Abstract
A speed of an opening-closing action of a back door, for example, is changed from an acceleration area to a deceleration area by way of a constant-speed area, and an opening-closing action of the back door is configured to come to an end in the deceleration area. In the deceleration area, deceleration (a second deceleration in FIG., a fourth deceleration in FIG.) of an opening-closing action of the back door at a point before the opening-closing action of the back door comes to the end is set to be smaller than another deceleration (a first deceleration in FIG., a third deceleration in FIG.) of the opening-closing action of the back door at a deceleration start point of the opening-closing action of the back door.
