Consisting of an intermediate connection part B between the vehicle body and the door, and a lock drive part C in the door, two vehicle body side conduction cables e for transmitting motion to the left and right doors of the rear seat connected to the remote control handle d are connected to the vehicle body floor plate f. It is coupled to a hole in a vehicle body panel h via a vehicle body side fixing member g connected to the end through the lower part, and the vehicle body side fixing member g is connected to the door side at the hole in a door panel j via an intermediate connector i. It is connected to a door-side fixing member l that holds one end of the conduction cable k, and the other end of the door-side conduction cable k is connected to a bell crank lever m in the lock drive unit C.
connected to. An indoor lock knob n is operatively connected to the bell crank lever m, and an interlocking rod o
It is connected to the door lock p via. The wires in the operating handle d through the conductive cables e and k are biased by springs so that they automatically return to and hold the neutral position between the locking and unlocking positions.

In this configuration, when the driver tilts the remote control handle d of the operating section A forward from the neutral position, the bell crank lever m rotates counterclockwise via its spindle via the conduction cables e and k. The door lock p is locked via the interlocking rod o, and when the door reaches the rear from the neutral position, the bell crank lever m is rotated clockwise and unlocked.

On the other hand, by manually operating the indoor lock knob n up and down, the door lock p is activated via the bell crank lever m.
The door-side conductive cable k is arranged so that the locking and unlocking operations by the indoor lock knob n and the locking and unlocking operations by the remote control handle d are performed independently. The end of the bell crank lever m is connected to the bell crank lever m via a play connection mechanism (not shown).

The present invention provides a novel structure for the intermediate connection between the vehicle body-side conduction cable and the door-side conduction cable between the door and the vehicle body in such a remote control device for an automobile door lock.

In the assembly and manufacturing process of a car, the fitting process begins with the car body and door separated, so as mentioned above, the conduction cable is separated into the car body side and the door side, and is assembled into the car body and door separately. Each end must be connected when the door is attached to the vehicle body.

The present invention has been made with attention to the above-mentioned points, and the conductive cable on the vehicle body side and the conductive cable on the door side are fixed in advance to the mounting holes of the vehicle body and the door by fixing members provided at their respective ends. When installing the door to the vehicle body, the two fixing members are connected by a telescopic intermediate connector, which facilitates the installation work of each conductive cable in the process of outfitting the vehicle body and the door, and also provides an intermediate connection between both conductive cables. This makes it easy to open and close the door without any hindrance.
