摘要

PROBLEM TO BE SOLVED: To provide an oil cooler cooling device of an air-cooled engine which enables improvement of the cooling efficiency of an oil cooler.SOLUTION: An oil cooler cooling device of an air-cooled engine includes a fan case 1, a centrifugal fan 2, and an oil cooler 3. The fan case 1 is attached to a front part of a cylinder block 4 and the centrifugal fan 2 is housed in the fan case 1. Cooling air 5 generated by the centrifugal fan 2 is supplied to the oil cooler 3. A cooling air outlet 1b is opened in a peripheral wall 1a of the fan case 1. The oil cooler 3 is disposed in the cooling air outlet 1b. A cooling air guide plate 7 arranged along the oil cooler 3 is provided in the fan case 1. The cooling air 5 in the fan case 1 is guided to the oil cooler 3 by the cooling air guide plate 7.SELECTED DRAWING: Figure 1
