Claims

[Scope of utility model registration request]

In an oil scattering prevention structure for an internal space of an engine, in which a shielding plate is installed to cover a cylinder block side passage opening of an oil return passage that returns lubricating oil from a cylinder head to an oil pan, The bottom dead center of the piston in the cylinder bore on which the piston slides, leaving a range in which the connecting rod, which connects the piston that fits in the cylinder part and the crankshaft that fits in the skirt part of the cylinder block on the oil pan side, can move. A structure for preventing oil scattering in an internal space of an engine, characterized in that a side port is covered with the shielding plate.
