According to the present invention, a water proof structure of an HSG motor housing includes, in the HSG motor where a rotation shaft protruding from a shaft hole formed on the bottom surface of the housing is connected to a pulley, a protrusion ring protruding from the bottom surface to surround the pulley in the bottom surface of the housing. According to the present invention, the water proof structure of an HSG motor housing efficiently prevents the penetration of moisture and foreign materials into the housing through a shaft hole gap by the protrusion ring formed in the bottom surface of the HSG motor housing and improves the operation stability of the HSG motor and the lifetime of use. |
