When the switch 20 is turned on, a transmitter 60 built in the slide door 2 is transmitted by a switch power supply (solar battery, normal battery, rechargeable battery) provided separately, and a signal of the transmitter 60 is transmitted. Activating the receiver 61 for receiving, the motor 62 of the automatic slide opening and closing device 63 of the slide door 2
Is configured to be driven. 64 is a child switching device (lever).

FIG. 17 shows an example of a fail-safe mechanism (safety mechanism). Reference numeral 5 denotes a rear auto-locking device. A fan-shaped lever 66 for rotation is provided, and an end of a wire 67 wound around the fan-shaped lever 66 is connected to a winding rod 69 provided on a substrate 68. A passive gear 71 is meshed with a drive gear 70 of the motor 65, and a take-up rod 69 and a clutch plate 73 are attached to a shaft 72 of the passive gear 71 in addition to the passive gear 71. It overlaps with the lever 69 and is constantly urged by the spring 74 in the direction of arrow b. A clutch pin 75 is provided at the lower end of the clutch plate 73, and the clutch pin 75 is engaged with both the clutch concave portion 76 provided on the passive gear 71 and the long hole 77 provided on the winding rod 69.
When the clutch gear 5 and the clutch recess 76 are engaged, the rotation of the passive gear 71 is transmitted to the winding rod 69, and when the clutch pin 75 and the clutch recess 76 are disengaged, the rotation of the winding rod 69 even if the passive gear 71 rotates. Stops.

[0015] The clutch pin 75 is
The clutch lever 78 is further disengaged, and the shaft 79
Is connected to the engaging portion 38a of the fifth lever 38 by a wire 80, and the fifth lever 38 is opened by opening the outer door handle 7 or opening the inner door handle 24a. When is rotated, the clutch lever 78 is rotated to the left by the wire 80, and the clutch pin 73 is disengaged from the clutch concave portion 76 by hitting the head of the clutch plate 73.

[0016]

Next, the operation will be described. A. Operation when the child switching device (lever) 64 is unlocked When the motor 62 of the automatic slide opening and closing device 63 is energized, the slide door 2 automatically slides and closes by a known operation, and the front side of the slide door 2 is closed. When the lock device 3 is present, it engages with the striker 4, and the rear auto-lock device 5 of the slide door 2 engages with the striker 6. Then, when the rear auto-lock device 5 closes the door to the half-latch, a known switch in the rear auto-lock device 5 is turned on to energize the motor 65, and the drive gear 70 of the motor 65
, The passive gear 71 is rotated by the drive gear 70, and the clutch pin 7 is inserted into the clutch concave portion 76 of the passive gear 71.
5 rotates the engaging take-up rod 69 and rotates the fan-shaped lever 66 via the wire 67. Therefore, the latch of the rear auto-lock device 5 is rotated by the motor 65 to the full latch.

However, in some cases, foreign matter may be pinched by the sliding door 2. In this case, the outer door handle 7 is rushed.
When the door opening operation is performed or the inner door opening handle 24a is opened, the child switching device (lever) 64 is turned on as shown in FIG.
When the child lock pin 30 is switched to the unlock position, the child lock pin 30 slides along the engagement long hole 29 and moves toward the rotation shaft 24, and the third protrusion 35 of the third lever 26 is moved. , So in this state,
Opening the inner door handle 24a to open the rotating shaft 24
2 is rotated clockwise in FIG. 2, the child lock pin 30 is pushed up by the third protruding piece 35 of the third lever 26 that rotates together with the rotation shaft 24, and the second lever 25 is rotated clockwise through the engagement elongated hole 29. 2, the rod 32 connected to the arc-shaped long hole 31 of the second protruding piece 28 of the second lever 25 is moved leftward, and FIG.
0 the third arm 1 of the first lever 15 with the rod 32
8 is moved to the left to rotate the first lever 15 clockwise, and the second arm 17 of the first lever 15 pushes down the first projection 50 of the fifth lever 38 against the elasticity of the spring 52 ( (Fig. 2),
The fifth lever 38 is rotated counterclockwise in FIG. 3, and the wire 80 of FIG. 17 is pulled by the engaging portion 38 a of the fifth lever 38.
When the wire 80 is pulled in FIG.
Since the right end of the clutch lever 78 is moved upward, the left end of the clutch lever 78 is moved downward and the head of the clutch plate 73 is hit, so that the clutch pin 75 and the clutch concave portion 76 are disengaged and the automatic lock is automatically stopped. When the outer door opening handle 7 is opened, the first lever 15 is rotated clockwise in FIG. 2 via the rod 23. Press down 50, 5th lever 3
8 is rotated to the left in FIG. 3, and the wire 80 in FIG. 17 is similarly pulled.

B. Operation when child switching device (lever) 64 is locked By operating child switching device (lever) 64, FIG.
In the state shown in FIG. 19, the rotation shaft 24 is rotated clockwise by the first lever 15 to rotate the third shaft 3 of the third lever 26 as before.
Even if 5 is moved upward, it is missed and remains fully latched. Therefore, unlike the previous case, the second lever 25 does not rotate.

However, in FIG. 3 and FIG.
When the inner lever 4 is rotated left by operating the inner opening handle 24a, the sixth lever 54 fixed to the rotating shaft 24 is rotated leftward, so that the arc-shaped long hole 58 of the lower projecting piece 56 moves rightward, and the arc-shaped long hole 58
The rod 59 engaged with the rod 59 is moved rightward,
At the other end, the fifth lever 38 is rotated to the left in FIG. 3, and the wire 80 of FIG. 17 is pulled to rotate the clutch lever 78 to the left to operate as before. When the outer door opening handle 7 is opened, the first lever 15 is rotated clockwise in FIG. 2 via the rod 23. 3 and the fifth lever 38 is rotated counterclockwise in FIG. 3 to pull the wire 80 in FIG.

[0020]
