Claims

[Scope of utility model registration request]

A concave portion for an oil jacket is formed on the side surface of the cylinder block body, and the cylinder peripheral wall surface of the cylinder block body is formed on the inner surface of an oil jacket cover that is attached to the side surface of the cylinder block body so as to close this side opening. A protrusion protruding toward the side is formed, and a protrusion is formed in the gap between the cylinder peripheral wall surface of the cylinder block body and the protrusion of the oil jacket cover from one end side of the cylinder block body to the other end side. In the engine cooling device, an oil jacket for cooling the engine is formed so that engine oil flows along the peripheral wall surface of the cylinder. An engine cooling device characterized in that a flow blocking part is formed on the oil jacket cover and blocks the flow of engine oil in the space above the protruding part of the oil jacket cover.
