1. An opening-closing body control device of a vehicle, comprising:
an opening-closing body constituting a part of a vehicle body and partitioning an inside of the vehicle body from an outside of the vehicle body in a closed state;
a drive section to open or close the opening-closing body;
an opening-command detection section to detect an opening command of the opening-closing body by a user; and
a drive control section to control the drive section such that the opening-closing body is opened by a predetermined first speed-change manner when the opening-command detection section detects the opening command in the closed state of the opening-closing body,
wherein said first speed-change manner is configured to comprise a first acceleration area where the opening of the opening-closing body is accelerated, a first constant-speed area where the opening of the opening-closing body is performed substantially at a constant speed, which follows said first acceleration area, and a first deceleration area where the opening of the opening-closing body is decelerated, which follows said first constant-speed area, and
said first deceleration area is configured such that a second deceleration of the opening of the opening-closing body at a point just before the opening of the opening-closing body comes to an end is smaller than a first deceleration of the opening of the opening-closing body at a deceleration start point,
wherein acceleration in said first acceleration area is set to be within a range of 500-800 mm/ss (s=second).
