, a manual operation mechanism (G) consisting of an appropriate linkage means (numerical omitted) that links the fully open restraint means (C), etc. is provided, but this mechanism is not directly related to the present invention.
A detailed explanation thereof will be omitted.

This embodiment has the above configuration.

By moving the operating handle (22) from the non-operating position to the door-opening operating position, the locking device (B) is first released by moving to the intermediate position.

Thereafter, when the operating handle (22) reaches the door opening operating position, the switch (26) is operated while the locking device (B) remains released, and the motor (7) is operated.
) rotates forward, allowing you to reliably hear the sliding door (2) up to its fully open position.

Furthermore, by moving the operating handle (22) from the non-operating position to the closing door operating position, the fully open restraining means (C) is first released by moving to the intermediate position, and then the operating handle (22) is moved to the intermediate position. When the door closes the operating position, the switch (25) is activated and the motor (7) is activated while the fully open restraining means (C) remains released.
) can be reversed to reliably close the sliding door (2) to the fully open position.

As is clear from the above, according to the present invention, the actuation system of the door moving device and the release actuation system of the restraint means for fully opening the sliding door are separate systems, and the operation system of the door moving device is separated from the system for releasing the restraining means when the sliding door is fully opened. When opening or closing the door, the restraining means is first released and then the door moving device is activated, so if the door moving device is activated even though the restraining means is not released, unreasonable force may be applied to the sliding door. There is almost no risk of erroneous operation or malfunction, such as activation, and the operation is reliable, and the restraint means can be released while the operating handle is operated over a certain amount. There are many advantages such as no need to set the release timing, release time, etc. in advance, no need to adjust them, and convenient handling.

Furthermore, in the present invention, as described above, the operating system for the door moving device and the releasing operating system for the restraining means are separate systems, so no matter how the door moving device is operated from outside the vehicle, the restraining means can be released. Since the door cannot be opened by thieves, the possibility of the door being opened by thieves is small, and this is useful as a theft prevention measure.

Furthermore, in the present invention, since it is only necessary to mechanically link the operation handle and each restraint means, there is no need to use an expensive electric actuator, etc., and it can be manufactured at low cost. It also has the advantage that there is no need to pay attention to the means of supplying power to the device.

In addition, in the present invention, the operation handle for opening the door and the operation handle for closing the door may be provided separately. If the door can be opened and closed by moving in one direction and the other direction, the structure will not only be simpler, but also
It is also convenient to handle.

In addition, in the dual embodiment, the wires (34) (4
2) is fixed to the driven J-i' (27) (28), and the wire (3) is connected through the driven piece (27) (28).
4) (42) is connected to the operation handle (22), but for example, the wire (34) (42) is directly attached to the operation handle (22), and the operation handle (22) is moved to the door closing operation position. If the wire (34) is moved, the wire (34) should be made to slack, or if the operation handle (22) is moved to the door opening operating position, the wire (42) should be made to slacken when the door is fully opened. ) side terminal moves in the elongated hole (shown in the figure) drilled in the release lever (20), and prevents the operating force of the operating handle (22゜) from being transmitted to the release lever (20). Good too.
