2. Description of the Related Art A slide door opening / closing device for a vehicle includes a door closer device, a slide driving device, and an opening / closing control device for controlling them, and is slidably supported on a vehicle body based on an opening / closing command of an operator. Some open and close the sliding door automatically.

More specifically, when an instruction to open the slide door is issued, the door closer device moves the slide door in the fully closed state (full latch state) through the half door state (half latch state) based on the control of the opening / closing control device. In order to enable the opening operation, the latch that restrains the striker fixed to the vehicle body is rotated by the actuator, and the restraint of the striker by the latch is released. Note that the position of the slide door at this time is the minimum open position. When the slide door reaches the minimum open position, the opening / closing control device stops the operation of the door closer device and starts the operation of the slide drive device.

The slide drive device opens the slide door from a minimum open position to a full open position by an actuator under the control of an opening / closing control device. When the slide door is fully opened, the opening / closing control device stops the operation of the slide drive device.

When a slide door closing command is issued,
The slide drive device closes the slide door with the actuator under the control of the opening / closing control device shown in FIG. 11 from the fully open position through the minimum open position to the half latch position, that is, until the latch restrains the striker at this position. .
When the slide door is in the half latch state, the opening / closing control device stops the operation of the slide drive device and starts the operation of the door closer device.

[0006] The door closer device is provided to bring a sliding door in a half-latch state into a full-latch state.

Then, at the time of the closing operation of the slide door, after the door is in the half-latch state, the opening / closing control device stops the operation of the slide driving device and starts the operation of the door closer device. 52b
A predetermined time is required until the latch 52 rotated about the striker comes into contact with the striker 51. Therefore, the slide door is in a free state until the latch 52 comes into contact with the striker 51.

At this time, if the slide door moves due to the tilting state of the vehicle or the backlash of the slide door due to manufacturing tolerances, the striker 51 may be displaced from the optimum position near the opening of the recess 52a. is there. For example, as shown in FIG. 13, when the striker 51 is located at a certain distance or more from the optimum position, a large load is applied to the actuator 53 to rotate the latch 52 in the direction of the arrow. Further, in some cases, the latch 53 cannot be rotated by the actuator 53, and the slide door may not be able to be reliably closed.

In order to absorb the displacement of the latch with respect to the striker and securely close the slide door, it is conceivable to increase the size of the latch and the actuator for rotating the latch. There is a problem that the size is increased.
