The guideway member has an upper surface extending slantwise with respect to a horizontal lower surface and the raceway grooves are cut slantwise on at least widthwise opposing sides near the upper surface of the guideway member. The slider is recessed at the middle thereof to have widthwise opposing wings to fit over the guideway member for sliding movement.
