造。In an engine crankshaft structure in which a plurality of pins and journals are connected to the intermediate arm between the front end journal and the end journal via arms,
At least one of the plurality of arms before and after the intermediate arm does not have a counterweight in axial symmetry with respect to the intermediate arm, and the fixed counterweight does not maintain balance with respect to the crankshaft. The engine crankshaft structure is characterized in that the mass of the counterweights provided on both arms of the middle arm is smaller than that of the other counterweights.
