Even if 6 is rotated in the unlocking direction, the lock device direct connection lever 37 does not rotate, and therefore the door lock device 18 is not unlocked. On the other hand, when the lock lever 45 is rotated counterclockwise in FIG. 9 to the unlocked position by the door knob (FIG. 8), the slide piece 44 moves the interlocking groove 36c.
2, and as a result, the rotation of the lock release lever 36 is transmitted to the lock device direct connection lever 37, and the interlocking wire 4
The lock of the door lock device 18 is released via 3.

The lock lever 45 is further provided with an interlocking arm 45c with a keyless actuator 46. The keyless actuator 46 has a drive arm 46c that swings around a shaft 46b by a motor 46a, and is fixed on the modular panel 12.

The closer cancel lever 38 is interlocked with the automatic closer via the interlocking bar 47 (FIGS. 6 and 9), and when the interlocking bar 47 is pulled, the autocloser function that has started to work is canceled.

The gist of this embodiment is, for example, the engagement structure between the drive arm 46c of the keyless actuator 46 and the pin projection 45d of the lock lever 45 of the door lock control device having the above-mentioned structure. 11 to 14 show the first embodiment. As described above, the pin protrusion 45d is provided at the tip of the interlocking arm 45c of the lock lever 45 pivotally attached to the base plate 31 by the lock lever shaft 33, and projects toward the base plate 31 side. On the other hand, the drive arm 46c of the keyless actuator 46 is formed with a wedge-shaped portion 46h (see also FIGS. 6 and 7) at the tip thereof, which gradually reduces the thickness toward the tip. More specifically, the lower surface of the tip of the drive arm 46c (the surface facing the base plate 31) is an inclined surface that gradually approaches the upper surface.

Thus, the keyless actuator 46
When the leading end of the drive arm 46c of the lock lever 45 is formed of the wedge-shaped portion 46h, the lock lever 45 is pivotally mounted on the base plate 31, that is, the pin protrusion 4 of the lock lever 45.
When the 5d is close to the base plate 31, the elongated hole 46d of the drive arm 46c can be engaged with the pin protrusion 45d. 13 and 14 show the procedure of the engaging work. First, the keyless actuator 46 is tilted and held, and the wedge-shaped portion 46h is along the base plate 31. Then, the pin protrusion 4 is inserted in the long hole 46d.
5d can be inserted, and after insertion, drive arm 4
If the keyless actuator 46 is fixed to the base plate 31 after making 6c parallel to the base plate 31, the engagement work is completed. When this work is completed, there is no possibility that the pin protrusion 45d will come off from the elongated hole 46d. In other words, the pin protrusion 45d of the lock lever 46
The dimensions of the elongated hole 46d of the drive arm 46c and the wedge-shaped portion 46h are determined so that the two can be joined by the above work and will not come off after the joining.

15 and 16 show a second embodiment of the engaging structure of the drive arm 46c 'and the pin projection 45d. The drive arm 46c 'of this embodiment corresponds to the embodiment in which the tip of the elongated hole 46d of the first embodiment is opened. That is, the drive arm 46c ′ has the opening 4 through which the pin projection 45d of the lock lever 45 enters the tip portion thereof.
The bifurcated portion 6j has a long groove 46d 'extending in the radial direction from the shaft 46b of the keyless actuator 46. Bifurcated part 46
It is desirable that the distance j is smaller than that of the pin protrusion 45d so that there is an appropriate resistance when the pin protrusion 45d is inserted into and removed from the long groove 46d ′.

According to this embodiment, simply the drive arm 4
By simply pressing the tip opening portion 46j of 6c 'against the pin projection 45d and moving them relative to each other, the both can be coupled.

17 and 18 show a third embodiment of the engagement structure of the drive arm 46c "and the pin projection 45d of the lock lever 45. The drive arm 4 of this embodiment.
6c ″ divides the drive arm 46c of the first embodiment into two parts at an intermediate portion in the lengthwise direction (a portion where the elongated hole 46d exists),
The two-divided drive arms 46c ″ 1 and 46c ″ 2 are provided with a coupling means 46k. Two-part drive arm 46
Each of c "1 and 46c" 2 has a half groove 46d ". The size of the half groove 46d" of the two-divided drive arms 46c "1 and 46c" 2 can be arbitrarily set. Coupling means 46
For k, a type using an adhesive (FIG. 17), a locking hook type (FIG. 18), or the like can be used.

According to this embodiment, when the two-divided drive arms 46c "1 and 46c" 2 are divided, a pin protrusion 45d is inserted between them, and then the two divided drive arms are joined by the joining means 46k. , A pair of half grooves 46d "
You can make a long hole by using the pin 4 in this long hole.
5d can be held.

The procedure for assembling the slide door 10 having the above structure will be described below. Sliding door 10

5) and supports the arm 14c of the vehicle outer side interlocking lever 14 and the handle interlocking lever 16b of the interlocking shaft member 16 with the interlocking bar 17
Join with. At this time, the stopper 16f protruding from the interlocking shaft member 16 contacts the U-shaped bracket 15 and the interlocking shaft member 16 is prevented from rotating too much with respect to the U-shaped bracket 15. The hook portion 17b can be easily inserted and locked in the interlocking hole 16d of the interlocking shaft member 16. Further, when the hook portion 17b of the interlocking bar 17 is inserted and locked in the interlocking hole 16d of the interlocking shaft member 16 first, the temporary holding protrusion 16e prevents the end portion of the interlocking bar 17 on the hook portion 17a side from hanging (FIG. 8). Chain line). Therefore, the work of inserting and locking the hook portion 17a into the arm 14c of the vehicle outer side interlocking lever 14 becomes easy.

On the other hand, apart from the above work, the door panel 1
The wire type window regulator 20 and the lock controller 30 are assembled to the modular panel 12 before being connected to 1. After that, when the modular panel 12 is joined to the door panel 11 in the correct positional relationship, the kicking lever 16c of the interlocking shaft member 16 and the input arm 36a of the lock release lever 36 face each other in a separated state. in this way,
The interlocking shaft member 16 rotated by the outside handle 13 on the door panel 11 side and the lock release lever 36 of the lock controller 30 supported on the modular panel 12 side do not need to be mechanically connected at all.

After that, the base plate 31 of the lock controller 30 is also fixed to the inner panel 11b, and the window glass 26 is fixed to the glass bracket 25 of the wire type window regulator 20. In addition, the interlocking wire 43 of the lock device direct connection lever 37 is connected to the door lock device 18,
The door knob interlocking rod 48 of the lock lever 45 is connected to the door knob.

The door lock control device assembled as described above operates as follows. [Lock release operation from outside the vehicle] The child proof lever 41 is in the child proof off position, and the lock lever 4 is
5 is in the unlockable position. When the outside handle 13 is rotated in the unlocking direction by placing a finger on the finger hook 13b, the rotation is transmitted to the vehicle outer side interlocking lever 14 via the interlocking arm 13c and the pressed portion 14d. The rotation of the vehicle outer side interlocking lever 14 is transmitted to the handle interlocking lever 16b of the interlocking shaft member 16 via the interlocking bar 17.
Further, it is transmitted to the kick-off lever 16c via the tubular member 16a. Input arm 3 of lock release lever 36 at all times
The tip of the kick-off lever 16c, which is separated from 6a, comes into contact with the input arm 36a before the tension spring 36e.
The lock release lever 36 is rotated in the lock release direction against the force of. Then, the interlocking switching groove 36c for the lock lever
As a result, the slide piece 44 fitted in the interlocking groove 36c2 rotates the lock device direct connection lever 37 in the same direction, and the rotation of the lock device direct connection lever 37 is transmitted to the door lock device 18 through the interlocking wire 43. , The lock is released.
When the lock release lever 36 rotates, the slide groove 36
The slide piece 40 fitted in d moves in the long groove 41c of the child proof lever 41 and does not affect the child proof lever 41.

[Lock release operation from inside the vehicle] The direct connection shaft 32 is rotated in the lock release direction by the inside handle 32a against the force of the torsion spring 32c. Then,
The inner driving arm 35 pushes the pin portion 40a of the slide piece 40 to rotate the lock release lever 36 in the lock release direction. Therefore, the lock is released similarly to the lock release operation from the outside of the vehicle.

[Child proof operation] When the child proof lever 41 is moved to the child proof on position (chain line in FIG. 9) via the arm 41a, the slide piece 4 is moved.
0 moves in the slide groove 36d of the lock release lever 36 and moves to a position not engaged with the inner driving arm 35. Therefore, even if the direct connection shaft 32 is rotated by the inside handle 32a in this state, the lock release lever 36 does not rotate. In other words, the lock cannot be released from inside the vehicle. On the other hand, when the outside handle 13 is operated, the lock release lever 36 rotates in the lock release direction regardless of the position of the slide piece 40, so that the lock can be released.

[Operation at Locking by Door Knob] When the door knob interlocking rod 48 is pulled by the door knob to move the lock lever 45 to the unlocking impossible position (solid line in FIG. 9), the slide piece 44 fitted in the long groove 45b. Moves relatively within the idle groove 36c1 of the lock lever interlocking switching groove 36c and the long groove 45b of the lock lever 45. Therefore, even if the lock release lever 36 is rotated, the rotation of the lock release lever 36 is not transmitted to the lock device direct connection lever 37, and the lock of the door lock device 18 is not released. At this time, the lock lever 45 is not affected. this is,
The same is true whether the outside handle 13 is operated to rotate the lock release lever 36 or the inside handle 32a is operated to rotate the lock release lever 36.

[Keyless Operation] When a drive signal is applied to the motor 46a of the keyless actuator 46 by the wireless actuator, the drive arm 46c rotates counterclockwise about the shaft 46b. Then, the right end of the long groove 45b in FIG. 8 normally pushes the slide piece 44, and as a result, even if the lock release lever 36 rotates, the lock device direct connection lever 37 does not rotate, so that the lock cannot be released.

The lock controller 30 of the above embodiment
The configuration of is an example. The present invention is based on the lock controller 3
The lock lever 45 is rotatably supported by the base plate 31 of 0, and the door lock device 1 is rotated by the rotation.
8 is unlocked, the interlocking arm 45c of the lock lever 45 is formed with a pin projection 45d, and the keyless actuator 46 is provided with a drive arm 46c that engages with the pin projection 45d. The present invention is widely applicable to general door lock devices that satisfy the condition that the lock lever 45 rotates in the unlockable direction or the unlockable direction by the swinging motion of the drive arm 46c by the drive signal.
