Title:
LINEAR STOPPER
Document Type and Number:
WIPO Patent Application WO/2011/081209
Kind Code:
A1
Abstract:
Provided is a linear stopper which can reliably stop the movement of an object using a simple structure. The linear stopper is provided with a stopper main body wherein an inclined surface is provided so that a wedge-shaped space has a clearance between the stopper main body and the surface of a guide member, which gradually decreases in an extending direction of the guide member; a rolling element rotatably provided in the wedge-shaped space; and a rolling element pressing means which presses the rolling element in a direction that the rolling element is engaged in the wedge-shaped space, so that the rolling element is brought into contact with the surface of the guide member and the inclined surface of the stopper main body. The linear stopper is provided with a one-way stopper mechanism which restricts the relative movement of the stopper main body toward the larger clearance side of the wedge-shaped space with respect to the guide member using an engagement action caused by a rolling contact of the rolling element within the wedge-shaped space, and allows the relative movement of the stopper main body toward the smaller clearance side of the wedge-shaped space with respect to the guide member using a sliding contact of the rolling element within the wedge-shaped space.
