ンジンの連通路。 In an engine in which a balancer that works to cancel out the vibrational force caused by the engine's reciprocating mass is installed on the side of the cylinder block parallel to the crankshaft, the upper end opens into the space above the cylinder head and the lower end opens into the crankcase. A communication path is formed in a vertical plane that includes the rotation center line of the balancer, and a lower end opening of the communication path that opens into the crankcase is adjacent to the bearing of the balancer and is connected to the balancer. An engine communication passage characterized by being located above the small diameter shaft part avoiding the weight part.
