To provide an attachment structure of an air-cooled oil cooler for an internal combustion engine which promises great oil cooling effect, is assembled to the internal combustion engine without needing a pipeline of an oil pipe, and uses a small number of components to achieve excellent assemblability.
An internal combustion engine to be mounted on a vehicle has a structure where an axial outer side of a crank case (11), which pivotally supports a crank shaft (20) oriented in a vehicle width direction, is covered by a crank case cover (50). In an attachment structure of an air-cooled oil cooler for the internal combustion engine, an oil cooler unit (70), which integrally includes an oil introduction passage (75i) and an oil lead-out passage (76e) in the air-cooled oil cooler (71), allows the oil introduction passage (75i) and the oil lead-out passage (76e) to respectively communicate with an oil upstream side passage (58) and an oil downstream side passage (59), which are formed in the crank case cover (50), and is attached to a front part of the crank case cover (50) at the internal combustion engine.
