MOTION GUIDE DEVICE AND METHOD OF ASSEMBLING MOTION GUIDE DEVICE

摘要

A motion guide device is provided which is able to damp the moving block from vibrating in a direction perpendicular to an axis of the raceway rail. A damping plate (8) with a surface facing a surface of a raceway (1) is provided at a moving block body (4). The surface of the damping plate (8) is set to be in contact with the raceway rail (1) or is set such that a gap between its surface of the raceway rail (1) is as close to zero as possible. When vibration occurs from the raceway rail or the moving block, the surface of the raceway rail (1) and the surface of the damping plate (8) come into contact with each other. This brings about change in a spring constant of the motion guide device in the direction perpendicular to the axis of the raceway, thereby improving damping performance for the vibration in the perpendicular-to-axis direction.
