Claims

[Scope of utility model registration request]

In an engine in which rolling bodies are provided on the skirts on both sides of the piston where lateral pressure is applied, and the piston and cylinder are brought into rolling contact by these rolling bodies, the skirt surface is divided into the zone where the force transmission W body is attached and the area downward from this zone. and a lower zone following the lower zone, the zone where the rolling body is attached is formed lower than the lower zone, and the gap between the skirt surface and the inner surface of the cylinder is larger than the gap in the lower zone.
