DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a shift lever operating device for an automatic transmission,
Located on the side of the steering column fixed to the body side
Automatic transmission linked to the key interlock mechanism
The present invention relates to a shift lever operating device of a machine. [0002] 2. Description of the Related Art Shift lever operation of this type of automatic transmission
In the device, the system is shifted to the parking position.
The shift lever is shift locked by the lock member.
You. This lock member is a solenoid
Drive between the locked and unlocked positions.
Is set to work. [0003] That is, the shift lever is
When the solenoid shifts to
Rotate the lock member to the lock position, and thereby shift
Shift locking the lever to the parking position
When the brake is depressed when starting, the solenoid
Turns the lock member to the unlocked position when the power is turned off
Shift lever from the parking position to another position.
Is set to shift to
You. Further, the shift lever is moved to a parking position.
Key interlock mechanism only when shifting to
You can remove the jin key and remove this engine key.
When the parking condition is cleared, the lock member and key
The key lock lever located between the lock mechanism and
Locked by the locked key lock lever.
Lock member at the lock position in the unlock direction.
Control. Then, shift the shift lever to the parking position.
When shifting from one position to another,
Operate by inserting the engine key into the key interlock mechanism.
The key lock lever is unlocked by
The lock member can be rotated in the unlock direction.
ing. [0006] SUMMARY OF THE INVENTION However, the shift
Move the lever from the parking position to another position.
When switching, an electrical system failure may occur
And the solenoid may not operate. Such a place
The lock member cannot rotate to the unlock position.
The shift lever is shifted to the parking position.
Will remain. Further, the shift lever is moved to the parking position.
When changing gears from one position to another,
Operation by inserting the engine key into the key interlock mechanism
It is necessary to unlock the key lock lever
However, for some reason, a car is manually
In some cases, they may want to be moved, and measures have been desired. [0008] Further, a lock portion pivoted to a lock position.
The material is shaped into a key lock lever to rotate in the unlock direction.
Is blocked by a regulating member
The material is locked by operating the shift lever in the select direction.
It is set to move in the unlock direction. But,
If you select the shift lever quickly,
The restriction member cannot follow the lock member.
Rotation in the locking direction may not be possible,
Bar shift lock release operation may be uncertain.
Was. The present invention has been made to solve the above problems.
It was made and its purpose was parking.

Claims (1)

(1) A control tube rotatably supported by a side portion of a steering column, a shift lever pivotally mounted on the control tube so as to be able to move up and down in the axial direction, and While being inserted into the control tube and moving in the axial direction with the operation of the shift lever,
A compression rod that rotates integrally with the control tube, a selector member fixed to the compression rod, and a plurality of detent grooves that are selectively engaged with the selector member; A detent bracket that rotatably supports the unit, and a key interlock mechanism that allows an engine key to be inserted and removed only when the shift lever is shifted to the parking position, and that the shift lever is moved from the parking position to another position in conjunction with a brake. A shift mechanism for an automatic transmission, comprising: a lock mechanism configured to restrict movement of the shift mechanism to a position when the shift mechanism is in a parking position. Lever select operation Operation is formed so as to be regulated, and is rotatably supported coaxially with the control tube so as to move from a locked position engaged with the selector member to an unlocked position released from engagement, and is interlocked with a brake A lock member connected to an actuator to be rotated, and a pivot member is rotatably mounted on the detent bracket, and is formed so as to be engageable with the selector member in a non-selection direction side when in the parking position. A key lock lever that is linked to the key interlock mechanism through the key interlock mechanism; and a forced lock release mechanism that manually forcibly drives the actuator and forcibly rotates the lock member at the lock position to the unlock position. The forced lock release mechanism is configured to
A lock release lever pivotally mounted on the bracket side and a lock forcibly rotating the lock release lever manually.
Release lever forcibly driving means and the actuator in conjunction with the rotation of the lock release lever.
The lock member in the lock position by forcibly driving the
The unlock lever to rotate to the unlock position
Actuator provided between the actuator and the actuator
A shift lever operating device for an automatic transmission , comprising a forced driving device.
