An oil pump for an automatic transmission includes a housing provided with at least one hydraulic line formed therein. A power source is coupled to the housing and supplies a torque through a drive shaft. Two pumps are disposed respectively at both end portions of the housing and disposed concentrically with the drive shaft in the housing. The two pumps are operably connected to each other through a torque delivery shaft, and pump an oil by receiving the torque from the drive shaft. The drive shaft is inserted into and is operably connected to a first inner rotor of one pump, and is operably connected to the torque delivery shaft connected to a second inner rotor of the other pump through an engaging portion. |
