PURPOSE: An air discharge structure of an oil pump for an automatic transmission is provided to prevent an oil spill by closing a discharge path of a main pump while a sub pump drives and the main pump stops, thereby maintaining the charged state of oil. CONSTITUTION: An air discharge structure of an oil pump for an auto transmission comprises a main pump(10M), a sub pump(10S), an air outlet(AM), and a chimney passage(50). The sub pump is arranged with the main pump in parallel. Inhalation flow paths(15M,15S) of both sides of the sub pump are connected to the lower part of an oil strainer. The chimney passage interlinks an air outlet to the oil(F) inside of a oil pan(3). |
