Abstract
A locking apparatus for a shift lever provided for operating an automatic transmission, where if the shift lever is not located in a non-driving position such as a 'P' range, a key rotor cannot be rotated to a lock position and, if the key rotor is not rotated from the lock position to an operating position, the shift lever cannot be moved from the non-driving position. An extension is interlocked with a detent pin which serves to hold the shift lever in the non-driving position. The extension is arranged to move along the axis of the key rotor in interlocked relationship with the movement of the detent pin and to move into and away from the locus of movement of a lock portion which is rotated together with the key rotor. When the extension is moved into the locus, the extension inhibits both the movement of the key rotor to the lock position and the shifting of the shift lever from the non-driving position to another position.
