Abstract
A linear stopper including a stopper body having an inclined surface with a wedge-like space between the inclined surface and a surface of the guide member with a gap decreasing gradually toward one side of an extending direction of the guide member; rolling elements that are arranged in the wedge-like space so as to be rollable therein; and rolling element pressing means that presses the rolling elements in a direction to bite into the wedge-like space, so that the rolling elements are forced into pressure contact with the surface of the guide member and the inclined surface of the stopper body. A one-way stopper mechanism restricts the relative movement of the stopper body with respect to the guide member toward a side at which the gap in the wedge-like space is large, but allows the relative movement toward a side at which the gap in the wedge-like space is small.
