Abstract: A shift lever device is used when an assembly of a vehicle is performed while the vehicle is being moved in a state where a shift lever of an automatic transmission gear is in a neutral state, i.e., in a state where wheels can be freely turned. A movable body is driven by a detent pin moved in the acial direction of the shift lever in a state where the shift lever is at a park position. The movable body is coupled to a steering locking device. An operator moves the movable body to a position at which it can be driven by the detent pin of the shift lever in spite of the fact that the shift lever is not at the parking position, so as to enable an igition key to be removed from the steering locking device.

Abstract: A locking apparatus for a shift lever in an automatic transmission of a vehicle which permits the shift lever to move from a vehicle non-driving position to a vehicle driving position by means of an electrically operated member, such as a solenoid, in the presence of a predetermined condition such as that of applying a brake pedal. When the shift lever is located in the non-driving position, a detent pin for inhibiting the shift lever from shifting is engaged with a lock recess formed in a lock member and the lock member is held in a lock position by means for the electrically operated member. Even though the electrically operated member fails to function due to a malfunction or the like, an occupant can manually shift the shift lever from the non-driving position to the driving position in order to move the vehicle.

Abstract: A transmission operating apparatus for automatic transmission wherein, when a shift lever of the automatic transmission is shifted to a specific position such as a parking position, a detent pin provided for the shift lever is engaged with a movable body and is moved to a first position so as to be engaged with detent means so that the shift to another shift position is prevented. A lock is engaged with the movable body which has been moved, together with the detent pin, to the first shift position so that the lock means cannot be separated from the movable body if a driver does not perform any special operation such as footing the brake or the like. Therefore, the movable body cannot be moved to the second position, and the shift lever cannot be moved to another shift position. The movable body is positioned at the second position when the shift lever is positioned at another shift position, while the same is engaged with the detent pin immediately after the shift lever is operated to the specific position.

Abstract: In an automotive power train using a manually shiftable transmission unit and an automatically controlled clutch unit, the clutch unit is operated by an actuator device including an electromagnetic control. This electromagnetic control is controlled by means of an electric switch apparatus comprising a stroke switch assembly and a knob switch assembly. The stroke switch assembly includes a parallel connected combination of first and second switches to be closed in response to the movement of a transmission gearshift in different directions opposite to each other and the knob switch assembly includes a parallel connected combination of third and fourth switches to be opened in response to the movement of a gearshift knob in opposite directions. These switches are controlled in accordance with predetermined schedules.
