An object of the present invention is to realize a device of simple construction for generating at all times a steady and appropriate friction resistance even if the speed changes relative to the rotational or linear movement of an object and also easily controlling the magnitude of frictional force by changing loads. In other words, when a rotational body (1) is caused to rotate in a state in which a load is axially applied thereto, each roller (2) rolls while in contact with the rotational body (1) and a receiving body (3). Since each roller (2) is forced to move along the rotational track of the rotational body (1) by being prevented by a cage (4) from rolling in a direction inclined at a predetermined angle relative to the rotational track of the rotational body (1), a friction force in proportion to an axial load is generated between each roller (2) and the rotational body (1) and the receiving body (3). At that time, since each roller (2) slips while rolling, combined sliding friction and rolling friction are generated, whereby a steady resistance can be obtained.
