Next, when manually opening and closing the slide door 1, the auto lock 47 is operated by the switch of the vehicle 2 only when the door lock knob 50 is pushed up, the key hole lever 51 is rocked, or when the slide door 1 is fully closed. When the clutch rod 44 interlocked with the chain 6 is moved upward, the slide plate 31 of the unlocking device 25 is moved upward and the tip portion of the engaging pin 32 is disengaged from the chain 6 or the like to release the engaged state, and the chain 6 or the like is released. Is a free state that can be rotated.

After that, even if the sprocket 16 and the chain 6 are engaged with each other by operating the inner door handle 40 and the outer door handle 41, the chain 6 and the like idle and the slide door 1 slides sideways.

〔The invention's effect〕

In short, according to the present invention, the endless chain 6 or the like is mounted on the inside of the slide door 1 so as to be free or fixed, and the sprocket 16 linked to the door engine 14 is engaged with the chain 6 or the like, and the lower end is pivoted to the vehicle 2. Since the slide link 17, 17a supported by the slide base 1 is mounted on the movable base 18 which is slidable in the opening and closing direction of the slide door 1 through the elevating links 20 and 20a, the slide door 1 is slidable. When the door opens and closes, the sliding door 1 slides in and out of the vehicle 2, and at that time, the sprocket 16 moves in and out with the sliding door 1 because it is engaged with the chain 6 and the like, and therefore the door engine 14 also moves in and out. This allows the driving force of the door engine 14 to be directly transmitted, eliminating the need for a complicated transmission mechanism as in the past, simplifying the mechanism, and reducing the cost. Out of the engine 14 does not work inertial force in order to be perpendicular to the sliding direction of the sliding door 1, the opening and closing of the sliding door 1 can be prevented from swaying large sliding door 1 even if the stopped halfway.

Also, when the door engine goes in and out, slide links 17,17a
The swingable base 18 slides in and out by the swinging movement of the door engine 14, while the swinging of the lift links 20, 20a allows the door engine 14 to move up and down. The moving amount of the movable base 18 that rises slightly is absorbed, and by moving in and out while moving horizontally, the sprocket 16 and the chain 6 etc. should be kept in a hooked state, so that the chain 6 etc. Similarly, even if a member that easily causes slack is used, the sprocket
It is possible to prevent problems such as disengagement of the engaging parts such as 16 and chain 6, etc., and even when using a member such as a rack that does not cause slack, securely maintain the engaged state of sprocket 16 and chain 6, etc. Moreover, since the door engine 14 and the sprocket 16 are not overloaded and the chain 6 and the like are freely selectable or fixed, the automatic and manual switching mechanism and operation can be simplified.

Further, since the balance spring 19 having a predetermined tensile force for canceling the weight of the door engine 14 is interposed between the movable base 18 and the vehicle 2 when the movable base 18 slides, the balance spring 19 causes the door engine 14 to move.
At the time of sliding, the weight of the door engine 14 is canceled and the door engine 14 is slid in a substantially no-load state, so that the door engine 14 can be made small and lightweight without loss of driving force when the sliding door 1 is opened and closed. Etc. The practical effect is enormous.
