Abstract
A crankshaft of an internal combustion engine includes a crank journal, a crank pin, and a crank web. The crank journal is to be supported by a crankcase and to be rotatable around a crankshaft axis. The crank pin has a crank pin axis substantially parallel to the crankshaft axis to support a connecting rod which is rotatable around the crank pin axis. The crank web is provided between the crank journal and the crank pin to connect the crank journal and the crank pin. The crank web has a hole which extends from one side face of the crank web and passes in a vicinity of a connection section between the crank pin and the crank web when viewed in an axial direction along the crankshaft axis.
