DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device, and more particularly to a key lock end mounting structure for a shift lock mechanism interlocked with a key lock mechanism.

[0002]

2. Description of the Related Art A shift lever device of this kind prevents a shift lever from being moved from a parking position by a key lock mechanism when the vehicle is parked with an engine key removed, and the shift lever is in a position other than the parking position. When driving after the engine is started, the driver must not depress the brake pedal to move the shift lever from the parking position. It is a combination.

That is, when the shift lever is shifted to the parking position (P) for parking the vehicle to stop the engine, and when the engine key is removed, the key cylinder is engaged with the steering shaft to lock the key, and , The electric system of the vehicle is cut off, as shown in FIG.
The actuator 8 such as a solenoid is turned off, the plunger 7 is pushed out by the spring force of the actuator 8, and the lock lever 6 connected to the plunger 7 is moved about the shaft 5 from the inside of the detent cutout 3 to the outside thereof. The key lever 10 connected to the key lock mechanism by the key lock end 11 such as a joint rod is restricted on the key lock mechanism side. Pin 10a contacts the lock lever 6, and the lock lever 6
, The position pin 2 is restrained in the parking position P and cannot move,
Therefore, the shift lever cannot be operated.

Next, when the engine key is inserted and turned to release the key lock for running the vehicle, the key cylinder comes out of the steering shaft, the steering shaft can be rotated by the steering wheel, and the key lever 10 is rotated. Is released and the vehicle can be rotated. However, since the electric system of the vehicle is connected and the actuator 8 is turned ON, the lock lever 6 is held in the detent notch 3 so that the locked state is maintained. Still, the position pin 2 maintains the state where it is restrained by the parking position P.

Therefore, when the brake pedal is depressed for starting the vehicle, the power supply to the actuator 8 is cut off, and the lock lever 6 is moved to the detent notch 3 as shown by an imaginary line.
, The restraint of the position pin 2 is released, so that the shift lever can be shifted to a required range by depressing the knob of the shift lever and depressing the position pin 2.

The shafts 5 and 9 are supported on the gate wall surface where the detent cutout 3 is opened, and the actuator 8 is fixed to the gate wall surface. In addition, a support lever 13 for holding the position pin 2 in coordination with the key lever is rotatably supported coaxially with the shaft 9. When the position pin 2 is pressed down in the state shown in FIG. Is not transmitted directly to the key lever 10 to protect the key lock mechanism. The key lever 10 and the support lever 13 are urged by a spring in a direction to clamp the position pin 2.

[0007]

However, in a shift lever device having a lock mechanism in which a key lock mechanism is combined with the shift lock mechanism as described above, the shift lock mechanism and the key lock mechanism are mechanically connected by a cable or the like. The connection was made by bending the tip of the key lock end 11 into a substantially L-shape, and fitting the tip into a hole formed in the key lever 10 connected to the key lock mechanism. The other end of the key lock end 11 is formed with a screw, and a shift cable is connected to the shift cable so as to be adjustable in length by a coupler screwed to the screw.

[0008] For this reason, the assembling work of the key lever 10 and the key lock end 11 is a simple operation that is sufficient if the tip of the key lock end 11 bent into a substantially L shape is inserted into a hole formed in the key lever 10. However, it is necessary to adjust the length of the cable thereafter, and in particular, this operation must be performed after assembling the shift lever device to the vehicle body, which is troublesome and poor in workability.

Therefore, the present invention enables one-touch assembly of a key lock lever and a key lock end, and
Provided is a shift lever device in which the length can be adjusted with one touch.

[0010]

SUMMARY OF THE INVENTION A shift lever device according to the present invention is an automatic transmission for a vehicle having a shift lock mechanism that permits a shift of a shift lever from a predetermined position during a predetermined operation interlocked with a key lock mechanism. In the shift lever device, a columnar projection is provided on a key lever that is interlocked with the key lock mechanism, and a substantially U-shaped groove for fitting a key lock end in the columnar projection is formed in a radial direction.
On the cylindrical cap which is slidably fitted in the columnar projection in the axial direction, a groove overlapping with the substantially U-shaped groove is formed in the radial direction, and the groove is substantially perpendicular to the innermost part of the groove in the axial direction. A fitting portion is formed, and a protruding portion over which the key lock end passes over is formed between the fitting portion and the groove.

Therefore, when the cap is fitted in the columnar projection in the axial direction to overlap the groove, and the key lock end is fitted in the groove, and then the cap is pushed deeply into the columnar projection, the key lock end swings right and left. And the connection is ensured without engaging the groove of the cap and coming off.
