A cooling apparatus of a blower motor for a vehicle is provided to reduce noise caused by leakage of air by forming an air leakage prevention part between a cooling passage and a mounting hole of a blower case. A cooling apparatus of a blower motor(12) for a vehicle comprises a ventilating fan assembly(10) and a blower case(20). The ventilating fan assembly is installed inside the blower case through a mounting hole, and includes a fan(11), the blower motor and a motor housing(13) accommodating the blow motor. A cooling air passage(13a) is formed on the motor housing. A portion of air introduced through an air intake(21) formed at an upper surface of the blower case is transferred to the cooling air passage through a cooling passage(23). An air leakage prevention part(24) is formed at a region(G) between the cooling passage and the mounting hole. |
