Abstract
An automatic transmission locking mechanism including a detent lever rotatively interlocked with a manual shift lever and provided with notches corresponding to the shift positions, respectively, of the manual shift lever for receiving the detent of a detent spring, a rod adapted to be advanced or retracted by the detent lever, a parking gear fixed to the output shaft of the automatic transmission, a pawl having a detent to be engaged with the parking gear in locking the parking gear, a cam slidably mounted on the rod and adapted to push the pawl for turning when the rod is advanced in shifting the manual shift lever to the parking position, a bracket on which the cam runs upward and a spring for releasing the pawl from the parking gear and for retaining the pawl at the released position. A contact surface formed in the free end of the pawl for engagement with the cam is formed so as to reduce the detrimental slip between the cam and the contact surface to the least possible degree.
