VEHICLE FRONT PORTION STRUCTURE

A cooling unit (42) that is cooled by heat exchange with air is disposed at a rear side in a vehicle longitudinal direction of a power unit (16). Further, a cooling fan (48) is disposed at a rear in the vehicle longitudinal direction of the cooling unit (42). Further, catalytic converters (60A), (60B) are disposed at a rear side in the vehicle longitudinal direction of the power unit (16). A periphery of these catalytic converters (60A), (60B) is surrounded by a heat insulator (70). A duct portion 74, that communicates an interior of the heat insulator (70) and a space between the cooling unit (42) and the cooling fan (48), is provided at this heat insulator (70).
