Abstract

A drain structure for a fan motor prevents water from entering a discharge hole in the casing of the fan motor. A guiding passage is in opposed relation to the discharge hole and includes a front end portion covered by a fan boss section and an outer rib to prevent water from entering through the discharge hole into the casing. The guiding passage receives water discharged from the discharge hole. The discharge hole is formed in a lower portion of a casing cylindrical section. The casing cylindrical section is mounted on a fitting bracket for securement to a radiator.
