The roller (1) has a wheel (2) that is rotated around a horizontal axis (A) in a fork (3). A rotary bearing is rotated with the fork around a vertical axis. The fork is pivoted against a damping resistor relative to a rotary bearing around a horizontally extending pivot axis (S). A fork bar (5) is oriented horizontally and vertically above the wheel around the pivot axis during normal use. An independent claim is included for a movable suitcase.
