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. 3, a fourth deceleration in FIG. 4) 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. 3, a third deceleration in FIG. 4) of the opening-closing action of the back door at a deceleration start point of the opening-closing action of the back door.

Abstract: A vehicle door handle mounting structure (1) includes: a vehicle door (3) including a decoration member (5) mounted on a front side of an outer panel (31) and having a coupling portion (522) that is placed in an opening (312) of the outer panel (31); a door handle (4) mounted in the decoration member (5); and a bracket (9) coupled to the coupling portion (522) from a back side of the outer panel (31) and, together with the decoration member (5), holding the outer panel (31) therebetween.
