Cooling structure for vehicular generator

摘要

To provide cooling structure for a vehicular generator where oil is supplied to an oil jet for cooling a piston located in a required position without forming a dedicated oil passage for cooling a generator, is jetted and can cool the generator. There is provided the cooling structure for the vehicular generator based upon cooling structure for a vehicular generator where a generator provided to one end of a crankshaft (10) is cooled by jetting oil and characterized in that an oil passage (81L) for cooling the piston on the way of which the oil jet (81Lj) for cooling the piston by jetting oil to the piston (30) is formed is arranged on an axis parallel to the crankshaft and an oil jet (87Lj) for cooling the generator by jetting oil is provided to the end of the oil passage (81L) for cooling the piston.
