摘要： An automotive air conditioning assembly has a fan that is molded by a technique that inevitably leaves the lower hub and upper rim radially staggered relative to one another. Therefore, a substantial length of the edges of the blades' bases are unsupported by the incomplete hub, and the air forced radially outwardly between the blades has no fan structure to confine it at that point. The invention provides a fan housing having a wall portion specially shaped so as to provide the air confinement function that the missing section of the fan hub cannot.
