the cylinder by shifting the axis of the piston land section to the thrust side or non-thrust side with respect to the axis of the skirt section. CONSTITUTION:In this piston 1, the diameter of a lend section 11 is made smaller than that of a lower portion of a skirt section 12, and the diameter of a pin hole 13 provided with a pin boss section 14 on the side of an axis Y-Y is made smaller than that on the side of the axis X-X perpendicular to the axis Y-Y. Further, the axis B-B of the land section 11 is shifted by about 30 to 60mu toward the axis X-X with respect to the axis A-A of the akirt section 12 of the piston. With this struc- ture, in the state with the piston 1 tilted toward the right with respect to the cylinder 3 the gap between the land section 19 on the thrust side T and cylinder 3 is reduced by an amount corresponding to the excentricity. Thus, the seal property can be improved, and blow-by can be prevented.
