ABSTRACT:
An automatic shift lever locking device is capable of locking the shift lever of an automatic transmission in a specific non-driving shift position against movement from this position unless a predetermined condition is met. The device has a detent pin provided on the shift lever and movable in response to pressing of a push button on the shift lever, a movable member engageable with the detent pin, and a lock member engageable with the movable member so as to prevent the detent pin from moving out of a lock position thereby to maintain the shift lever locked in the non-driving position. Therefore, when the shift lever is not locked, the manual force exerted by the driver on the push button is not transmitted to the lock members and other parts mechanically connected to the lock member.
