BRIEF DESCRIPTION OF THE DRAWINGS FIG.

First, the configuration of the embodiment will be described.

FIG. 1 is a structural explanatory view showing a main structure of a lock device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a control shaft. This control shaft 1
Is provided in parallel with a side portion of a steering column (not shown), and is slidable in an arrow Se direction (hereinafter referred to as a select direction) and rotatable in an arrow Sh direction (hereinafter referred to as a shift direction). It is supported by. A shift lever 2 projects radially from the distal end of the control shaft 1, while a shift lever 2
An engagement plate 4 that can be engaged with and disengaged from a position plate 3 fixed to the vehicle body is protruded. The above structure is
For example, since it has a well-known structure described in a gazette presented in the related art, a detailed description is omitted.

At an intermediate portion of the control shaft 1, a lock plate 5 is fixed so as to protrude in a radial direction. At a position near the lock plate 5, a lock lever 6 having an engagement hole 6a for engaging with the lock plate 5 and restricting the selection operation while the control shaft 1 is shifted to the parking range is provided. ing.
The lock lever 6 is rotatably mounted on the vehicle body from a lock position where it engages with the lock plate 5 shown in FIGS. 2, 3 and 4 to an unlock position where it disengages from the lock plate 5 shown in FIG. Installed. Further, a solenoid 7 is connected to the lock lever 6. The solenoid 7 positions the lock lever 6 at the lock position when energized, and positions the lock lever 6 at the unlock position by a return spring (not shown) in a non-energized state. The driving of the solenoid 7 is controlled by a controller 20. The controller 20 is connected to the ignition switch 9, the park switch 10 and the brake switch 11. When the ignition switch 9 is turned on, the park switch 10 Is detected, the solenoid 7 is energized to move the lock lever 6 to the lock position, and the brake 12
When the brake switch 11 is turned on by depressing, the solenoid 7 is de-energized and the lock lever 6 is moved to the unlock position.

A turning lever 13 is provided near the lock lever 6. The rotation lever 13 includes an engagement pin 13a that engages with the lock plate 5 on the side opposite to the select direction when the control shaft 1 is disposed in the parking range, and the engagement pin 13a and the lock plate 5 In the engaged state, a lever engagement protrusion 13b that engages with the lock lever 6 in the direction of rotation from the lock position to the unlock position is formed, and FIGS.
As shown in FIG. 4, the lever 13b rotates about the shaft 13c from the lock position where the lever engagement projection 13b abuts on the lock lever 6 at the lock position to the unlock position away from the lock lever 6 at the lock position as shown in FIG. It is attached to the vehicle body as much as possible, and is urged by a spring 14 to rotate toward the unlock position. Note that the spring force of the spring 14 is the combined force of this spring force and the spring force inside the solenoid 7,
Is set to be weaker than the spring force of the return spring 1a shown in FIG.

The lock plate 5, the lock lever 6, and the rotation lever 13 described above constitute a restriction means for restricting a shift change of the shift lever 2 from the parking range to another range.

The rotating lever 13 is connected to a stopper 81 of the key cylinder 8 via a push-pull cable 15 as a transmission member. That is, the key cylinder 8 has a structure as described in, for example, Japanese Patent Application Laid-Open No. 63-121551, and an engine key (not shown) is provided inside the cylinder case 82.
And a key rotor 83 that is rotated by inserting and turning. The key rotor 83 is rotatable to four positions of a lock position LK, an accessory position ACC, an on position ON, and a start position ST by operating an engine key. The switching of an ignition switch 9 provided integrally with the ignition switch 9 is performed. The lock position LK is a position where the engine key can be inserted and removed and the steering is locked. Accessory position A
CC is a position where the engine is stopped but electrical components can be used. The ON position ON is a position where the engine can be driven. Start position S
T is a position where the start of the engine is started by turning the starter motor. FIGS. 1, 2, and 3 show a state where the key rotor 83 is arranged at the lock position LK, and FIGS. 4 and 5 show a state where the key rotor 83 is arranged at the on position ON.

The stopper 81 is supported by the cylinder case 82 so as to be rotatable about a pin 811. When the rotating lever 13 is located at the unlock position, the stopper 81 is The pawl portion 84 is pulled to the cable 15 by the urging force of the spring 14 so that the claw portion 84 is disposed at a lock position where it can engage with the protrusion 85 formed on the key rotor 83, and the key rotor 83 is moved to the accessory position ACC.
From the lock position LK. On the other hand, when the rotating lever 13 is located at the lock position, the stopper 81 is pushed by the cable 15 and
The claw portion 84 is arranged at an unlock position where it is arranged outside the cylinder case 82, and the key rotor 83 can rotate to the lock position LK.

Next, the operation of the embodiment will be described with reference to FIGS.

(A) At the time of the parking range In the parking range, as shown in FIG. 2, the lock plate 5 comes into contact with the engagement pin 13a of the rotating lever 13, and the return spring 1a moves in the direction opposite to the selection direction Se. The return force overcomes the spring force of the spring 14 and the return force of the solenoid 7 (the solenoid 7
When power is not supplied), the rotating lever 13 is arranged at the lock position,
At the same time, the lock lever 6 is held at the lock position. At this time, in the key cylinder 8, the stopper 81 is pushed by the cable 15 and is placed at the unlock position, so that the key rotor 83 can be turned to any position.

Assuming that the key rotor 83 is in the lock position LK, the projection 85 is arranged at a position facing the claw 84 as shown in the figure. In this state, the claw 84 is moved to the projection 85 of the key rotor 83 as shown in the figure. , The rotation of the rotation lever 13 to the unlock position is restricted. Therefore, even if the lock lever 6 is held at the lock position and an attempt is made to perform a select operation in this state, as shown in FIG. 3, the lock plate 5 can only move to the end of the engagement hole 6a and cannot perform the select operation. And
At this time, the select operation force is received only by the lock lever 6 and is not input to the rotating lever 13, so that the cable 15 does not expand or the stopper 81 is deformed.

(B) When the ignition is turned on The ignition switch 9 is turned on from the above state, and the key rotor 83 is turned on as shown in FIG.
When it is turned, the position of the protruding portion 85 is shifted, so that the stopper 81 can rotate to the lock position, and accordingly, the rotation lever 13 can rotate to the unlock position by the spring force of the spring 14. However, the condition that the ignition switch 9 is ON and the park switch 10 is ON
The solenoid 7 is energized according to the condition (1), the lock lever 6 is held in the lock position, and the engagement state between the lock lever 6 and the lock plate 5 is maintained. Therefore, the state in which the select operation is restricted is maintained.

Then, when the brake switch 11 is turned on by depressing the brake 12, the power to the solenoid 7 is cut off, and the lock lever 6 rotates to the unlock position as shown in FIG. Therefore, a select operation can be performed.

Thus, when the shift lever 2 is shifted to a position other than the parking position, the rotating lever 13 is held at the unlocked position by the spring 14, whereby the stopper 81 of the key cylinder 8 is also locked in the illustrated position. The claw portion 84 is held in the position, and is in a state of engaging with the protrusion portion 85 of the key rotor 83. Therefore, in this state, turning the ignition switch 9 to the lock position LK is restricted, and the rotor 8
Operation force for 3 is received by pin 811 of stopper 81
And is not input to the cable 15.

Therefore, in order to set the ignition switch 9 to the lock position LK, the shift lever 2 is shifted to the parking range. Then, the lock plate 5 pushes the rotation lever 13 by the spring force of the return spring 1a to urge the rotation in the lock position direction, and the rotation lever 13 and the lock lever 6 engaged therewith rotate to the lock position, The state shown in FIG. 2 is obtained. Then, the cable 15 is connected to the stopper 8 of the key cylinder 8.
Since 1 is pushed and turned to the unlock position, turning to the lock position LK becomes possible.

As described above, in this embodiment, the lock plate 5, the lock lever 6, and the rotating lever 13 constitute a restricting means for restricting a shift change common to a so-called shift lock device and a key interlock device. Therefore, the configuration is simplified as compared with the case where both are provided separately, and the effect of reducing the labor, weight and cost of manufacturing can be obtained.

Also, even if a select operation is performed in the parking range where the key rotor 83 is in the lock position LK, the operating force is received only by the lock lever 6 and is not input to the rotating lever 13. The operating force is not input to the transmission system such as the cable 15 to the key cylinder 8 side, and the shift lever 2 is
Key range while shifting to a range other than the
Data 83 from ON position to lock position
However, the operating force is received only by the stopper 81.
Input to the cable 15
Thus, the effect of preventing the failure of the transmission system including the above and improving the reliability of the device is obtained.

In addition, in the present embodiment, the lock lever 6 is rotated to the lock position when the solenoid 7 is energized. Therefore, when the electric system of the solenoid 7 or the like breaks down, the shift change becomes impossible. Failure can be prevented. Also, when the rotation lever 13 is in the unlock position and the stopper 81 of the key cylinder 8 is in the lock position, the key rotor 83 can be turned to the accessory position ACC. The engine can be stopped without having to do so, and it is easy to turn off the engine in an emergency.

1 and a transmission member 15 connecting the key 1 to the lock position. The shift lock device restricts the shift change unless the brake is depressed at the time of starting, and the key rotor 83 is turned to the lock position only when the parking range is set. The operation of the key interlock device that allows the engine key to be removed is performed by one device, so that the effect is obtained that the structure can be simplified and the labor, weight and cost of manufacturing can be reduced. And
Even if a shift change is performed during such lock, no input is transmitted to the transmission member 15, and the key rotor 83 is operated toward the lock position while the stopper 81 is located at the stopper lock position. Thus, the operation force is not input to the transmission member 15, and the effect that the transmission system including the transmission member 15 such as a cable can be prevented from failure can be obtained.
