Claims

[Scope of utility model registration request]

A plurality of cylinders are cast into an aluminum cast cylinder block, and reinforcing materials such as steel plates or steel wire windings of a certain width are cast between adjacent cylinders along the axial direction of the cylinders, and molten metal is poured into the reinforcing materials. A cylinder body structure characterized by forming a passage portion that allows the flow of water to the front and rear of the reinforcing material.
