Abstract
When a guide block is located on each of both ends of a guide rail rollers are situated at a position where they are supported by hard supporting members and of a rail member so that the guide block is positioned at a predetermined position precisely. On the other hand, when the guide block is located at a position in the vicinity of a center of the guide rail the rail member is slightly bent by elasticity of an elastic supporting member in spite of lowering of a position precision in the vicinity of the guide rail due to a warp, a distortion, a bend and the like. Thus, an overload applied to the foregoing rail member and the like is relieved.
