Abstract
A motion guide device is able to damp a moving block from vibrating in a direction perpendicular to an axis of a raceway rail. A damping plate with a surface facing a surface of a raceway is provided at a moving block body. The surface of the damping plate is set to be in contact with the raceway rail or is set such that a gap between its surface of the raceway rail is as close to zero as possible. When vibration occurs from the raceway rail or the moving block, the surface of the raceway rail and the surface of the damping plate 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.
