Claims

[Scope of utility model registration request]

The cylinder block body has a cylinder liner that forms a cylinder chamber on the inner wall, and has a water jacket inside that surrounds the outer periphery of the cylinder liner over substantially the entire length in the axial direction. 1. A cylinder block characterized in that a ring-shaped groove is provided in the inner wall of the block body, which is the location where the piston slides fastest between points and the location near the location.
