is rotated, the transmission end 42c is pushed by the pushing end 43a, the transmission lever 42 is rotated against the biasing force of the spring 35, and the door-closing relay cable 22 is pulled.

On the other hand, the door-opening side cable 13 slackens, but similarly to the door-opening side relay member 50 in the case of opening the door, the escape lever 53 rotates relative to the transmission lever 52 due to the biasing force of the spring 38, and the door-opening side cable 13, and its effect is not as great as that of the opening relay cable 23.

When the door-closing relay cable 22 is pulled, the driven end 66b of the forcing lever 8-66 is pulled in the door lock 60, and the forcing lever 6B is rotated counterclockwise in FIG. At this time, since the latch 62 is already in the half-latch position, the pushed end 82c is in front of the forced end flea of the forced lever 86, and the forced end 68a is in front of the forced end 132c.
protrudes behind.

When the transmission lever 42 is further rotated, the forced end 8fia of the forced lever 88 pushes the pushed end 82c of the runner B2 from behind, causing the launch 62 to rotate to the full latch position.

As a result, the rear end of the sliding door 20 is pulled into the vehicle interior, the door lock 80 is locked, the sliding door 20 is fully closed, and its surface is smoothly continuous with the surface of the vehicle body.

"Effects of the Invention" According to the sliding door opening/closing device according to the present invention, the sliding door can be closed, locked, and unlocked in a series of operations using a single power without applying impact to each part with a small force. The door cannot be opened automatically when the mechanism is locked, and can only be opened when it is unlocked, making it possible to simplify the structure and reduce costs, while also considering theft prevention. Moreover, it is possible to reduce the weight and contribute to the weight reduction of automobiles.
