ABSTRACT:
An automatic transmission for use in an automotive vehicle is comprised of an oil pump assembly adapted to discharge hydraulic oil as operating oil for the automatic transmission. The oil pump assembly is disposed around a stator shaft connected to the stator of a torque converter. The oil pump assembly includes a pump element drivably disposed in a pump housing and covered with a pump cover secured to the pump housing. The pump cover is made of light alloy and integrally formed with a boss inside which the stator shaft is fitted. The boss protrudes in a direction opposite to the pump housing. Additionally, a rigid ring is fitted on the outer periphery of the boss, thereby increasing the rigidity of the boss and preventing the outer peripheral section of the boss from being worn.
